The details
Deep red and round, this loose ruby is cut in a brilliant style that catches light from every side. It is a natural ruby, heat-treated, graded AA quality. The stone is sold on its own with no metal, so you decide how it is mounted. A jeweler can set it in a ring, a pendant or a pair of studs, wherever a small point of red fits your design. Pair it with a white metal for contrast or a warm tone for richness. A fitting choice for anyone born in July.
Key Features
