Calibrated 7 x 7 mm Trillion Shape Loose Natural Gemstones from Ge...

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 7 mm x 7 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.

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.
