John Hardy Lahar Ring – Dome in Silver with White Diamonds – Size 7
A new collection from John Hardy inspired by the untamed beauty and elemental forces of Bali’s volcanoes. Like lava, or “lahar” in Balinese, hits the oceans to create black sands, molten metals meet wild diamonds. Natural inclusions and flecks of carbonation give wild diamonds their undeniably unique color palette, ranging from icy grey to deep charcoal. Meticulously handset to maximize sparkle, an array of trilliant, kite, round and hexagonal cuts present a multifaceted scintillation of light. Pave & Flush White Diamond (0.04ct). Grey Diamond (0.52ct). Ring measures 5mm to 17.5mm wide.

How to measure your finger
Make sure the string is pulled snug (the tighter the better) to find your best fit.

With a pen or your other hand, mark where the string meets. Make sure it is pulled snug.

Lay your string against a ruler and measure the length (cm). This number is your finger circumference. Compare it to our size chart to find which size is right for you.
