The details
Deep red and sharply pointed, this loose marquise ruby is a natural stone, heat-treated, with a faceted cut that catches light across its slim length. It comes as a single gemstone with no metal attached, so the setting is yours to choose. The marquise outline is narrow and elongated, which gives a ring or pendant a clean, graceful line. Set it in an understated band, or let it sit beside small stones in a cocktail ring. Ruby is the July birthstone, so it suits a birthday gift for someone born that month. Classic color, open possibilities.
