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 10 mm x 5 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 wanted to buy some gems because I think they’d be cool to have and this seemed like the best website to buy them from. The website is a bit old looking and could use an update to the user interface but otherwise it’s great.
Overall Rating -> 10 
Great selection, the user interface was somewhat irksome. If there was a way to filter out specific items (I.e. particular treatments to the gemstones), or would greatly improve the site. Otherwise, great!

I’ve purchased from GemSelect a few times in the past year. I would not shop anywhere else. The photos make all the difference…I can select the exact color I want. I have over 100 pieces, and I’ve never been less than thrilled with each gemstone.

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.

Good: Your reputation of selling quality trusted gems is what encouraged me to buy from you in the first place. Without it, I would not have bought anything. I intend to test everything with a gem tester, but also will get privately appraised.Bad: My only gripe is the labs you use aren't the best. They're not very well known, and not readily accepted by the buying market in my opinion. Pending my gemologist appraisals, we'll see how well your assessment aligns with trusted IGS accredited appraisals.

I was looking for a gemstone called Sphene/Titanite and found it on GemSelect. They had many gems to choose from and had good prices. I received my order a little later than expected but given that it's coming from overseas I wasn't too worried. The 2 gems I received are beautiful. I have to say that I have no gem knowledge- I am a novice and I ordered the Sphene for healing purposes, so I am hoping they are real. I have no way of confirming if that is true. But they are beautiful!
