Antique Art Deco 1.59 carat Transitional Cut diamond filigree engagement ring

A twinkling 1.59 carat GIA certified antique cut diamond solitaire in its original Art Deco mounting. GIA graded this jazz-age diamond as a Circular Brilliant, a designation that describes diamonds with features of both Old European and Transitional cutting techniques. In our opinion, this diamond leans heavily towards the "Old Euro" team, with a wee table, a large culet and an indulgent, kaleidoscopic sparkle. Its face-up size is a total delight: nearly 8mm of sparkly spread. The diamond fills the octagonal head right to the brim, tucked into place with eight discreet prongs. The 18K white gold mounting is rich in detail, with floral, bow and lattice motifs across filigree. Milgrain and decorative edging throughout. 

This ring comes with a jewelry appraisal for insurance/replacement as well as a GIA Diamond Report. View the report here.
