Oval Shape 16x12 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 oval shapes, facet cut and cabochon gems available now in 16 x 12 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.

Through my Gemology course at OSU, I found this website and thought it's layout was appealing, as well as the amount of gems that are offered. Purchasing one was easy and simple, and I'll most likely do it again some time.

I make wire wrapped pendants for birthday presents, and always feature a birthstone as the base for the project. GemSelect has a wide variety of shape/size pieces to fit any budget. A detailed description of each individual stone is perfect for those searching for particular stones for their application, and information on stone treatments and the like are phenomenal.

It's important to understand what you are buying. Gem stones all vary significantly and you need to adjust your selection based on purpose, cost, expected out come.In my case I was selecting and very attractive heart shaped stone which once set in a pendent would fall in a specific cost range yet present an attractive picture of luxury without extreme risk e.g loss.

except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size
