The term “Old Mine” refers to all antique diamonds that were cut by hand. One of our gemologists, Bryan, describes this process for us:

“Antique stones were cut by hand using a wedge cleave and hammer. As you can imagine, no two cuts were identical making all diamonds as unique as snowflakes. This style of cutting diamonds has been used since the end of the 17th century. Unlike today, there were no established standards that had been agreed upon, so a cutter held all the power as to how he would bring out the best that each and every stone had to offer. All of these characteristics give old cut stones a unique look and a different sparkle factor!”

During the Art Deco period, the Old European cut became a new method of cutting that was more precise and defined. A true roundness was achieved with Old European cuts, and these became the predecessor for the modern round brilliant cuts seen today.

“Old European cuts are the most popular cuts of antique diamonds in our store. Although, they may share the same number of facets with their modern brilliant offspring, the shape and placement of each facet gives each cut its uniqueness. Antique stones capture light differently. They draw your eye into the stone. The facets are much larger and are placed to create ‘FIRE’ and they also reflect more light out to the viewer's’ eye in broader angles.”

The father of the modern round brilliant diamond cut, Marcel Tolkowsky, invented a mathematical formula that aimed to achieve the most desirable brilliance in a diamond. In 1919, he published specifications stating that a diamond has to be cut in 58 facets in order to maximize reflected light or its brilliance. This specification later became known as the American Standard and used as a guideline for gemologists and diamond cutters.

Today, antique diamonds are still very much sought after because of their uniqueness and charm. They are also becoming rarer because of their age, which also adds to their popularity. Many people are in the market today for antique diamond engagement rings. Croghan’s was featured in an online article on Martha Stewart Weddings about finding the perfect antique diamond engagement ring. And that is why we are in LOVE with antique diamonds! Come and play in our Jewel Box with Ari and Corina of Single Stone next weekend! They will WOW you with their amazing selection of antique diamonds set in the most beautiful new handmade mountings.
