French Retro Crossover Ring
Sleek, streamlined, and thoroughly Modern. A French crossover ring lavishly set with diamonds and crafted in the post-Deco, retro style. The iconic dog's head assay stamp confirms construction in solid platinum, and the diamonds are a mix of baguettes, round brilliants, and an old Euro at the centre. The stones are dazzling, icy white, and perfectly complemented by the cool platinum tones. It was made towards the latter half of the 1930s and remains in excellent condition nearly 100 years on.

Condition
We offer detailed and accurate condition reports on each listing. These pieces are antique, vintage, or pre-loved and often over 100 years old so they're going to have lived a life. A healthy patina and the odd scuff or scrape is quite normal... it's part of their charm! Everything we present has been checked over by our jeweller and should be good for wear for many years to come (unless otherwise stated) but please remember to treat them with appropriate care and consideration for their age.
