Amethyst fan? Then you really need to check out these 9ct yellow gold studs with genuine 3.5mm amethysts! The beautiful purple gems look stunning against the gold and are fastened with the Andralok system that simply clicks a lever in place with no fussy backs to lose. Although the pin width on these is a slightly thicker 1mm. An adorable size for any lobe piercing and special gift for February birthdays.
