What is EX3 Diamond known for?

It is a jewelry retailer focused on fine pieces: diamond and moissanite stud earrings, pendants, rings and bridal sets in solid gold. Moissanite studs in 14k white gold are among its most recognized items.

Are EX3 Diamond's diamonds natural or lab-grown?

The store sells both natural diamond and moissanite pieces, so check the stone listed on each item. Moissanite is a distinct gemstone, not a diamond, and is graded differently.

Does EX3 Diamond offer a warranty?

Coverage depends on the item and is set by the store, so confirm the terms before ordering. Keep the certificate and receipt for any diamond piece, since they are usually needed for service or claims.

What should I check before buying moissanite stud earrings?

Confirm the metal karat, the total carat weight and the stone size in millimeters, plus the earring back type. Ask whether the stones are graded and whether a certificate is included.

Can I return an EX3 Diamond purchase?

Return windows and conditions are set by the store and often differ for earrings and custom or resized pieces. Read the policy on the item page before you order.
