A history of inheritance

The revolutionary Athena ® Diamond Cut originates from Antwerp, Belgium, from the De Belder family who are in the diamond trading business ever since 1875.
Athena ® Cut differs from the single focus of traditional rounds, its unique S shape showcases ‘Entwined Fiery Hearts’™ visible to naked eyes. This is the first time ever for a Belgian cut ‘dual-core’ diamond to be introduced.

In 2006, Matrix was invited to cut the huge rough (603ct) and thus created the world legend ‘Lesotho Promise’, which was later presented in Belgian EU Pavilion in 2010 Shanghai Expo as the ‘Best Piece’.
