loose gemstones
Gemstones are appraised on the color grade matrix which consists of 230 color patterns, 25 base hues and gray scales extended by 6 tones (dark to very light) and 3 saturation grades (strong to slightly gray / brown). Loose gem stones are not set into jewelry settings but are in the natural, polished state. Gemstones are minerals, rocks or organic materials used in the production of all types of jewelry including rings. Diamonds are composed of carbon, rubies of aluminum oxide and others just as lapis and amber are rocks or organic materials. Loose gemstones may vary widely in price and stability but some like diamonds are consistent for decades. Sapphire, Aquamarine and Tanzanite are further examples of popular gems.
Loose gemstones are featured in blogs that include pricing information as well as grading and composition details. Gem Select offers a blog with a wide range of articles and information on loose gemstones as well as hard-to-find items.
