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 marquise shaped facet cut gems, gemstone carvings and cabochons available in 14 mm x 7 mm sizes. For the largest selection of colored gemstones, Shop GemSelect Online.
As a general guideline, when it comes to calibrated gems, they are not usually expected to be cut to exact measurements and specifications. But rather, they're cut with slight variance in size, though the close approximatation in size is not clearly defined, there are general guidelines for what is considered acceptable. Obviously larger and heavy carat weight stones allow more room in size for variance, while smaller stones may leave little to none. This means a large 30mm calibrated gemstone, could actually be closer to 31 millimeters. For this reason, we recommend to always view the exact size in addition to the calibrated size details. The exact size will inform you of the variance you can expect. Some setting styles are more flexible with variance, such as prong settings, while other styles of mountings may need almost an exact size to the fraction of millimeter.
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 love the selection. My only issue os that the stone are not really calibrated, which means work with setting them.

No comment other than can you add more beads or drilled spheres to your inventory. Finding high quality beads on the internet is almost impossible. Buying from your site i fell confident what i am getting is real.

found what looks to be an incredible boulder opal on gemselect.com. Also got a bit carried away and bought more gems than anticipated. It's expensive to pay for these stones in this way, but the convenience makes it worthwhile.

If you want a gem that you can trust to not be treated, or if it is it's disclosed this is the place! There's something for everybody. I really like knowing that the picture of the item is the one I'm buying, not a sample or stock photo. If you make jewelry, buy gems here! You can even buy a gem and have it set by a jeweler. Again, they have an amazing inventory, and prices are more than fair. You won't be disappointed! I just wish they sold uncut gems. Sometimes I just want a specimen in the crystal form. I'm surprised they had no quartz from Arkansas, but they have a great selection of anything I've ever looked for.
