What is an old mine cut diamond?

Definition
The old mine cut is the earliest form of modern-style diamond cutting, originating in the 1700s and remaining popular through to the late 1800s when the old European cut gradually replaced it. It has a roughly cushion-shaped outline, a high crown, a small table facet, a large culet at the base and relatively few, chunky facets. Each stone was cut by hand to rough proportions guided by candlelight rather than electric light, giving old mine cuts a warm, intimate glow quite different from the crisp brilliance of modern cuts. They are prized for their historic character and romantic sparkle.
Frequently asked questions
- What does old mine cut mean?
- The name refers to the old diamond mines of India and Brazil from which most diamonds came before the South African discoveries of the 1860s. Stones from those early sources were cut in this cushion-based style, so the cut became associated with the mines of that era.
- What is the difference between an old mine cut and an old European cut?
- Both are antique cuts but the old mine cut is older and has a cushion-like or squarish rounded shape. The old European cut, which came later around 1890, is more circular and is the direct predecessor of the modern round brilliant.
- Are old mine cut diamonds valuable?
- Fine old mine cut diamonds are genuinely valuable and collectible, particularly in good colour and clarity. Because they were all cut by hand they cannot be reproduced, and their charm and rarity attract strong demand from antique jewellery collectors and people who want something with a history.
