Moonstone Half-Eternity Ring
- Regular price
- $150.00
The Moonstone Half-Eternity Ring features a delicate row of petite moonstones set across the front of a slim silver band. Each approximately 2 mm stone reveals a soft blue-white glow that shifts subtly with the light, creating a refined half-eternity design with gentle, continuous shimmer.
Crafted in 925 sterling silver, the ring has an approximately 1.6 mm band width and weighs around 1.65 g. Its slim profile makes it easy to wear alone or stack with plain bands, pavé rings, and other gemstone styles. As moonstone is a June birthstone, it also makes a thoughtful June birthday or anniversary gift.
