GIA-Certified 4.02ct Internally Flawless Cushion Cut Diamond Pisa Ring
$180,000
An exceptional engagement ring is centering an antique cushion cut diamond that is GIA-certified as 4.02 carats, G color, and Internally Flawless. The center diamond has a very unique spread and has a fascinating cut. Around the under-gallery of the diamond and along the shank are micro-pave diamonds. This ring is entirely made of platinum.
A copy of the GIA certificate is available upon request.
The center measures 12.67mm x 10.97mm x 3.41mm.
If you have any questions about the Pisa ring, please feel free to contact us.
A Word from the Jeweler: The prong placement on this cushion-cut diamond gives it a distinctive look that sets it apart from traditional settings. I also appreciate how the diamond accents along the outline add an extra layer of brilliance without overwhelming the design.
