Trillion Shape 14x14 mm Gems

Some people by gems by color or price, but for many, it is best to buy gems by shape and size - especially if you're in need of a gem to replace a previous item that was lost or damaged. Calibrated Trillion shapes, facet cut and cabochon gems available now in 14 mm x 14 mm size range. Shop a wide range of calibrated gemstones by size online at wholesale from GemSelect.

As a general guideline, when it comes to 'calibrated' gems, they are not meant nor expected to be cut to exact measurements. For calibrated gemstones weighing under one carat, most jewelry settings will accommodate a gem which is within 0.2 mm of the calibrated size in order to fit a standard setting. For gemstones that weigh over one carat, a larger variance is acceptable, often around 0.3 mm or slightly higher even. This small variance can usually be accommodated for standard style settings. Round-cut gemstones should also have a greater variance in acceptable size when it comes to calibration; in fact it is usually possible to mount a round stone of any size in the closest standard setting.

Very good value for the money. Great pictures that can be enlarged. Length and Width and carat size, and several angles that the gems can be viewed. Some of the gems have videos!

I fell in love with my beautiful blue turquoise stone. When I received the stone it is more beautiful than the picture showed. I can hardly wait to design my pendant!)

My significant other told me about gem select, he knows I have a small business in making jewelry. I often use these and experiment with new designs and seeing the wide variety of options really is amazing. I love all of the items I see, but sometimes I want more than one of the selection and there is only one of that type. I understand it takes work to put these together so I am not complaining. I would recommend this sort of thing to my friends that might be interested in making jewelry or to others that are on forums say on reddit or other sites.

I love looking at gems. Your site is very easy to navigate and to find what I'm looking for. It is also very easy to explore lesser-known gems that are not always easily found. I spend way too much time exploring! LOL

An incredible selection of gemstones at a wide range of prices. Some fantastic cuts - unlike any I have seen anywhere. Ita's fun to look even if there is no intention to buy - if you can resist

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
