Originally, this was going to be more of a simple mineral index but turned into what you see below. In essence, Ardans have different names than we have for their precious and semi-precious stone. Using cut and dry definitions, I then added a ‘real-world’ analog to give an idea of what we would call it here on Earth. Whether I include the lexicon going into the third book and beyond, and/or possibly expand it, is up in the air. I figure, should someone have the first or second book, they could easily flip back to the previous books, find the stone in question and be good.
As an aside, What might command a higher value, or be considered of less value on Earth, is not necessarily true on Ardis.

Gemstone Lexicon
Avideriil: An incredibly rare and highly prized gemstone of the Silicon Carbide variety. Real world analog: Moissanite
Bineel: is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure. Real world analog: Colorless Diamond
Dathorite: A gemstone variety of the mineral corundum, an aluminum oxide with trace amounts of vanadium. The color ranges from light to deep purple, the latter of which commands the highest value. Real world analog: Purple Sapphire
Dorreth: A hard object produced within the mantle of a shelled mollusk, composed primarily of calcium carbonate. Relatively spheroid, they can be round, semi-round, button, drop, pear, oval, baroque, circled and double bouldered. They come in several colors with black being the rarest and considered highly prized. Real world analog: Pearl
Ederim: a microcrystalline variety of silica, chiefly chalcedony, characterized by its fineness of grain and brightness of color. Colors can range from white to grey, light blue to dark green, yellow, orange to red and purple to black and is predominantly banded. Real world analog: Agate
Edrasil: A feldspar mineral, found in igneous rocks, such as basalt, gabbro, and norite. It exhibits a strong play of iridescent blue, green, red, orange, and yellow colors. Specimens of the highest quality are known for their vivid displays of color. Real world analog: Labradorite
Ilthidim: A gemstone variety of beryl with colors ranging from pure yellow to golden yellow. Real world analog: Heliodor
Kyanite: A gemstone variety of orange beryl, with colors ranging from pale to dark orange. Real world analog: A variety of Golden Beryl.
Lightning Stone: A hydrated amorphous form of silica only found on the Island of Navinas. Black in appearance, it has a resinous luster akin to blue fire. Real world analog: Black/Lightning Opal.
Nerdravel: A gemstone variety of red beryl, with colors ranging from pink to scarlet. Real world analog: Red/Scarlet Emerald
Nersite: A gemstone variety of corundum, whose colors range from pink to blood-red. Real world analog: Ruby
Pal’ástrine: a deep blue metamorphic rock used as a semi-precious stone prized for its intense color. Real world analog: Lapis Lazuli
Pallexite: A gemstone variety of the mineral corundum whose colors range from crystal to midnight blue and highly prized for its asterisms. Real world analog: Sapphire
Pallgramite: A gemstone variety of beryl, light bluish-green to blue. Real world analog: Aquamarine
Pallsiret: A mineral of the copper variety, deep blue to violet-blue in color. Is in limited use as a gemstone as it can easily weather to Vemelel. Real world analog: Azurite
Seredem: An aluminum silicate that contains fluorine and hydroxyl and used as a gemstone and comes in blue, green, yellow, orange, red, pink, and purple. Reddish-gold or Imperial Seredem, commands higher prices than the other colors. Real world analog: Topaz
Shorasnim: A hydrated amorphous form of silica, which can range in the following colors: white, gray, red, orange, yellow, green, blue, magenta, rose, pink, slate, olive, brown, and black. Real world analog: Opal
Telleel: A black, metastable allotrope of carbon. Real world analog: Black Diamond
Telthramin: Volcanic glass created when felsic lava cools rapidly. Real world analog: Obsidian
Telshir: A black variety of the mineral, chalcedony. It can be black, white, or banded. Real world analog: Onyx
Togrim: A gemstone variety of Olivine, primarily olive green in color, but can range from yellow to brownish-green. Real world analog: Peridot.
Togurad: A gemstone variety of green beryl, whose colors range from light to dark green, often possessing fine inclusions within the stone. Real world analog: Emerald
Thamalos: A violet semiprecious variety of quartz. Its colors and hues range from a light pinkish violet to a deep purple, and exhibit one or both secondary hues of red and blue. Real world analog: Amethyst
Vadador: A gemstone variant of the metastable allotrope of carbon whose colors range from pale to dark red and every hue in between. Real world analog: Red Diamond.
Vemelel: A banded copper mineral ranging in color from pastel green, to a bright green, to an extremely dark green that is almost black. It exhibits banding similar to Ederim. Real world analog: Malachite
Venekel: A feldspar mineral, ethereal in appearance that displays a billowy, ghost-like reflection with a bluish-whitish color emanating from the surface, similar to that of Dorasnim. Real world analog: Moonstone
Zophrite: Fossilized tree resin, which can range from yellow-orange-brown, to whitish color through a pale lemon yellow, to brown and almost black. Other, less common colors include red, green, and blue, of which are highly prized. Real world analog: Amber
