Care of the Big 3 https://essamjamaljewelry.com/care-of-the-big-3/ Tue, 10 May 2022 18:27:57 +0000 https://essamjamaljewelry.com/?p=28039

Approaching the issue of care and cleaning starts with understanding a gem’s durability. Corundum, for instance, is one of the hardest natural materials on earth.

Both ruby and sapphire score a 9 on the Mohs hardness scale. This means they can scratch almost anything, and no natural gemstone other than diamond can scratch them. In fact, non-gem-quality corundum is often used to cut and polish other colored stones. Emerald is not quite as hard as ruby or sapphire, but it’s still fairly hard, rating a 7.5 to 8 on the Mohs scale. You can sell the durability of a gemstone, but always remember that toughness can be a concern for some stones. Emerald toughness, for instance, can range from good to poor. So while you can sell durability, don’t oversell it. You should also educate customers about the care and cleaning of their jewelry. Ideally, they should bring their jewelry to you for professional cleaning, but they might not. Protect yourself and explain which care and cleaning methods are safe and which aren’t. As long as rubies and sapphires are not oiled or glass-filled, they can be cleaned with ultrasonic or steam cleaners. Warm, soapy water is safe for cleaning, although strong detergents or vigorous scrubbing can hurt an oiled stone. The widespread use of oiling makes emerald a bigger care-and-cleaning risk than ruby or sapphire. Emeralds should never be subjected to ultra – sonic or steam cleaning. Warm, soapy water is the safest way to clean them. Any detergent should be mild, and gentle rubbing should substitute for scrubbing

Sapphire https://essamjamaljewelry.com/sapphire/ Tue, 10 May 2022 18:11:48 +0000 https://essamjamaljewelry.com/?p=28026

Sapphire

Sapphire and ruby are corundum. Except for the impurity elements that cause color, they are the same chemically, physically, and optically. When the word sapphire stands alone, it usually means the gem is blue. Sapphires also appear in colorless and black variations as well as a wide range of colors. They include violet, green, yellow, orange, pink, and purple. They’re considered fancy-color sapphires and designated by color, as in “yellow sapphire.” Clergy in the late Middle Ages favored blue sapphire for their ecclesiastical rings because its color symbolized heaven. Magicians said it led them to prophecies and allowed them to command spirits. People also turned to sapphire as medicine for eye ailments like cataracts. France’s fourteenth century King Charles V owned “an oval oriental sapphire for touching the eyes, set in a band of gold.” People took sapphire as an antidote for poison and poisonous bites. They believed the stone could clear the mind and skin and cure fevers, colds, and ulcers. They even enlisted it in their fight against the plague—at least those who could afford one did. The superstition and faulty science began to recede in the late eighteenth century. That’s when crystallographers determined that sapphire and ruby were the same species and moved toward categorizing them under the name corundum. For centuries, people used “oriental” to designate stones of a particular hardness that originated east of the Mediterranean. Eighteenth-century gem experts replaced that word with the new word “corundum” when describing sapphires. The word might not have been exact enough, but the idea was right. Corundum, no matter the color, was hard, and its primary source was in the East.

 

Sapphire Sources

 Of the more than two dozen places that produce sapphires, the most famous historical sources are the Kashmir region, which straddles Pakistan and India, as well as Myanmar and Sri Lanka. Kashmir, high in the Himalayas, is renowned for the finest of all sapphires. They are an intense, medium-dark blue, with a unique velvety appearance. The color is called “cornflower” because it resembles the almost fluorescent blue petals of that flower. Burmese sapphires are also beautiful. Their blue is intense, but somewhat darker than the blue of those from Sri Lanka.

