Shop from our extensive collection of blue gemstones, including blue sapphire, tanzanite, blue tourmaline, fluorite, blue zircon, iolite, lapis lazuli, turquoise, sky blue, Swiss blue and London blue topaz, and many more. Choose from various sizes, cuts, shapes and shades of blue. Blue gemstones are ideal for both men and women's jewelry designs and both fine and tribal style jewelry. From this page, you can filter the results further by using the left-hand menu. For instance, you can shop by gem type, shape or cutting style. Using the check boxes at the top, results can be narrowed even further by singles, lots, faceted or cabochon gems. By using the top menu, you can search by origin, carat weight, size, price and other factors, to enable you to find the exact gemstone that you are looking for.

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
