You rarely see faceted Lapis, particularly of this exceptional quality, due to the amount of waste in the process. Similarly, the color is an uninterrupted deep royal blue, lighter and more saturated than the typical navy Lapis.
The value of this piece far exceeds the price. 18 inch graduated beads. Sterling clasp and 2 inch extender chain. I bought this necklace from the lapidarist that made it and was retiring from jewelry making. He only made one of these because he could not recover his costs.
