A clean slate

Antique half carat in a modern platinum ring, circa 1910/2020

For those who enjoy the individuality and craftsmanship of old pieces of jewellery and yet hope to celebrate an engagement or other event with a piece of jewellery whose history can be rewritten from scratch - this ring is for them. For a half-carat diamond cut in the years around 1910 in its original setting, we have had a matching ring rail forged in our workshop, which now makes the diamond wearable as a timeless solitaire ring. The diamond is in the so-called old cut, the predecessor of our modern brilliant cut and weighs about 0.52 ct. Its brilliance is less cool and glaring, but somewhat softer than that of modern brilliants, although the cut is geared towards brilliance and fire, and both qualities are wonderfully displayed in the featured gemstone. The individually cut centre stone is accompanied by two further baguette-cut diamonds, which lead on to the plain ring band in platinum. Platinum, this incomparably white precious metal, whose hardness allows for special subtleties in processing, was already perceived as the ideal complement to diamonds in the early 20th century. Thus, in choosing the metal for the ring band, we were guided by the original diamond setting with delicate mille handles. The resulting ring is unworn, even though it contains historical elements - and is thus ready to become the bearer of entirely new and personal memories without sacrificing the individuality of an antique stone.

The shape of the diamond has evolved over many centuries. For a long time it was technically impossible to change the raw crystal more than rudimentary, because the diamond is so extraordinarily hard. In the 17th and 18th centuries it was then possible to extract more and more facets from the crystal, and in the course of the 19th century the cuts came closer and closer to the shape that we know today as a brilliant. It was not until 1919, however, that Marcel Tolkowsky calculated the ideal shape of the brilliant on an optical-physical basis; the exact shape, which is the standard in Germany today, the so-called fine cut of the practice, was not even determined until 1938. The shape of the modern brilliant-cut diamond really became established after the war. The brilliant is therefore actually a fairly recent invention - and this also means that with a diamond cut in the 19th century or at the beginning of the 20th century, a so-called "old cut", the proportions of the stone do not follow the standard of today's brilliant. Old cuts were always cut individually in those days: One wanted to find the optimal way between the best brilliance on the one hand and the least loss of material during cutting on the other. We find that it is precisely this individuality that makes old diamonds so particularly interesting. They are less easy to compare, and their value cannot simply be determined by means of a table: Because you have to look at each stone individually to really be able to say whether it has the fire and brilliance that you expect from a diamond.
