Bicolor Gemstones
Gemstones can often have more than one color in a single stone. Gems that are two colors are known as bicolored gems, and these include ametrine, which is a mix of amethyst and citrine in one stone, giving it both violet and yellow colors. Other bicolored gemstones include tourmaline, ruby in fuchsite and more. We have bicolored natural gemstones in various colors, shapes, cutting styles and sizes. From this page, you can use our filters at the top or on the left-hand side to find gems by gem type, color, shape, cut and so on. For example, select 'ametrine' to see all of our bicolor ametrine gems. You can also filter by single, pairs, lots, faceted gems or cabochons by using the check boxes at the top.

I love GemSelect, personally. I browse their site almost daily to see all the new stones available. Their selection is pretty amazing. The quality isn't always the highest and the cut of the stones isn't always perfect. But for the price, and if you look hard enough, you can find a real gem, so to speak.

I would recommend to a friend because of the quality of the products purchased. The gemstone quality is very high and the gems purchased are beautiful. Any friends interested in having custom jewelry made would definitely be recommended to the site. Also, every shipment is handled with care and I am very pleased with that.

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
