An 11.04 carat rectangular octagonal black spinel with 0.20 carats of round white zircon in 18K yellow gold over sterling silver ring measuring approximately 0.53 inches long by 0.90 inches wide - the black spinel cocktail ring in warm gold. At 11.04 carats in a large rectangular octagonal stone, the black spinel has commanding presence on the hand. The warm gold creates the high-contrast frame that black stones perform best against. White zircon accents add brightness. Not sizeable.
