Look ravishing in red with the 14K. Solid Gold Hoop Earring with Rubies and Pearls. Five rubies are set in the channels of each solid gold hoop. A pearl hangs from the hoop, and it is decorated with a marquis-cut ruby on each side. The classic combination of red and white is elevated here with the beauty of the semiprecious gemstones. The white pearl is luminescent and the rubies facets catch and reflect light. ***The natural rubies in this earring are not lab enhanced and may contain some variations in appearance due to inclusions. These variations result in a natural, unique beauty for each earring.
