The modern Nassak diamond was cut from a much larger stone originally housed in the Trimbakeshwar Shiva Temple in India. The change in modern tastes has resulted in the loss of approximately 53% of the diamond’s original weight. However, you can restore what has been lost to history with a precise replica of the historic Nassak diamond from The Stonecutter.

Nassak Diamond History

For over 300 years, the Nassak diamond graced the Shiva temple outside Nashik, India, but in 1817, the stone disappeared during the Third Anglo-Maratha War. Once it reappeared in the possession of Baji Rao III, the last Indian Peshwa prince, then Nassak was given in turn to British Colonel J. Briggs, Francis Rawdon-Hastings and the East India Company.

The East India Company sold the Nassak to Rundell and Bridge, a London-based jewelry firm that undertook the first cut to improve the diamond’s brilliance, reducing the diamond from about 90 carats to approximately 79 carats.

Beginning in 1831, the Nassak once again went through a number of ownership changes, being sold to the Emmanuel Brothers, then Robert Grosvenor, the 1st Marquess of Westminster.

In 1922, the stone was sold to French jeweler George Mauboussin who was living in the U.S. It was on American soil that the Nassak diamond was subject to attempted robbery—twice! The Nassak diamond was featured at the 1933 World’s Fair in Chicago.

Famed American jeweler Harry Winston bought the Nassak diamond in 1940 and had it cut to its present form: a 43.38-carat emerald cut. The stone was purchased by Commander William Bateman Leeds, Jr. who presented the stone to his wife as a sixth anniversary present.

The last known owner of the Nassak diamond was Edward J. Hand, a trucking firm executive who purchased it at auction in 1970.

Making the Nassak Diamond

The Stonecutter invests great care into the research of each diamond to ensure the most accurate replica. However, there is only one reference to the historic Nassak diamond (Bauer), but the facets cannot be cut as shown in the drawing. For instance, the drawing shows parallel lines that create a single horizontal facet, but such a horizontal facet is mathematically impossible. The replica is created with a slight taper that results in a split facet. The adjustments do not significantly alter the stone’s appearance, but it is one of the few instances of a replica differing from the historical data.