Another long-time source of sapphires is Sri Lanka, formerly Ceylon. Connoisseurs put a premium on padparadschas, the pink-orange to pinkish orange sapphires from Sri Lanka. The blue sapphires from that country are called Ceylon. They are often lighter and brighter than stones from Myanmar. Today, the major sapphire sources are Madagascar, eastern Africa, Sri Lanka, and Australia. Madagascar is the most significant source of goodto fine-quality blue sapphire. Thai sapphires are usually dark blue in color, giving some stones an inky appearance. Cambodia supplies many finequality blue sapphires. Australia’s sapphires tend to be dark to very dark bluish green with strong pleochroism. Other sources include mines in Africa and the US, which are known for producing fancy-color sapphires.

 

Treated Sapphires

 The industry views heat treatment as not only common for sapphire, but also as practically an art form. This is because sapphire changes color when it’s “cooked” for the right amount of time and under the right conditions. Improved color is the main objective of heat-treating sapphires, while a secondary goal is improved clarity. Sapphires are also candidates for lattice diffusion treatment. Because the resulting color is sometimes only surface deep, it might disappear during polishing, be chipped away, or lost in other damage. Irradiation is another treatment that’s used on fancy-color sapphires, but the effect is temporary. Strong sunlight alone often destroys the resulting color

 

Sapphire Value Factors

 The most important influence on a blue sapphire’s value is its color, which can appear in a wide array of hues, tones, and degrees of saturation. Sapphire color ranges from very light to very dark violetish blue to greenish blue. The most highly valued sapphires are velvety, violetish blue to blue, in medium to medium-dark tones. Preferred sapphires also have strong to vivid saturation. The saturation should be as strong as possible without darkening the tone too much. Sapphires with these qualities command the highest prices per carat. At the other end of the price scale are commercial-grade sapphires with greenish blue bodycolor or strong greenish blue pleochroism, color zoning, a grayish look, and very light or very dark tone. Prices also vary for fancy sapphires. For example, the pricing on padparadschas can be as exotic as the color itself. Only the most experienced buyers can successfully make their way through a market where sapphires showing the slightest pink or orange might be offered as padparadschas. Generally, the color in the finest padparadschas is an intense pinkish orange hue. There are two phenomena typical to sapphire and both affect value. One is color change. Many color-change sapphires come from Sri Lanka and East Africa. Some in the trade compare them to fine alexandrites. Typically, with strong change, the actual colors are blue and purple. The other phenomenon is asterism. Star sapphires have traditionally been very popular, especially those with blue or black bodycolors. (The socalled black bodycolor is actually a very dark brown). The sharper and straighter its rays and the purer its blue—the less gray it shows—the more valuable a blue star sapphire. Black star sapphires are more fragile than other star sapphires. As you read in Assignment 6, they’re susceptible to parting, so they’re usually cut in a low cabochon for protection against being hit. Black star sapphires are relatively inexpensive. Local pride is also a factor in assessing value in the sapphire market. Buyers in the northern US place a premium on sapphires from the nearby mines of Yogo Gulch, Montana.

Ruby https://essamjamaljewelry.com/ruby/ Sun, 13 Mar 2022 18:13:02 +0000 https://essamjamaljewelry.com/?p=27758

It’s very probable that humans discovered rubies about 3000 bc. The famous Mogok mining area of Burma (now the Union of Myanmar) has been so heavily mined for so many thousands of years that evidence is rare. Yet the caves were once so rich that it’s unlikely that the early cavedwelling, tool-wielding humans who lived there weren’t aware of the dazzling red corundum crystals around them. There are documented references to ruby from far back in history, however. The Old Testament describes the “ruby” in a high priest’s breastplate. Ancient Sanskrit texts honor ruby with the word “ratnaraj,” meaning “king of precious stones.

To be considered ruby, corundum must have a red color that falls within a certain range.

Some gems come in ruby-like colors, and they’re often given names that link them to ruby. These include “rubellite” for red tourmaline, “rubolite” for red opal, “rubicelle” for red spinel, and “rubace” for red-stained quartz.

