Description

An old round or mine cut, natural Diamond Ring 1.38cts in total, principal diamond 1.2ct N/O colour and set in platinum in a beautiful elegant setting. It has been beautifully cut and is a super stone and set in a really lovely setting possibly french from the early 20th century. Set with old round cut diamonds to each side, it comes with an independent diamond report. The ring can be sized to fit for the listing price, it is a very attractive feminine ring, delicately set but sturdy enough due to its materials to be worn everyday as an engagement ring. Total diamond weight approximately 1.38cts. This beautiful ring is absolutely stunning on and would make a fantastic engagement ring, it is really spectacular. I love these old cut diamonds, so individual in style and becoming increasingly collectable as they become rarer and more sought after. The table cut diamonds which are earlier have shot up in price over the past few years and I think the same will be the case for these lovely cuts, they are already going up in price so a really good investment and also very durable and perfect for everyday wear as the diamond is the hardest material known to man and this is why it is so suitable as an engagement ring.

FAQs

Old mine cut diamonds are characterised by a near-square or cushion shape, a high crown, a small table, a deep pavilion, and a large culet facet, typically cut by hand during the 18th and 19th centuries.

These rings were traditionally handcrafted using metals such as yellow gold, rose gold, silver-topped gold, and later platinum, often featuring hand-beveled settings and intricate pierced galleries.

Authentic pieces exhibit hand-cut facets that appear slightly irregular under magnification due to manual shaping, closed-back or foiled settings in older pieces, and signs of genuine age-related wear on the metal.

An antique ring pairs effectively with modern minimalist bands for a mixed-era stacked look, or worn alone as a singular statement piece against understated clothing.

Historic jewellery should be cleaned gently using warm soapy water and a soft brush, avoiding ultrasonic cleaners which can damage fragile settings or old stones.
