Katherine Jetter
An Exceptional Eye
As a fine jewelry designer, master gemologist, and founder of The Vault Nantucket, I create wearable pieces of art for bold and beautiful women. I'm known for my timeless settings, use of rare colored gems, and my ability to bring personal stories to life through custom designs and redesigns of existing pieces. Whether you're seeking a bespoke creation, a refreshed heirloom, or a signature design - from opal and pavé diamond orbit earrings to a dainty pink rubellite heart pendant - you're sure to find something beautiful and deeply personal here. K.J.Â
