Understanding the Old Mine Cut Diamond

In the 18th and 19th centuries which is when we see the first Old Mine cut diamonds. At that time, modern cutting machines did not exist, so each stone was handcrafted. Thus,  every Old Cut Diamond is a single of it’s kind.

Unlike what we see today with diamonds cut for maximum brilliance using modern technology, the old mine cut diamond was designed to glow at candlelight. This gives it a soft romantic quality as opposed to a sharp sparkle. 

History of the Old Mine Cut Diamond

The old cut diamond, which is what we think of as a heritage diamond, began in the Georgian and Victorian times. At that point, the primary source of diamonds was outside Brazil and later from early South African mines, hence the term “old mine cut”.

Because cutters used to work with basic tools, they would shape diamonds out of their natural crystal structure. Which in turn would produce stones that are very much at risk and full of character.

Many royal and noble families preferred Old Cut Diamonds and had them put into their engagement rings, brooches, and also in heirloom jewelry, which has been passed down through the generations.

Shape and Appearance of an Old Mine Cut Diamond

Old mine-cut diamonds are known for their pillow-shaped face. Also, they may not be symmetrical, which is a characteristic that appeals to the antique collector.

Key visual features include:

• A square or rectangular cushion shape
• Rounded corners
• A premier crown (top of the diamond).
• A deep pavilion (bottom part)
• A large bottom facet.

These elements present the Old Cut Diamond in a bold and soulful way instead of a sharp and flashy manner.
