Wow! A true collectible...the last one. The silver work is expertly done by the Artisans of the Philippines who Marianna and Richard worked with closely as they designed over 12 years ago. The inlay work is exquisite; Sugilite, cultured sparkling opal and in the center is a huge 12mm designer cut checkerboard Rainbow Lavender Quartz. The overall length is 15/16" and although it will come sized, it is completely adjustable.
