Solasfera Diamonds

Our pursuit of brilliance led our founder David S to develop and patent the famed Solasfera range of diamonds, which produce such radiance that they are named after the Italian term for "sunsphere". 

Fewer than 0.01% of raw diamonds meet the requirements to be considered for a Solasfera cut, and then only a handful of master cutters around the world are qualified to make the demanding cuts to create the diamonds.

Solasfera diamonds are available in the following shapes:

  • Round cut — The acclaimed round cut Solasfera diamond features a stunning 91 facets arranged in an optically perfect design.  Round cut Solasfera diamonds are prized by collectors because they delivers significantly better flash and fire than conventional  57-facet "hearts and arrows" ideal-cut diamonds.
