These butterfly-shaped stud earrings are made from 18 karat yellow gold with deep black onyx stones in a cabochon cut. Each prong-set stone contributes to the total carat weight of 4.25, making these oversized studs stand out when worn. The contrast between the yellow gold and black onyx creates a bold visual effect that draws attention to the unique moth design. These statement earrings combine the natural shape of a butterfly with the rich color of black onyx for a distinctive jewelry piece.
