This summary provides a brief explanation of the main gemstone families that we work with on a daily basis in our Bijotuerie. Please note that diamonds are dealt with in a separate article due to their importance and uniqueness.
Corundum is a gemstone family that includes sapphires and rubies. These gemstones consist mainly of aluminum oxide and are the hardest natural minerals after diamonds. Rubies are characterized by their red color, which is caused by chromium, while sapphires come in a variety of colors, most famously blue, but also yellow, green and pink.
Spinels are gemstones composed of magnesium aluminate and often come in a variety of colors, including red, blue, green and black. They have a refractive index of 1.718 and a hardness grade of 8 on the Mohs scale, making them a robust and attractive choice for jewelry. They are relatively rare gemstones and are often found in the same regions as rubies and sapphires, which has meant that historically they have often been confused with them. Their rarity and variety of colors make them particularly desirable and valuable on the gemstone market.
Tourmaline is a complex gemstone family known for its wide range of colors. These gemstones consist of a crystal mixture of silicates and can occur in almost any color, often even multicolored. Popular varieties include green verdelite, blue indigolite and multicolored watermelon tourmaline, which has green and pink zones.
Beryl includes some of the most well-known gemstones such as emerald, aquamarine, morganite and heliodor. These gemstones are mainly composed of beryllium aluminum silicate. Emeralds are known for their intense green color, which is caused by chromium and vanadium. Aquamarines have a blue-green to sky-blue color, while morganite is pink to salmon-colored and heliodor shines in golden-yellow tones.
Garnets are a group of silicate minerals that occur in a variety of colors. The best-known types of garnet are pyrope (red), almandine (red-violet), spessartine (orange), grossular (green to yellow) and andradite (green). Garnets are known for their brilliant variety of colors and their very high light refraction, which gives them a luminous appearance.
