Wow! A true collectible.! 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 exquisitely comprised of cultured sparkling opal in seep blue and green and in the center of the top portion we find a huge 8mm designer cut checkerboard Caribbean Quartz. The bottom portion features an 18x25mm Opalized Window Druzy pear surrounded by inlaid cultured opal. The overall length is 3 1/4".
