Where to Buy Vintage Style Diamonds: Old Mine Cushion Diamonds That Sparkle

In decades past, jewelers would take vintage diamonds and re-cut them into more modern cuts. This is akin to committing diamond sacrilege. Re-cutting these beautiful stones into modern cuts may have “updated” the cuts, but reshaping a diamond will invariably reduce its weight. What’s worse, though, is the loss of a vintage styled diamond that given enough time will come back into vogue. The short-sightedness employed in such a practice while deplorable, is a product of the pressures of commerce. It is difficult for a merchant to hold on to stock without any type of guarantee that those styles will become fashionable again at some point in the future. Styles do cycle around and often what seems dated in one decade given 20 to 30 years becomes “vintage” and interest is revived. Today, jewelers and trades people have again come to appreciate the beauty of the antique faceting seen in these timeless diamonds. There has been a strong uptick in demand from consumers for these vintage styles. Antique style diamonds do have a special charm. It’s no surprise that the interest in vintage jewelry has increased dramatically of late.

The above diamond has an Ideal or 0 Cut grade which is the highest cut grade issued by AGS. An AGS Ideal Cut diamond is considered by many to be one of finest cut diamonds in the world. An Ideal cut grade is reached by factoring in polish, symmetry, proportions and performance scores of a diamond.

The Canera Antique Cushion is a high performance cushion cut diamond. The old mine cut diamonds of the 19th and early 20th century did not have the benefit of the advancements in light performance that we have today and therefore did not display the optimum traits that the new designs exhibit. The Canera Antique Cushion is designed by Victor Canera and combines both the charm of the old style cuts while incorporating advancements in the science of light performance. Within its beautiful “pillowy” outline, the Canera Antique Cushion employs an antique facet pattern inspired by Old Mine Brilliant diamonds of centuries past. This type of faceting is commonly referred to as being “broad faceted” or “chunky faceted”. These terms accurately describe the large, optimally tuned facets employed in the Canera Antique Cushion that reflect broad flashes of light compared to modern diamonds that have a more “splintery” reflective character.

History of The Old Mine Cut

Most Old Mine Brilliants existing today are diamonds that have been handed down from generation to generation. These antique diamonds while charming are often lacking in many areas. First of all being used diamonds, these antique stones can have many signs of wear, including chips, abrasions, and cracks. These stones, having been cut at a time when diamond cutting technology was not as developed as it is today, are also severely lacking in cut precision. It’s common to see antique Old Mine Brilliants that are lop sided and the poor craftsmanship is easy to spot. In addition to physical symmetry polishers had little to no understanding of light interaction in a diamond or the notion of light performance.

The Gemological Institute of America informs us that centuries ago, diamond cutting was a slow process. The less material the cutter removed from the original rough diamond crystal, the more quickly he completed his work. If a diamond cutter took too long to complete a task they would see their wages cut as a penalty. Therefore, the typical cut during this time was actually a squarish, sometimes slightly oval cushion-brilliant. The name used by most jewelers today when refer to such shapes is the “old mine cut.” This cut’s defining characteristics are more often than not a squarish shape. The old mine cut diamond’s top and bottom -ie crown and pavilion- were both much deeper than are in the cuts employed in the shaping of today’s diamonds. In the mid-1800’s  Coster’s Amsterdam diamond cutting house was largest diamond cutting establishment in the world. It employed a labor-intensive process that included three phases of operation, each phase required specialized skilled labor to split or cleave the diamonds, cut the diamonds, and finally polishing the diamonds.

In the 1870’s a “bruting” machine started being employed which gave the diamond a round outline. The first angle gauges led cutters to use the angles associated with today’s modern cuts. In the year 1900 a second event changed the way diamonds were shaped: the circular saw came into use. This new tool made it a great deal easier to split the typical octahedral-shaped diamond rough crystal into two pieces. This in turn made it possible to cut the smaller top piece into a finished diamond. The technique which had been employed prior to this was to simply grind it away. – A waste of precious diamond which would no longer be necessary. Within the next couple of years many in the industry realized that using the saw saved weight from the common octahedral diamond crystals, which meant that the new proportions could be cut without the type of waste of diamond rough that previous techniques had caused. This change shifted the emphasis from weight recovery to allowing diamonds to be cut into prettier shapes resulting in the many designs which eventually have become the styles that we see today.

The cushion diamond had a big increase in popularity during the 19th century. Old mine cuts are often confused with modern cushion cut diamonds. Today, some cushion cut diamonds are actually certified as “old mine brilliants”. Old mine cut diamonds are somewhat similar to cushion cuts the main difference being that old mine cut diamonds have fewer facets and the proportions also vary.

The cushion cut is a modern take on an old style, as it has more of the sparkle expected in diamonds, while still having a shape reminiscent of the old mine cuts.

Cushion cuts have been in high demand in the past few years, yet it was not until the Canera Antique Cushion came on the scene that anyone had been able to bring out the true chunky faceted style of the Old Mine Cuts and still have the diamond display the optimum light performance that makes a diamond sparkle. In the end this sparkle, fire and brilliance is what diamonds are famous for.