Ruby’s coveted red ranges from medium to dark orangy red to purplish red. Red must be the dominant color for corundum to be considered ruby. If the stone is reddish orange, it’s considered an orange sapphire. If it’s reddish purple, it’s a purple sapphire

People once believed rubies could ensure a peaceful life. Wearing ruby, they thought, could bring health, wealth, wisdom, and love. People believed that if you wore a ruby in a ring on the left hand or in a brooch on the left side, it would give you a magical ability to live in peace among your enemies.

Ruby Sources

The name Burma is practically synonymous with fine-quality ruby. Political changes led to the renaming of the country as Myanmar, but many people in the gem trade still refer to Burma when they talk about the source of the world’s most prized rubies. The first Burmese mines were located in Mogok, and production fluctuated through much of the post-World War II era. The discovery of a rich deposit in Mong Hsu helped the country get back to the forefront of ruby producers.

Other locations have also emerged as important ruby sources. One of those is the African nation of Mozambique. Ruby production began there in early 2006, and the area has since become the world’s most important ruby source. Sri Lanka is also a significant producer, yielding steady supplies to the ruby market. The quality of rubies from Thailand, Cambodia, and Vietnam sometimes rivals Myanmar’s output. Afghanistan, Kenya, Madagascar, Malawi, Tajikistan, and Tanzania are a few of the world’s other ruby sources.

Mozambique has become the world’s most important ruby source

Most natural rubies are heat-treated to improve their color

Ruby Value Factors

 Color is the most significant factor affecting a ruby’s value. Ruby hues range from orangy red to purplish red. The finest ruby has a pure, vibrant red to slightly purplish red hue and the highest-quality rubies have vivid saturation. Orangy or more purplish rubies are less valuable. Most people prefer medium to medium-dark tones as long as the stone isn’t so dark that it has a negative effect on brilliance. At the other extreme, if the stone is too light, it’s considered pink sapphire, even if the color is vivid. As you’ve read, dealers and retailers often debate the borderline between ruby and pink sapphire. Historically, the word ruby referred to shades of red, which technically included pink. But the names ruby and pink sapphire reflect a wide difference in value. That’s why, given a choice, a seller would prefer to be able to call a corundum gem ruby rather than pink sapphire

Some gems come in ruby-like colors, and they’re often given names that link them to ruby. These include “rubellite” for red tourmaline, “rubolite” for red opal, “rubicelle” for red spinel, and “rubace” for red-stained quartz.

Ruby’s coveted red ranges from medium to dark orangy red to purplish red. Red must be the dominant color for corundum to be considered ruby. If the stone is reddish orange, it’s considered an orange sapphire. If it’s reddish purple, it’s a purple sapphire

People once believed rubies could ensure a peaceful life. Wearing ruby, they thought, could bring health, wealth, wisdom, and love. People believed that if you wore a ruby in a ring on the left hand or in a brooch on the left side, it would give you a magical ability to live in peace among your enemies.

Ruby Sources

The name Burma is practically synonymous with fine-quality ruby. Political changes led to the renaming of the country as Myanmar, but many people in the gem trade still refer to Burma when they talk about the source of the world’s most prized rubies. The first Burmese mines were located in Mogok, and production fluctuated through much of the post-World War II era. The discovery of a rich deposit in Mong Hsu helped the country get back to the forefront of ruby producers.

Other locations have also emerged as important ruby sources. One of those is the African nation of Mozambique. Ruby production began there in early 2006, and the area has since become the world’s most important ruby source. Sri Lanka is also a significant producer, yielding steady supplies to the ruby market. The quality of rubies from Thailand, Cambodia, and Vietnam sometimes rivals Myanmar’s output. Afghanistan, Kenya, Madagascar, Malawi, Tajikistan, and Tanzania are a few of the world’s other ruby sources.

