Unworn ring with antique 0.887 ct old European cut solitaire, around 1900/2020

As antique jewellery dealers, we sometimes receive unmounted antique diamonds from the stocks of dissolved goldsmiths or from pieces of jewellery that could no longer be repaired. We are then happy to remember the tradition, cultivated in earlier centuries, of giving beautiful gemstones a second life in a contemporary piece of jewellery. Such a unique gemstone is presented here. This large old European cut diamond from around 1900 has a beautiful presence. Its weight is 0.887 ct, it is warm toned (K) with very good light refraction as well as small enclosures that make its appearance distinctive. You can see this irregularity in the crystal lattice of the diamond with a magnifying glass and thus recognize the diamond among all others. In order to present it according to its antique cut and yet in a timeless way, we have chosen a setting from a manufactory in Chicago that still produces settings in the style of American Art Deco. Luminous white gold was already characteristic of American jewellery in the 1920s, and to this day it has lost none of its topicality and cool elegance. Amidst delicate floral piercings that resemble lace, the large brilliant cut diamond is presented slightly raised above the finger. The cool toned precious metal contrasts beautifully with the warm glow of the antique diamond. Thus a perfect engagement ring has been created for all those who want to write the story of their engagement ring from scratch themselves - and yet appreciate the elegance of antique jewellery and the individuality of old brilliant cuts.

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 century 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 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 European cut", the proportions of the stone do not follow the standard of today's brilliant. Old European 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.
