Round Shape 3 mm Gems

How Does 'GemSelect' Sell Round 3 mm GemStones and How can They be Used?

GemSelect’s Round Shape 3mm gems are useful in many designs for small jewelry and convenient to purchase due to their calibrated size and our extensive selection. For design ideas we suggest; Fiore Stud earrings, Sapphire Drop earrings, Tower Style earrings, Stationed Bezel Set bracelets, Pave Set Pendants and Rings all to be crafted using this size gemstone. They're also great for a minimal pair of earrings like Studs and can accent a larger piece of jewelry too. In addition to all the 'new designs' one can create with our 3mm round stones they're also ideal for repairs and replacement. Our single stones, pairs, and lots in this size range from 2.9mm-3.1mm.

Great selection. Love the many learning features like articles and gem information. Prices competitive for natural stones. I do miss not having a selection of lab-made stones, CZ’s, etc, which are useful when price and cost are factors.

Size and Weight

Gems are always measured in Millimeter (mm)

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

Note: 1ct = 0.2g
