Trilogy Ring w/ Tanzanite
Three stones, one story. At the centre of this Trilogy Ring, a 0.45 carat oval tanzanite glows in its unmistakable blue-violet hue - a colour play reminiscent of the transition between evening sky and the deepest night. Two pear-shaped tanzanite accent stones (2.5 x 4 mm each) frame the main stone symmetrically, amplifying the celestial depth of the design. The tanzanites were sourced through an Indian intermediary, where they were also cut. A ring that makes rarity wearable. Crafted in 925 sterling silver with germanium for enhanced tarnish resistance.
