A stunning combination of rare metals. Sintra is made from three separate rings. The pictured ring features two outer rings machined from solid from platinum 950 with a centrepiece made from 18 carat white gold. `
The three rings are permanently bonded together by a sintering process which allows the atoms of the metals to intertwine without melting.
Fine grooves are then machined into the ring using a specialised diamond tipped tool before the ring is hand finished.
It is available in any combination of metals except titanium.
