Black spinel with pear and round cuts in 18K yellow gold over sterling silver creates bypass hoop earrings where the gemstone's deep black - a natural mineral black with genuine luster, different from the flat darkness of dyed stones - meets warm gold for a bold black-and-gold color combination. Black spinel is a genuine gemstone with high refractive index that creates the rich, glass-like depth that makes natural black stones so compelling. At 1.86 total carats in two cut shapes, the earrings have generous stone coverage with both the pear's directional character and the round's consistent sparkle. Bold, contemporary, genuinely gemstone.
