Square black spinel with 0.06 carats of round white zircon in solid 10K yellow gold stud earrings with 1.60 carats total measuring approximately 0.25 inches long by 0.26 inches wide with push backings - the black gemstone stud earring in genuine fine jewelry gold. Black spinel is a natural gemstone with a genuine vitreous luster that gives it depth and surface quality that black CZ cannot replicate. Set in solid 10K yellow gold, the deep black stones create a high-contrast combination with the warm gold that is simultaneously bold and refined. White zircon accents add brightness. Accent stones primarily zircon.
