Bursting with brilliance and showered with the beautifully wearable blues and purples of the horizon that inspired them, the crystal accents on this necklace are as unique as constellations. Our passion for artisan crafting is reflected in the time-intensive hand-setting of each adornment. This Monarch butterfly features tanzanite/blue fine European crystals. Our silver items have a protective lacquer finish to help prevent oxidation. To care for our silver items, simply wipe down your pieces with a dry, 100% cotton cloth. Keep them away from water, jewelry cleaners, silver cleaners, treated polishing cloths, perfumes, hairspray, lotions, hand-sanitizers and make-up. We offer our own that you can safely use.
