Mondrian Interlocking Rings. Tourmalines in rose pink and deep green, edged with diamonds, set in palladium and 18ct yellow gold. A bed of diamonds sits beneath the green tourmaline to be revealed when the pair of rings are drawn apart.

These rings are precisely engineered to interlock into different positions, giving you five ways to wear them.

Shown here: 18ct yellow gold, palladium, green tourmaline, pink tourmaline and diamond.

Available in: White, yellow or red gold, platinum or palladium and a range of precious stones.
