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 13 mm x 13 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.

Everything was straight forward as always. I've shopped here many times over the years and know where things are. Everything was quick and easy to find. The website is organised well. Great shopping experience.

It was a nice and easy process throughout! The website is simple and well made I found everything I needed quickly. I needed some emeralds of a certain size for my custom engagement ring but they only had 3 available on the website, So bought the available ones and reached put to customer service to see if they have any more and they messaged me back within minutes with a list of similar sized emeralds that were not on the site! I quickly purchased my remaining emerald and they added it to my first order! I am more than pleased with the experience and I will be recommending them to anyone in the market for gems! 10/10

I've been collecting gemstones for a while now so I wad excited that I found a relatively cheap site to gems from. When I opened to package i was a little surprised and how small they were but it's literally marketed for jeweler's so I understand why my little square cut sapphire is the size of a crumb, but all in a ll I'm very happy with what I ordered.

After working with and polishing low-grade, rough fire-agate, only to be disappointed, this shop was nirvana. The costs of some gems might seem high, but I have easily spent the same amount rough polishing lousy material only to get a few hints of fire. If you want Fire-agates, BUY the agates you want. These are excellent specimens and are worth considering.
