Trillion Shape 8x8 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 Trillion shapes, facet cut and cabochon gems available now in 8 mm x 8mm 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.

The Ruby Zoisite bird is beautiful and will delight my sister, I hope, for her birthday in July. I, personally love the stone which is within her ruby birthday stone, and the bird appears beautifully carved.

Gemstones are accurately portrayed and comes with a gemologist confirmation of authenticity (not appraisal) but still helps when I set in my settings to make and sell rings.

I would recommend gem select. They care about all details from description to quality to packaging to shipping. I specialize in turquoise so I would like more explicit provenance than "American"... Couldn't they give me mine or at least state? Never the less very classy. Also, their turquoise cabochons are very thick for good and bad. I cut many in half to make them more versatile and commercially useful. If one can't do that then you are going to have to settle for wire wrapped jewelry. I think that overall thy are a great resource.
