Gem FAQ's

How can I judge the value and quality of a gemstone?
Simply put, the type of gemstone and color you select should be the one you like the most, the one that will give you the most pleasure to wear. However, colored gemstones are judged by their beauty and rarity.
The same "four C's" that establish quality in diamonds are used for colored gemstones. cut, carat, weight, clarity and most important , color.

Color: The more pure and vivid the color, the more valuable the gemstone.

Cut: All gemstones must be cut well to attain their maximum potential for beauty. Quality cutting is what produces the brilliance and scintillation that captures the eye of the beholder.

Clarity: Gemstones contain characteristic inclusions that provide proof of their natural origin. Those inclusions should not be so visible that they detract from the beauty of the gemstone.

Carat Weight: Obviously, larger gemstones are more rare. However, some gemstones, such as Amethyst and Tourmaline, routinely occur in very large sizes while others, such as Ruby and Sapphire, rarely occur in sizes above 2 to 3 carats.
