Round Amethyst Gems
Crystalline quartz in colors ranging from green to pale lilac to deep reddish purple and ranging from transparent to translucent is known as amethyst. Value per carat in amethyst, unlike many gems, doesn't rise exponentially with weight as it is readily available in large sizes; but depends almost entirely on color. The "Siberian" deep purple with red and blue flash commands the highest prices. Green amethyst, new to the market, is produced by heat treatment.

Round amethyst gems are available in singles, matched pairs and gem lots. Round amethyst gems are perfect for any jewelry design, whether they are used as center stones or accent stones. Choose from various round amethyst gems in calibrated sizes. Use the search filters at the top of the page to find the perfect round amethyst gems by size, carat weight, price or origin. The tick boxes will direct you to singles, pairs, lots, faceted gems or cabs.

I have been ordering from GemSelect for at least 6 years. Every single order was perfect - every item was as advertized, in perfect condition and arrived well within the specified time frame. I have recommended them to several friends.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
