History and Lore
Pearl: The Gem of the Sea
Pearls are among the most ancient and revered gemstones in human history. Unlike most gems that form from minerals in the earth, pearls are organic gemstones formed within mollusks such as oysters and mussels. Their formation occurs when an irritant, such as a grain of sand, enters the soft tissue of a mollusk, prompting it to secrete layers of nacre to protect itself. Over time, these layers form a smooth, lustrous pearl.
Throughout history, pearls have been associated with purity, innocence, and transformation. Ancient Greeks believed that pearls were the hardened tears of joy shed by Aphrodite, the goddess of love and beauty. In Chinese mythology, dragons were thought to hold pearls in their mouths, symbolizing wisdom, power, and immortality. One of the most famous historical accounts of pearls is the story of Cleopatra, who dissolved a pearl in vinegar and drank it to impress Mark Antony with her wealth and audacity.
Pearls have long been associated with royalty and elegance. They were popular among aristocrats in Europe and Asia and were often used in ceremonial and ceremonial jewelry. Today, pearls remain a timeless symbol of grace, sophistication, and enduring love.
Moonstone: The Gem of the Moon
Moonstone is known for its adularescence, a phenomenon in which light appears to stream across the surface of the gem, creating a soft, glowing effect. This effect is what gives moonstone its dreamy, ethereal appearance, reminiscent of moonlight on water.
The name "moonstone" is derived from the Romans, who associated the gem with the moon goddess Luna. The Romans also believed that the gemstone was formed from solidified moonbeams. In Greek mythology, moonstone was linked to the goddess Artemis, and in Hindu tradition, it was believed to be formed from the sweat of the moon god Chandra.
Moonstone has long been associated with love, fertility, and feminine energy. It was considered a lucky charm and was often carried by travelers for protection. In some cultures, it was believed to help with insomnia and sleepwalking, and it was used as a dream stone in rituals and poetry. Moonstone was also referred to as “The Traveller’s Stone”, as it was believed to offer protection during night journeys.
Alexandrite: The Color-Changing Wonder
Alexandrite is the most modern of the June birthstones, having been discovered in 1834 in the Ural Mountains of Russia. It was named in honor of Czar Alexander II, who was about to celebrate his 16th birthday. The gemstone gained immediate popularity due to its unique color-changing property, which is known as pleochroism.
Under daylight or fluorescent light, alexandrite appears green or greenish-blue, but under incandescent light, it shifts to a deep red or purplish hue. This color change is so striking that it was often compared to the colors of Russian military uniforms, and the stone became a symbol of national pride and prestige in Russia.
Alexandrite is a rare and highly valued form of chrysoberyl, and its color change is caused by the presence of chromium ions within the crystal structure. The stone was once extremely rare, with Russia being the only source until the late 20th century, when deposits were found in Brazil, Sri Lanka, and Zimbabwe.
The gemstone has been associated with mystery and transformation, much like the way it changes color depending on the light. In some cultures, it was believed that alexandrite could foresee danger, and it was worn as a protective talisman. Czar Alexander II was reported to have worn an alexandrite ring as a personal talisman.
Geological Formation and Sources
Pearl: Born of the Sea
Pearls are organic gemstones, formed within mollusks such as oysters, mussels, and clams. They are composed of nacre, a substance secreted by the mollusk to coat an irritant, such as a grain of sand or a parasite. Over time, layers of nacre build up around the irritant, forming a smooth, lustrous pearl.
Pearls can be natural or cultured. Natural pearls are extremely rare, as they form without human intervention. Cultured pearls, on the other hand, are created through a process in which a small bead or piece of tissue is implanted into a mollusk to encourage the formation of a pearl. This method allows for greater control over the size, shape, and quality of the pearl.
Pearls are found in both saltwater and freshwater environments. Saltwater pearls are typically formed in oysters and include Akoya pearls (Japan), South Sea pearls (Australia, Indonesia), and Tahitian pearls (French Polynesia). Freshwater pearls are formed in mussels and are primarily found in China.
