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 Trillion 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 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!

I was looking for a cabochon multicolor labradorite stone, suitable for a pendant. I found gemselect.com & their computerized sort by price helped me find the stone i was looking for! Yes, I will come back when i am looking for gem-quality stones.

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!

Lo que me molesta un poco es que el envio rapido se cobra como tal de 2-3 dias, por lo que lo podrian hacer un poco mas economico y que sea un solo envio no dos opciones de envio, al comprar cierta cantidad de gemas o una cantidad de dinero podria ser gratis, es mi opinion, pero me encanto el sitio, mucha variedad y a buen precio perfecta para joyeria personal o regalos...

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.
