4mm crystals are set within a modern, rubover titanium setting - hypoallergenic so perfect for those who can't wear gold. To be used only in conjunction with the Studex Ear Piercing system in store so not available for home delivery. Sadly our ear piercing service is NOT available in Cambridge, Chelmsley Wood, Dartford, Dover, Gloucester, Lakeside, Newport, Nuneaton, Solihull, Stevenage and Waltham Cross so please do not reserve ear piercing studs online for collection from these branches.
