Sapphire has a hardness of 9 making it an excellent choice for all types of jewelry including wedding rings.
Treatments: heat for color and clarity, diffusion for color.
Pink Sapphires have traditionally been found in the gem gravels of Sri Lanka, but recently a major find of intense color stones has been discovered on the island of Madagascar. Colors range from light pink to fuchsia. If the color intensity approaches red, the gem is a ruby, or if the pink color is mixed with orange, the term "padparadsha" is used.
Almost all sapphires of any color have been heat treated to lighten or intensify color, or to try and improve clarity. Since 2001 most pink, yellow and orange sapphire has been diffused with Beryllium to improve color. This treatment is impossible to detect without very specialized lab equipment. Recently, fracture filled stones have also appeared in the market.
Sapphire with a hardness of 9 is among the most durable of gemstones with only diamond being harder to scratch.
Treatments: Heat for color and clarity, diffusion for color, fracture filling for clarity enhancement.
Treatments: Heat treating is almost universal, Beryllium diffusion in African rubies, and fracture filling.
Treatments: Fracture filling of some type is almost universal, typically clear oils, but sometimes epoxy resins.
Treatments: Heating to change color.
Treatments: Assembled stones.
South Seas pearls are graded for color, luster, shape and surface quality. Color ranges from white to golden with the extremes usually being the most expensive. Luster is related to transparency of the nacre with less expensive pearls appearing more chalky. All South Seas pearls are nucleated with a sphere made out of clam shell, but the harvested pearls come in a variety of shapes from spherical to baroque. The more round the pearl is, the higher the value. Surface quality varies from totally smooth to pearls that have small pits or bumps in the surface. While all of these characteristics affect the price of a pearl, the beauty of a pearl is in the eye of the beholder.
Treatments: none (many synthetics however)
With its hardness of 8 and its wide range of available colors, natural spinel makes a great choice for all types of jewelry including rings.
Treatments: Occasional heating
Treatments: irradiation or heating of some rubellite to intensify color.
Blue Topaz has become a standard of the jewelry industry along with garnet, citrine and amethyst. Since scientists discovered that irradiation would turn clear topaz into vibrant shades of blue, the supply has been able to keep up with demand and prices have been very affordable. There is a natural counterpart to blue topaz, but it is rarely seen anymore, since the colors pale when displayed next to their irradiated cousins. Recently, new processes have been used to coat clear topaz with other colors creating a whole new set of affordable gems. These newer processes are merely a surface coating, whereas the blue color is throughout the stone.
Topaz has a hardness of 8 making it superb for all types of jewelry.
Treatments: Irradiation to create blue color. Diffusion and coating to create assorted colors. Heating to remove yellow.
Aquamarine has a hardness of 7 which makes it suitable for most jewelry.
Treatments: Heating at low temperatures removes the yellow component of color, leaving the stone icy blue.
Zircon occurs in a wide range of colors, but for many years the most popular was the colorless variety, which looks more like diamond than any other natural stone because of its brilliance and dispersion. Today the most popular color is blue zircon, which is considered an alternative birthstone for December. Most blue zircon is a pastel blue, but some exceptional gems have a bright blue color. The blue color occurs when heating brownish colored zircons from certain locations.
Zircon is mined in Cambodia, Sri Lanka, Thailand, Myanmar, Australia, and other countries. Cambodia is arguably the world’s premiere source for gorgeous zircon. Sixty-three miles north of Angkor Wat, close to the Cambodian-Thai border, lay the mines of Preah Vihear, the source of some of the world’s finest blue zircon. Remote, primitive and stunningly beautiful, Ratanakiri is another major center for Cambodian Zircon. Ratanakiri literally means “Gemstone Mountain”.
Treatments: All blue zircon has been heat-treated. There are natural colors of zircon though, such as green and yellow.
Jadeite is often used for fine carvings because of it's toughness. 'A' Jade refers to jade that is untreated except for a light wax coating applied after the final polish. Although often purchased in Hong Kong or China, top quality jadeite always originates in Burma.
Black jade from Wyoming is sometimes used to replace black onyx in rings where breakage has been an issue.
Treatments: Usually waxed, often dyed.
Amethyst has been known and used for adornment since ancient times. While the most well known myths revolve around cures for intoxication, amethyst was also used to protect against snakebite, quell excessive stomach acid, beautify the skin, and even combat insect bites. In Greek mythology, a young nymph named Amethystos was being pursued by Dionysis. In her distress, she called out to Artemis for help. Apparently the obvious solution back then was to turn her into stone. When Dionysis saw what happened, he felt remorse and his tears turned the statue purple.
Quartz is seven in hardness so amethyst is a fairly durable stone and can be used in all types of jewelry. With its rich, distinctive color and affordable price, amethyst makes a great addition to any wardrobe.
