December Birthstones
If you were born in December, you are lucky to have a choice of three gems on the modern birthstone list; blue topaz, turquoise and tanzanite. Blue is the color for December, and the traditional birthstone list also includes zircon and lapis lazuli. December has a range of blues as birthstones. Blue topaz is one of the most popular blue gemstones, with sky blue, Swiss blue and London blue to choose from. Large blue topaz gems are often affordable and cut in interesting shapes and styles. Turquoise has been used since ancient times. It is an opaque gemstone that is usually cut as cabochons, beads, carved or tumbled. Tanzanite is a relatively recent discovery that is found in Tanzania. It can be blue, violet or violet blue in various shades. Tanzanite is incredibly beautiful and quite rare. Blue zircon has great brilliance and is admired for its wonderful sparkle and teal-like blues.

In order to find the December birthstones that you require, filter the results further by using the left-hand menu. You can buy December birthstones by gem type, shape and color. By using the top menu, you can search by carat weight, size, price, origin and other factors, to enable you to find the exact December birthstones that you are looking for. All items are in stock and ready to be shipped.

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
