Product Description:

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 Octagon shape / Emerald-Cut, faceted and cabochon gems available now in 12 x 10 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 usually 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 round shape settings will allow 0.3 mm or slightly higher even. This small variance can usually be accommodated for most 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.

I love the clear description of the certification options. It's very rare to see a gem site that offers a deep explanation of each institution that would certify the stone(s).

Fantastic dealer for quality gemstones. Website is easy to navigate, selection is superb, delivery of purchases is prompt. Easy to select incorrect payment options, however.

I placed order#384714 based on the picture on your website and the stone came in much darker. I'm sure it's the same stone i ordered but your lighting made it seem a lighter blue. I was trying to match a stone for a customer and based on the picture it would have been close enough but the stone in person is a mile off.

was just windowshopping and spotted a couple "Very Uncommons", a tsavorite & a demantoid garnet that were both in a size I was looking for, & that I could very easily pay for -- so figured I would grab the tsavo ASAP and got the demantoid to accompany so they wouldn't be lonely.