Moonstone: A Feldspar with a Glow
Moonstone is a type of feldspar, a group of minerals that make up a large portion of the Earth’s crust. The gemstone is known for its adularescence, a visual effect in which light appears to float across the surface of the stone. This effect is caused by the interference of light between layers of different feldspar minerals, creating a soft, glowing sheen.
Moonstone is typically white or gray with a silvery sheen, but it can also appear in pink, orange, blue, or multicolored variations. The most valuable moonstones are those that display a blue sheen when viewed against a white background.
Moonstone is mined in various parts of the world, including Sri Lanka, India, Madagascar, and the United States. Sri Lankan moonstone is particularly prized for its strong blue adularescence and is considered one of the finest in the world.
Alexandrite: A Rare and Color-Changing Gem
Alexandrite is a rare form of chrysoberyl, a mineral composed of beryllium and aluminum oxides (BeAl₂O₄). The color change in alexandrite is due to the presence of chromium ions, which absorb certain wavelengths of light and reflect others, causing the stone to appear green in daylight and red under incandescent light.
The first alexandrite was discovered in the Ural Mountains of Russia in 1834, and it quickly became a symbol of Russian pride and prestige. The stone was named after Czar Alexander II, and it was said that the colors of alexandrite mirrored the colors of the Russian military.
As Russian alexandrite deposits were nearly exhausted by the late 19th century, new sources were discovered in Brazil (1987), Sri Lanka, and Zimbabwe. These new sources helped increase the availability of alexandrite, although the stone remains rare and highly valuable, especially when it exhibits a strong color change.
Gemological Properties
Pearl: Luster and Composition
Pearls are organic gemstones, composed primarily of nacre, a combination of calcium carbonate and conchiolin. The surface of a pearl is smooth and lustrous, with a radiant glow that is enhanced by the way light reflects and refracts within the layers of nacre.
Pearls do not have a hardness rating on the Mohs scale because they are organic and porous, and their surface can be easily damaged by abrasion, chemicals, and moisture. The luster of a pearl is one of its most important qualities, with high luster pearls being the most valuable.
Pearls come in a wide range of colors, including white, pink, cream, silver, black, and even multicolored variations. The most famous pearls are white or cream-colored, but black Tahitian pearls and pink freshwater pearls are also highly prized.
Moonstone: Adularescence and Clarity
Moonstone is a type of feldspar, and its most defining feature is its adularescence, the soft, glowing light that appears to move across the surface of the stone. This effect is caused by light interference between the different layers of feldspar minerals within the crystal.
Moonstone typically has a milky or translucent appearance, with a white or gray body color and a silvery or bluish sheen. The most valuable moonstones are those that display a strong blue sheen, especially when viewed against a white background.
Moonstone has a hardness of 6 to 6.5 on the Mohs scale, making it relatively soft for a gemstone. It is also prone to scratches and damage if not handled carefully. Moonstone is not typically faceted, as the adularescence is best displayed in a smooth, cabochon cut.
Moonstone is also known to have inclusions, which are natural features that can affect its clarity. Inclusions are often acceptable in moonstone, as they can enhance the mystical and ethereal appearance of the gemstone.
Alexandrite: Pleochroism and Color Change
Alexandrite is a rare and highly valued gemstone known for its dramatic color change, a phenomenon known as pleochroism. Under daylight or fluorescent light, alexandrite appears green or greenish-blue, but under incandescent light, it changes to a deep red or purplish hue.
This color change is due to the presence of chromium ions within the chrysoberyl crystal structure. The most valuable alexandrites are those that display a strong and vivid color change, with a green to red transition that is easily visible to the naked eye.
Alexandrite has a hardness of 8.5 on the Mohs scale, making it very durable and suitable for daily wear in jewelry. It has a specific gravity of 3.71 to 3.74 and is typically transparent to translucent in appearance.
Alexandrite is rare in nature, and the best specimens are found in Russia, Brazil, Sri Lanka, and Zimbabwe. The color change and clarity are the most important factors in determining the value of alexandrite.
