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.

finally bought the last rock to complete my ring idea; needed another white one after giving the big diamond to my daughter. a diamond that size is out of my retired-school-teacher budget, so i bought a white zircon. went back to the same place that i got my loose sapphire-- great selection, good prices, good delivery!

I'm always real pleased with this website, I don't think there is much you could do to make it any better. I wish the shipping charges were lower, but it is understandable.

This is a site that sources valuable and genuine stones forms around the world, with and honest and descriptive sections, as well as specs, and the option to have the gemstone collection one might purchased—certified! Price ranges vary, but are always affordable and always worth it, whether it’s a gift, or for a personal business.

I am bored and shopping , it was fun

I recently found a site on-line where you can purchase faceted gems. I made one purchase, and the day the gems arrived, I was so happy with them, that I immediately went back on-line and purchased four more gems! They look better "in person" than they do on the computer screen. I am making purchases for gifts.

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
