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.

Everything was right there - The site provided the exact minerals I was looking for. The search for items filtered easily, with results showing pictures of exactly what I bought, at reasonable prices. It doesn't get any better than this. Well, the shipping charges could have been lower, but they weren't outrageous.

Good: Your reputation of selling quality trusted gems is what encouraged me to buy from you in the first place. Without it, I would not have bought anything. I intend to test everything with a gem tester, but also will get privately appraised.Bad: My only gripe is the labs you use aren't the best. They're not very well known, and not readily accepted by the buying market in my opinion. Pending my gemologist appraisals, we'll see how well your assessment aligns with trusted IGS accredited appraisals.

I have been looking at the website for a few days, educating myself about Sapphires and other gems. I want to have earrings made as a gift for someone. I bought a air of gemstones for myself today. They look beautiful in the photo.