Ruby Value Factors

 Color is the most significant factor affecting a ruby’s value. Ruby hues range from orangy red to purplish red. The finest ruby has a pure, vibrant red to slightly purplish red hue and the highest-quality rubies have vivid saturation. Orangy or more purplish rubies are less valuable. Most people prefer medium to medium-dark tones as long as the stone isn’t so dark that it has a negative effect on brilliance. At the other extreme, if the stone is too light, it’s considered pink sapphire, even if the color is vivid. As you’ve read, dealers and retailers often debate the borderline between ruby and pink sapphire. Historically, the word ruby referred to shades of red, which technically included pink. But the names ruby and pink sapphire reflect a wide difference in value. That’s why, given a choice, a seller would prefer to be able to call a corundum gem ruby rather than pink sapphire

It’s very probable that humans discovered rubies about 3000 bc. The famous Mogok mining area of Burma (now the Union of Myanmar) has been so heavily mined for so many thousands of years that evidence is rare. Yet the caves were once so rich that it’s unlikely that the early cavedwelling, tool-wielding humans who lived there weren’t aware of the dazzling red corundum crystals around them. There are documented references to ruby from far back in history, however. The Old Testament describes the “ruby” in a high priest’s breastplate.

Emerald https://essamjamaljewelry.com/emerald/ Sun, 13 Mar 2022 17:23:13 +0000 https://essamjamaljewelry.com/?p=27736

Emerald, famous for its distinctive green color, is a variety of the beryl mineral species. Other beryl varieties include aquamarine and morganite. The first known emeralds emerged from the mines of ancient Egypt. Estimates of the earliest emerald mining range widely, from about 3500 to 330 BC. The exact date is not as important as this: The obstacles to mining emeralds were overwhelming. And the quality of the stones themselves was, by modern standards, disappointing. These emeralds were small, discolored, and heavily included, but quickly became adornments for the powerful and priestly classes.

Emeralds have been mined for thousands of years

Emerald Sources

 Out of the millions of dollars’ worth of emeralds that come out of the earth each year, about 60 percent come from Colombia. The Puerto Arturo mine is located near the town of Muzo. The most famous of all emerald mines, it still yields some of the best and biggest of the world’s emeralds. The violence that attended emerald mining during the exploitation of the conquistadors, however, continues to be a fact of life in Colombia. Modern-day smugglers prevent the country from reaping the full rewards of this rich natural resource. In one recent year, the Colombian government recorded $11 million in emeralds legally exported to the US. In that same year, US Customs in Miami recorded importation of $42 million in Colombian emeralds. That means perhaps $30 million in emeralds left the country with no accounting. There’s no telling how much other blackmarket emerald made its way out during that or any other year. There are other emerald sources. Brazil, Zambia, Zimbabwe, Pakistan, Afghanistan, and Madagascar account for most of the other 40 percent of the world’s supply. But in each of these countries, manmade problems combine with natural obstacles, such as remote locations and punishing climate, to make getting emeralds to the marketplace a difficult task. Inflation in Brazil, political maneuvering in Zambia, and corruption in Zimbabwe have each at one time or another helped undermine the legitimate emerald market

Major emerald sources are Colombia, Brazil, Zambia, and Zimbabwe

Violence, remote locations, and harsh climates make emeralds difficult to mine

Treated Emeralds It’s common knowledge in the trade that most emeralds are treated. Some are filled with oils, such as cedarwood. Others are filled with polymer resins to hide surface-reaching breaks and improve transparency. As with most treatments, there’s nothing wrong with this as long as the buyer knows that the stone he’s buying is treated.

Emerald Value Factors The most prized emerald hues are green to bluish green. As you read in Assignment 2, emeralds are pleochroic, meaning they display different colors in different directions. The colors are so similar that you usually need special equipment to tell one color from the other. Besides hue, another important factor is saturation, which is a color’s weakness or strength. The highest priced emeralds are those with intense, vivid color saturation. Tone—lightness to darkness—also contributes to emerald value. An emerald’s value is lower if it’s too dark, even if it has high saturation. If beryl is green, but too light in tone and too weak in saturation, it’s simply green beryl, not emerald.
