A PAIR OF DIAMOND AND COMPOSITE RUBY EAR CLIPS, BY MICHELE DELLA VALLE
Each centering upon a circular-cut composite ruby, within a pavé-set diamond surround, accented by circular-cut rubies, mounted in 18k white gold
With maker's mark for Michele della Valle
With report CS 40456A and B dated 24 February 2009 from the American Gemological Laboratories stating that the two larger rubies are composite rubies. They have been heavily treated using a high refractive index lead-glass to fill fractures and cavities, vastly improving the apparent clarity and potentially adding weight. The glass may be damaged by a variety of solvents. Stability: Good to Fair
