Bi-Color Tourmaline
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 tourmaline gemstones. Tourmaline is a gemstone that occurs in almost every color of the rainbow, and may have two or more colors in one stone. Another popular tourmaline variety is 'watermelon' tourmaline, which displays three colors in a single stone. We have bicolored natural tourmaline gems in various colors, shapes, cutting styles and sizes, for example, scissor-cut octagonal bicolor tourmaline. From this page, you can use our filters at the top or on the left-hand side to find gems by color, shape, cut and so on. For example, select 'baguette' to see all of our baguette-shaped bicolor tourmaline gems. You can also filter by single, pairs, lots, faceted gems or cabochons by using the check boxes at the top.

finally bought the last rock to complete my ring idea; needed another white one after giving the big diamond to my daughter. a diamond that size is out of my retired-school-teacher budget, so i bought a white zircon. went back to the same place that i got my loose sapphire-- great selection, good prices, good delivery!

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
