Blue Sapphire Birthstone Stackable Ring

September's sapphire is the velvet blue of a sky just after sunset, and it is one of the hardest stones you can put on a finger, second only to diamond. That toughness is exactly what a stacking ring wants. We seat it flush in a slim band so it shrugs off the day and still layers neatly. One for a September child, or the cornerstone of a family stack. Cast to your size.

From $949 in the starting metal shown. Metal choice sets the final price; every ring is solid precious metal, never plated, and is made to her exact finger size to order. Building a stack or want a birthstone you don't see set this way? Ask our concierge and we will quote it plainly.
