To sum it up, you can trade in chipped stones, but you normally get very little or nothing for them. Usually I tell people to keep their trade-in, and remount it into a pendant or ring or some other kind of jewelry. Keep your ring if it’s not worth much and just see if the jeweler will bargain on the sale price of the new item more. For any Shane Co. diamond, ruby or sapphire you have mounted in a ring, as well as any stud earrings or solitaire pendants you purchase, you'll receive the full value that you paid as credit toward the purchase of any other gemstone of greater value. Mondiamo provides a guaranteed, sight-unseen offer range for any diamond jewelry containing at least one natural, untreated diamond weighing 0.45cts or larger, with I1 clarity or better. The diamond must be accompanied by a third-party diamond grading report from GIA, IGI, GSI, AGS, HRD, EGL (USA) or IIDGR.
