This uniquely fabulous vintage diamond ring explodes in a blaze of bright white diamonds centering on a faceted triangle, or trilliant, cut diamond weighing 2.09 carats. The artfully sculpted, multi-dimensional mounting, rendered in platinum, combines baguette and round diamonds for a brilliant effect. We estimate the vintage of this platinum ring to be from the 1930s through the 1950s due to the trilliant cut diamond, and may be one of the earliest examples of jewelry to utilize this modern cut. In any case, this is a truly remarkable, impressive and unforgettable vintage diamond ring.

Center Diamond details
Cut/Shape: Modified Triangular Brilliant Cut* *Lang determines cut/shape based on visual appearance and knowledge of antique cuts. The GIA laboratory uses mathematical parameters to determine the cut/shape for their reports which can result in differences between Lang and GIA cut/shapes designations.
Carat Weight: 2.09 carat Because mountings prohibit full and accurate observation of gem quality and weight, all data pertaining to mounted gems can be considered as approximate unless accompanied by an independent laboratory certificate (AGL, EGL, GIA). Unless otherwise stated, all colored stones and pearls are assumed to be subject to a relatively stable and possibly undetected color and/or clarity enhancement.
