Art Deco Old Mine Cut Diamond and Sapphire Ring

Description

This is a stunning Art Deco old mine cut diamond ring in platinum, finished with sapphire and diamond shoulders. This elegant Art Deco ring dates to the 1920s–1930s and works beautifully as an engagement ring, anniversary ring, or statement piece for everyday wear.

The impressive centre diamond weighs approximately 2.4ct with SI1 clarity and I colour. In addition, the shoulders hold around 0.22ct of calibre-cut blue sapphires and approximately 0.24ct of additional accent diamonds. The ring comes with an independent certificate for peace of mind.

This rare antique ring suits someone who loves bold Art Deco design, clean geometry, and timeless craftsmanship. It also makes an exceptional choice for engagements, milestone anniversaries, or collectors of period jewellery.

Diamonds are the traditional April birthstone and symbolise strength and lasting love. Meanwhile, sapphires represent loyalty and wisdom and serve as the September birthstone, which adds extra gifting appeal.

Design & Craftsmanship

This fully certified ring showcases classic Art Deco architecture with strong lines and balanced proportions. The old mine cut diamond sits proudly at the centre, secured in a refined setting that allows light to enter from multiple angles.

On each side, rich blue calibre-cut sapphires taper neatly into diamond-set shoulders. As a result, the design draws the eye toward the centre stone while keeping a sleek, streamlined profile.

Delicate openwork beneath the setting lightens the look and improves comfort. In addition, the finely set side diamonds add soft sparkle without overpowering the main stone. The slim band keeps the focus on the stones and makes stacking easy if desired.

Why We Love This Ring

This Art Deco old mine cut diamond ring combines presence with elegance. The old cut offers character you simply do not find in modern stones. At the same time, the sapphire shoulders add depth and contrast. It feels substantial on the hand, yet it remains refined and wearable. Overall, it’s a timeless Art Deco design that works just as well today as it did a century ago.

Styling & Versatility

Wear this as a striking engagement ring or let it shine as a right-hand statement piece. It pairs beautifully with a plain wedding band, however it also works with slim diamond or sapphire stackers. Because of its clean lines, it transitions easily from day to evening and suits both modern and vintage wardrobes.
