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 Octagon shape / Emerald-Cut, faceted and cabochon gems available now in 16 x 12 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 usually 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 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.

Me parece que la pagina es muy accesible para la compra y el pago ; solo tengoUna oportunidad de mejora seria que exista la opcion de recoger el pedido directamente en la sucursal de mensajeria porque en ocasiones casi siempre estamos fuera de casa. en general todo muy bien por el momento.Otra opcion de mejora es que existieran cupones de descuento y ofertas especiales , ya que una amiga y yo compramos frecuentemente gemmas para uso personal y a ella le comentaron que no tenian ningun descuento como cliente frecuente , esto lo pregunto previo a hacer este pedido .gracias !

This site is *amazing*! The vast selection is almost enough to make you giggle. Oh, wait…If you want it, it’s probably here. I’ve read some reviews saying it’s hard to use the search filters but I found the opposite to be true. In fact, it’s plain fun to throw different filters on and see what you come up with. I ordered a small stone to sort of try them out and, dang! I’m so thoroughly impressed that I think I found a new hobby. The stone I got was exact what was represented on the site. So much so that I had to really look to see the difference between the picture and the stone that I got. And the range of prices. Wow! From a few dollars to tens of thousands if you’re into like, Ruby’s, Emerald’s, Sapphire’s and other gems that make you drool. And the cuts! The shapes and cuts are just plain gorgeous!Honestly, I can’t possibly say just how happy I am with this purchase! Now… off to make another…
