Round Shape 7 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 Round shapes, facet cut and cabochon gems available now in 7 mm diameter 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 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 in the market for a replacement gemstone for a solitaire ring that I recently purchased. I was delighted to locate GemSelect as an option for the replacement gem. They have an impressive selection of gemstones! I ordered a citrine trillion cut gemstone. The pictures of the gemstones appear accurate in terms of color and size . The prices are appropriate for the quality of stones I've received. I will continue to shop with GemSelect and will recommend them to anyone in the market for gemstones.

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.

I fell in love with my beautiful blue turquoise stone. When I received the stone it is more beautiful than the picture showed. I can hardly wait to design my pendant!)

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
