It is not necessarily true that a diamond is real if it cuts glass. Before the advent of high-quality synthetic gemstones, attempting to scratch a piece of glass with a gemstone was a more accurate way of determining whether it was a real diamond. However, some human-made stones are now hard enough to produce scratches on glass, just like diamonds. As a result, experts generally say that the best way to tell if a diamond is real is to have it inspected by an experienced jeweler, dealer or appraiser. Shop a large collection of diamond jewelry on 1stDibs.
