4 mm Blue Moonstone Necklace, Prong Solitaire

For a cooler, more crystalline kind of moonlight. This 4mm blue moonstone solitaire glows with a clear, icy-blue sheen that feels quietly modern.

A natural blue moonstone is set as a neat 4mm solitaire, its transparent body carrying a soft, floating blue adularescence that reads fresh and contemporary next to rainbow moonstone's milkier glow. Crafted in 14K white, yellow or rose gold and platinum on an adjustable 16 to 18 inch chain, its refined scale layers effortlessly and wears every day. A distinctive alternative for the collector who already knows moonstone.

A thoughtful gift. A refined June birthday gift for someone who wants a rarer, cooler-toned take on the moonstone story.

The blue moonstone is natural and untreated and softer at about 6 to 6.5 Mohs, so wear it with care and store it separately.
