Oval Shape 18x13 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 oval shapes, facet cut and cabochon gems available now in 18 x13 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.

Completely would recommend this company to any gem collector, jewelry store, or someone looking for a gemstone to repair their jewelry. There is an abundance of choices at great prices! If you don't see what you need exactly the customer service department will go above and beyond to meet your needs. Shipping is very reasonable! The gemstones always arrive well before the expected arrival date. This company has very high standards of meeting their customers needs! They are the number 1 company I go to when looking for any gemstone. They are also very detailed in their descriptions so there is no confusion at all as what you are purchasing! Highly recommended!!!!

I was just browsing on my trusted gem site, Gem Select, when I saw gems that were my grand children's birth stones. The price was right, so I ordered them. I like to surprise my grand children with something special for their birthday, and they will be nice birthday gifts.

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...

this is my first experience with GemSelect so I can’t really comment on much more than the website & purchasing experience, which was great. there were a few stones I went to look at that didn’t really have descriptions about them (their properties or spiritual benefits for example) like some of the other stones & I thought that was interesting & I wondered why they didn’t. but all in all, the purchasing experience was easeful & I can’t wait to receive my gems & see if the quality is as beautyfull as they seem to be in the pictures.

I have found what I think is the best kept secret for buying stones, and I have to tell you about this gem stone site I found! There is a large selection of stones and crystals, and the best prices I have found for nuummite! They make it incredibly easy to find exactly what you are looking for by shape, size, cost, and clarity. I have already purchased two stones and I will be checking the site frequently from now on for everything and anything that I am hoping to find. They have individual pictures of every stone with different views so you absolutely know what you are buying.Honestly, I was hesitant to purchase something the first time BECAUSE the prices were so competitive and below anything I found elsewhere and because the stone was both being purchased online and from another country. I received the stone ahead of shipping schedule and when I received the package, it was in not one but two separate zip lock bags. One had the certificate of authenticity and details about the stone. The second had information about the stone itself. I was so impressed with the quality of the stone and that it was definitely the stone I picked out on their site, that I ordered another stone without hesitation. I will be using this site to purchase gifts for everyone I can think of! lol

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
