The perfect bangle is sterling silver with three 3.25mm orange sapphires set with 14kt yellow gold bezels. Two sapphires are set in the ends of the open bangle and one is in the middle of the bangle, that way no matter which way your bangle turns you'll see sapphires. It can also be adjusted to size as needed on a bracelet mandral. It is currently a size 7.5, but specify at checkout if you need it lager.
