VERY GOOD: This French Art Deco rose cut Diamond engagement ring is in fabulous condition throughout. The charming rose cut Diamond is something that is fairly unusual to find in modern jewellery, giving Diamonds a completely new tone and dimension altogether. Albeit a shallow Diamond, pointing to its creation in the 1930s rather than the 1920s, it has plenty of vivacious character! The shape of the ring has evidence of some resizing the past. Overall, a stunning vintage Diamond engagement ring!
