Italian Art Deco certified unheated sapphire platinum ring

DESCRIPTION

An Italian Art Deco platinum ring set with a certified unheated transitional cut sapphire from Sri Lanka. The sapphire is decorated by 10 rose cuts diamonds with total estimated weight of 0.15ct. The dome shaped structure of ring showcases the architectural beauty of Italian jewelry.

Transitional cut means the cut of stone is transitioning from old European cut to modern cut. The table of gemstone is relatively small compared with modern cut stones. The good quality vibrant sapphire is a strong contrast to the bright color platinum and diamonds which also adds more charm to the piece.

This ring is supplied with a detailed certificate from R.A.G., an independent gemological laboratory in Italy, dated first June of 2021.
