Art Deco Asscher Cut Diamond Engagement Ring in Platinum.  This stunning Art Deco engagement ring features a 1.54 carat Asscher cut diamond with sapphire and diamond accents in a platinum setting. Asscher cuts are a fantastic old cut with a very distinguishable symmetry. This ring has a lovely design with open work in the smooth contours, and has neat lines of single cut diamonds up the shoulders. A beautiful color contrast between the sapphire and diamond adds that final piece to this rare vintage piece of art.
