Square Shape 4x4 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 4 mm x 4 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 love that I was able to find a site that offers REAL gemstones. I love the pictures provided of the gems so I can look at each one from different angles, I love the variety of gems on the site & I love the ability to narrow down my search to look at certain gems that fit my criteria.

My experience with gemselect was awesome so far. I had a few questions about their website and making orders and they replied quickly and were happy to help. I have not received the items I ordered yet as I just ordered them this morning. Although, I truly feel I am going to be a very happy customer once I do receive my items. Gemselect guarantees all their items and have a great return policy just incase. The have a vast selection of all kinds of stones and not to mention their prices are much better than some other websites. Thanks Gemselect I’ll be doing business here from now on!

Great selection. Love the many learning features like articles and gem information. Prices competitive for natural stones. I do miss not having a selection of lab-made stones, CZ’s, etc, which are useful when price and cost are factors.

Size and Weight

Gems are always measured in Millimeter (mm)

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

Note: 1ct = 0.2g
