Some years ago I worked in the Los Angeles Jewelry District for a diamond dealer. All of our salesmen carried cubic zirconia samples for their own safety. The rings were 18K gold plated over either sterling or base metal, and set with czs, colored and clear. In stores these kinds of 18k gold plated Cubic Zirconia rings are quite expensive, but I bought them from my diamond dealer friends, I can sell them for much less and they really are exquisite. This ring is a gold toned love knot design, set with clear cubic zirconia - across both sides of the design. It is a Size 7. None of these rings have ever been worn - just carried around in sample cases, so the ring shank has no wear, and the stones are brilliant. These types of rings are great for those who like to wear jewelry when they travel or cruise, but don't wish to risk losing their real diamonds.
