Celebrity Engagement Ring: Katy Perry

We learned a new piece of diamond trivia after reading about Katy Perry’s engagement ring:  a rare diamond called “the Golconda diamond”.  India’s most prized diamonds were known as the “diamonds of Golconda,” and some of the most famous Golconda stones include the Hope Diamond.

 

The term “Golconda diamond” is still used today to indicate very high-quality stones. These diamonds must have a level of transparency and quality found only in rare, chemically/optically pure natural diamonds. The term “Golconda” is also used as a generic term to describe higher quality diamonds with an antique cut.

 

Ring Details: 3 carat Golconda diamond set in a vintage yellow gold band from Cartier. Estimated to cost $120,000
