Black onyx cut to a four-leaf clover and ringed with a fine beaded gold border. At 10 mm these are the small ones in the range, which is the point: they sit flat to the ear, they do not swing, and they go on in the morning and stay there.

Black is the version that does the most work. It reads as jewellery against every skin tone and every colour of clothing, it goes to an office and to dinner without being changed, and the beaded gold edge keeps it from looking severe. If someone owns one pair of studs, this is the shape they reach for.

Athena Designs lists the size as 10 mm and the finish as gold plating, and has designed and curated fine fashion jewellery in Los Angeles since 2000.
