Calibrated Heart Shape Gemstones 11 x 11 mm size from GemSelect

Some people by gems by color or price, but for many, it may be better to buy gems by size - especially if you're in need to a gem to replace another previous item that was lost or damaged: Calibrated heart shaped facet cut gems and cabochon gems in 11 x 11 mm size. Buy a wide range of calibrated gemstones by size 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.
