Signet Rhombus Garnet square
The signet ring, for centuries a mark of authority and belonging - here reduced to its geometry. In place of the engraving plate sits a 1.87 carat spessartine garnet in a carré cut, set on point in a plain bezel. Its deep brick red is among the most intense tones the garnet family produces. The ring head is faceted: clean planes run from the setting to either side and meet above the shoulders in a ridge that carries the rhombus of the stone on through the metal. The garnet comes from Morogoro, Tanzania. The band is 6 mm wide, the profile measures 1.7 mm. For him and for her. Crafted in 925 sterling silver.
