This 18K rose gold Melissa Kaye Aria Skye diamond ring is cast in the United States and features two open-ended rows of 1.93 carat white diamonds cast in rose gold. This style is designed to wrap comfortably around the finger. You can, in theory, add hydrogen to graphite to make a new arrangement of carbon atoms that resembles a diamond. So, for the would-be Rumpelstiltskins of the world, you may not be able to turn straw into gold, but you can, it seems, turn a pencil into a diamond. But we've never been one for chemistry, so we'll take this Melissa Kaye ring instead.
