TUBA is a timeless yet modern classic: a handcrafted engagement ring featuring a 1-carat round brilliant diamond, set in an elegant six-prong Cathedral setting that gives the stone both presence and space to shine.
Finely set pavé diamonds in a French setting line three-quarters of the band, creating a seamless transition to the center stone – resulting in a continuous, radiant sparkle.
Delicate claw prongs hold the diamond securely in place without distracting from the design – refined and precise. This setting enhances the visual size of the center diamond and highlights its brilliance from every angle.
The band width is geometrically proportioned to the center stone, giving the ring a sense of balance and modern clarity.
Crafted in platinum – a pure, tarnish-resistant metal known for its durability – TUBA unites timeless elegance with responsible values.
All diamonds are sustainably lab-grown under controlled conditions – a conscious choice without compromise.
This design is named after the first client who placed her trust in us. Her ring became the inspiration – and the origin of this meaningful creation.
An engagement ring with a 1-carat brilliant diamond and pavé-set accents – handcrafted in platinum, fully customizable, and rich in meaning.
