All my heart is yours

Precious diamond brooch in gold & silver, around 1900

Pieces of jewellery are objects that can be as personal as hardly anything else. Every wearer must be able to identify with them, and it is not uncommon for jewels to emanate a special power that makes one think they are charged with pure emotion, as if they were a repository for feeling. This often expressed thought is not coincidental, since jewels are often testimonies of human feelings, sometimes they are also visible symbols of shared happiness, precious memories or love. We have such an object before us here - and there can be no doubt about its content: It is a heart made of diamonds. There are 44 stones in the historical old cut of together about 1.10 carats embedded in the face of the heart. They are set in silver which, with its light patination and warm colour, provides a beautiful foil for the white sparkle of the gemstones. The brooch is made of high-carat gold on which the silver is superimposed. This time-typical technique, called "silver on gold" in English-speaking countries, prevents the piece from rubbing off on clothing when worn, which pure silver jewelry occasionally does. The diamond heart is beautifully preserved and an emotional gift to a loved one - today as it was over a hundred years ago!

In ancient times, diamonds were valued primarily for their incomparable hardness. As symbols of invincible strength, their beauty was secondary at best. In fact, early diamonds do not appear at all attractive to the modern eye. Medieval cutting techniques also did not allow for spectacular light reflections, and the widespread table cuts only brought out the brightness and color of the stones. All this changed in the course of the 17th century. The nobility of the Baroque period developed a taste for glittering gemstones. Rose-cut diamonds, whose many facets reflected candlelight beautifully, were particularly popular. In the middle of the century, a first, early brilliant cut developed, called the Mazarin cut after the influential Cardinal Jules Mazarin, characterized by a crown of 17 facets. By the end of the century, these diamonds were then replaced by a new shape, named the Peruzzi cut after its inventor. Vincenzo Peruzzi was a gem cutter from Venice, who increased the crown of the diamonds by additional facets to a total of 33, thus increasing the fire of the stones enormously. However, these early brilliant diamonds were not standardized in terms of the number and shape of the facets. Each stone was cut in such a way that as much substance as possible could be preserved. New diamond deposits in Brazil in the second half of the 18th century then led to a cut shape that became known as the Old Mine Cut. These diamonds are already very similar to today's full-cut diamonds, but it would take several more generations of continuous development of the cutting technique before the Old Mine Cut became the Old European Cut, and finally, in the 1940s, the modern full cut.
