Art Déco Engagement Ring with 4.30 ct Transitional Cut Diamond, c. 1930

Art Déco Engagement Ring with 4.30 ct Transitional Cut Diamond, c. 1930

A large, high-quality diamond weighing around 4.30 carats is the centerpiece of this finely crafted ring. The large diamond is shaped in the so-called "transitional cut", the early form of the brilliant cut, which marks the transition from the old cut to the modern full cut. It is warmly tinted, which is a beautiful basic tone under the colorful fire of the stone. The diamond is also very pure. Very small inclusions (VS1) can only be seen in the stone under a magnifying glass. The diamond sparkles in an airy prong setting made of high-carat white gold, which is held in place by a platinum ring band. Seen from above, nothing distracts from the magnificent diamond. It stands completely on its own and determines the effect of the piece of jewellery alone. Seen from the side, the setting surprises with small lily flowers set between the prongs. The cut of the diamond and the design of the elegant setting allow us to date the ring to around 1930. It came to us from Switzerland, where it was possibly created. The ring is accompanied by detailed appraisals from Vienna.
