What Is An Old Mine Diamond?

We've all heard the saying, "Old is Gold." At Marci Jewelry, we believe that statement to be even more true when it comes to diamonds. Since our establishment in 1971, we have come to appreciate the charm of 'Old Mine Diamonds'. These gems, dating back centuries, hold a special place in our hearts, just like the family stories that have been passed down in our own business. So, let's embark on a fascinating journey to understand these exceptional diamonds.

Characteristics of Old Mine Diamonds

Old mine diamonds, known for their cushion-shaped cut, are quite distinct from modern diamonds. Here's what sets them apart:

  • Understanding the Cut: Unlike modern round cuts, old mine diamonds have a more square or rectangular shape with gently rounded corners. This cut reflects light in a distinct, captivating way.
  • Color and Clarity: While they can be found in various color and clarity grades, old mine diamonds typically exhibit a warmer color and contain unique inclusions.
  • Carat Sizes: They are often found in a wide range of carat sizes, some being quite large due to less cutting technology constraints in the past.

History and Origin of Old Mine Diamonds

The journey of old mine diamonds is as intriguing as the diamonds themselves. Originally discovered in the 18th century, these diamonds have seen the evolution of the industry we passionately serve today. They were initially mined in India and Brazil, before the discovery of diamond mines in South Africa in the late 19th century.

The Value and Rarity of Old Mine Diamonds

Old mine diamonds are often considered more valuable than their modern counterparts due to their historical significance and their scarcity. They represent a time before machinery and modern cutting techniques, making each diamond a unique piece of history. We at Marci Jewelry understand the charm and allure of these gems and provide a selection suitable for a range of budgets.
