Octagon Shape 18x13 mm Gems

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 18 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 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 was led to the site by google when looking for specific green sapphire briolette. Site is well laid out and very easy to purchase from. Hope the stone is as satisfying!

I love the variety of stones available, and especially that I'm not buying from a stock image -- the stone I see online is the actual one I'm getting.

I ordered peridots online and they were very close to the shade in the photo. They had a good polish and pretty good lapidation for a commercial cut. They had the correct critical angles for the ri of the material so that the stones had life in them. The down side was the lack of tracking and the length of time that it had taken to get them.

This business makes it easy to research and find all pertinent information about the individual gemstones and other information such as the recommend use (ring or pendent for example). Also it's important to know about things like hardness and durability of the gemstones. I also appreciate the history of purchases and transaction details. Just be sure to register on the website to get the best experience.

So many stones, so little time and money. Easy to fill up the cart when the stones are beautifully pictured. I hope the real items are as beautiful.
