In case you haven't heard, . Her boyfriend proposed on July 17, and he gave her an art deco-style diamond ring, pictured above. The ring's center stone is an Asscher cut diamond that is said to be about three carats in size, and it is surrounded with an octogonal halo of smaller diamonds.
Asscher cut stones have had a resurgence in popularity recently, but they are still far less common than round, cushion and emerald cut diamonds.

The most famous Asscher cut diamond is the Krupp Diamond, which Richard Burton bought for Elizabeth Taylor in 1968. The actress wore it as a ring, and the 33.19-carat stone was sold by Taylor's estate in 2011 for $8.8 million.
