Round Shape 5 mm Gems

How are 5mm Round Stones 'Used in Jewelry' and Worn?

GemSelect’s round shape 5mm gems are ideal for earrings, bracelets, necklaces, and rings and perfect for new designs or replacing lost or damaged stones. Our selections are available as single stones, pairs, and lots which make it simple to purchase based on your plans and needs. For colorful designs search our 'multicolored lots' that are hand selected for perfect color combinations. Whether you’re creating earrings, a ring, or a more significant piece you will be able to find the stones you desire.

What Stones are Available in GemSelect's Calibrated 5 mm Round Gems?

GemSelect’s precious and semi-precious gemstones are available at wholesale prices. Our 5mm round-cut Ruby, Sapphire, Peridot, and Aquamarine are famous for earings and look stunning in white gold settings. Ruby, Opal, Emerald, Garnet, and Peridot are choice stones in rose or yellow gold settings. Aquamarine, Sapphire, and Amethyst are stunning in white gold settings for any piece.

Are There Anymore Design or Gift Ideas?

Yes, there are! GemSelect's round stones can create remarkable pieces when combined in multicolor or single color rope bracelet arrangements. A 5mm precious stone can be stunning on its own when used as a pendant allowing the color of the gem to create the beauty of the design. For rings, we find a 5mm center stone in a three stone arrangement is beautiful. Sapphire engagement rings with a halo setting are also popular in this size. Our gemstone pairs make it easy to design an exquisite set of earrings which is one of the most popular uses of these stones. Earrings and necklaces in the 5mm size make fashionable birthstone and anniversary gifts too. You will find that the versatility of the 5mm round gemstone is endless.

I love gemselect and I have bought a fair amount from them. The only complaint I have is not being able to save gems. I have a lot of projects so i am in the market for a lot of different gems and it's so disappointing to have to delete them all just to purchase one or two that I have saved in my cart.

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
