1.19 Old European Cut Diamond Engagement Ring in Platinum.  This vintage inspired modern engagement ring features 1.30 carats of diamonds and .30 carats of emeralds finished in platinum. The center stone is a 1.19 carat diamond with a very light golden hue. Set with surface prongs in a structured, milgrain mounting, the center stone is flanked by four (4) .075 carat emeralds. The emeralds have a lush forest green hue. Sixteen (16) .0068 carat accent diamonds decorate the shoulders of the tapered band. From the profile, an elongated openwork mounting gives this engagement ring a neo-futuristic look.
