A beautiful and timeless Art Deco platinum diamond trilogy ring set with two round brilliant cut diamonds and one central Old Mine cut stone with a total weight of 0.50ct approx. With lovely bright diamonds that scintillate very well this antique, pre-loved ring would make a super engagement ring. Designed as an 'Up/Down' ring with the diamonds set on the vertical rather than across the finger. This is a very flattering style to elongate the fingers.
