Art Deco 2.59 Carat Old Cut Diamond Trilogy Ring, circa 1915

So, so impressive. This trio of old cut diamonds look utterly fantastic on the finger. The 1.06 carat stone in the centre is a shade whiter than the slightly smaller outside two. Each of the diamonds is held in six claw platinum “crown” collets, leading to beautifully detailed carved shoulders, to a slim yellow gold shank. Immense.
