Symbolizing strength, boldness and balance, the black onyx stone is a reflection of confidence and sophistication. Our black onyx gemstone stud earrings feature a round stone in a sterling silver prong setting and offer a brilliant touch to any look. Although the ruby is the most-often known birthstone of July, some traditions and earlier times recognized onyx as the birthstone for July. Onyx is also often given to commemorate the seventh and tenth wedding anniversaries. Wear solo or paired with other earrings for double piercings. Looks equally nice worn by men or women.
