Square Shape 13x13 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 Square shapes, facet cut and cabochon gems available now in 13 mm 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 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.

I like to use GemSelect for finding calibrated sizes of gemstones. I purchased sapphires a few years ago and found the quality to be outstanding so I went ahead and purchased some more today (different) and some really unique moonstone. I'm opening a jewelry busy soon and so accurate gemstone sizes, quality, and reliability as a supplier is really important to me. Gemselect seems to fill all those requirements.

As long as I continue to have confidence that what I am buying is genuinely what is being advertised then I am happy. If an item is listed as natural but is actually lab created, well that would be the last time I support this company.

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.

I like the search ability. I was looking for a gemstone of particular size and color to place in a ring that I already have. Your company carries a large variety of beautiful stones.

Dimensions are given as;
length x width x depth,
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
