Dioptase: Dioptase is a relatively rare emerald-green mineral, sometimes tinged bluish or blackish. Crystals are small with a vitreous luster, and is transparent to translucent. Its green is very strong and bright even when compared to the more subtle green of emerald. It forms green to blue-green encrustations and fillings of enamel-like or earthy texture. It is uncommon, and found in the weathered zone (read full)

Emerald: Emerald is the most prized variety of the mineral Beryl. It sometimes fetches higher prices than diamond. It appears as pale green to bright green. Though it is the green variety of beryl, not all gem-quality green beryls are called emeralds; yellow-green stones are called "heliodors;"soft blue-green or even pale green specimens are called "aquamarines." The typical color of emerald is a bea (read full)

Epidote: Epidote is widespread, forms a continuous series of minerals, ending with clinozoisite, which contains no iron. It occurs as crystals elongated and often striated parallel to length, and also as massive, fibrous, or granular habits. Epidote has a yellow-green color, ranges from yellowish-greenish to greenish-black. It has vitreous luster, and is transparent to nearly opaque. It has one perfe (read full)

Petalite: Petalite is a lithium aluminum silicate that is an important ore of lithium. This mineral forms, rarely, as small crystals, which are commonly twinned. More often, petalite forms as large, cleavable masses. It may be white, grey, pinkish, yellow, or colorless. It is transparent to translucent, with a vitreous to pearly luster, and fuses with difficulty. It forms in very coarse-grained, acid igne (read full)

Painite: Painite is an extremely rare borate mineral that was once considered the world's rarest gemstone. It is typically brownish-red to orange-red and was first discovered in Myanmar. Painite crystals are hexagonal and may exhibit pleochroism.With a hardness of 8 on the Mohs scale, painite is relatively hard but is rarely used in jewelry due to its rarity. (read full)

Cinnabar: Cinnabar is a bright red mineral consisting of mercury sulfide. It is the primary ore for mercury extraction. Cinnabar has been used as a pigment and carved into jewelry and ornaments, but due to its mercury content, it is toxic and requires careful handling.With a hardness of 2 to 2.5 on the Mohs scale, cinnabar is very soft.

Wulfenite: Wulfenite is a lead molybdate mineral typically found as thin tabular crystals with bright orange-red to yellow-orange colors. It is a secondary mineral formed in the oxidation zones of lead deposits. Wulfenite is a collector's mineral and is rarely used in jewelry due to its softness.With a hardness of 2.5 to 3 on the Mohs scale, wulfenite is fragile and unsuitable for most jewelry applications.

Zektzerite: Zektzerite is a rare silicate mineral that is typically pink, pale brown, or colorless. It was first discovered in the granite pegmatites of Washington State, USA. Zektzerite is mainly of interest to collectors due to its rarity.With a hardness of 6 on the Mohs scale, it is relatively durable but not commonly used in jewelry. (read full)

Variscite: Variscite is a hydrated aluminum phosphate mineral often confused with turquoise. It displays green to bluish-green colors and has a vitreous to waxy luster.With a hardness of 3.5 to 4.5 on the Mohs scale, variscite is relatively soft and should be worn with care. (read full)

Azurite-Malachite: Azurite-malachite is a combination of azurite and malachite minerals, creating a striking blue and green patterned gemstone. The two minerals often occur together due to their similar formation conditions.With a hardness of 3.5 to 4 on the Mohs scale, it is relatively soft and used in jewelry with care. (read full)

Stichtite: Stichtite is a purplish to pink mineral many times found mixed with green serpentine. Its a hydrated magnesium chromium carbonate hydroxide mineral.With a hardness of 1.5 to 2 on the Mohs scale, stichtite is very soft and used mainly in carvings and ornamental pieces like necklaces or rings. Due to its softness rings and necklaces combine silver or tin to hold the smoothed down pieces in place. (read full)
