The unique balance of the Tiare range
Launched in mid-1994, Piaget’s Tiare collection draws its inspiration from the structured geometry of historic tiaras. This pre-owned ring centres on an oval-cut diamond, estimated to weigh 0.30 carats. The gem is set in a bold 18K yellow gold setting. Identified by the reference PGG3410651, this piece of jewellery is characterised by a striking contrast between the density of the precious metal and the clarity of the gemstone.
Architecture and jewellery craftsmanship
The ring’s structure features a high density of solid gold, ensuring a balanced fit. The central oval diamond is secured by a half-bezel setting, a technique that blends seamlessly into the curve of the setting. On either side of this centre stone, a pavé of brilliant-cut diamonds unfolds across three distinct rows. These accent stones are set using a traditional grain setting, designed to protect the gems within the thickness of the gold alloy.
Why choose this second-hand ring
Acquiring this designer piece from the 1990s is a discerning and aesthetically informed choice. The quantity of gold used to craft this ring shank and the technical precision required for this curved pavé setting would represent a significant production cost by contemporary jewellery standards. This second-hand piece offers direct access to the craftsmanship of a Geneva-based workshop, with a bold, mineral and metallic presence.
