Six pieces of jewelry from the collection of notorious Ponzi schemer Bernard Madoff and his wife Ruth are going up for auction today, the U.S. Marshals Service said, more than seven years after Madoff’s $64 billion scam was uncovered.

The pieces, available at an online auction hosted from Texas, include a bracelet studded with more than 650 diamonds starting at over $21,000, an emerald necklace starting at $15,300, a leaf brooch with nearly 100 diamonds starting at $11,050, two sleek, gold watches each starting at more than $21,000 and a gold money clip in the shape of a paperclip starting at $380, according to the auction website.

Though Madoff was arrested more than seven years ago, officials are still attempting to track down the money he stole in his decades-long Ponzi scheme — including recouping some losses from major auctions. Previously, Madoff’s houses and yachts were sold or auctioned off for tens of millions.

Established in 2006, the eVolo Skyscraper Competition has become the world’s most prestigious award for high-rise architecture. The contest recognizes outstanding ideas that redefine skyscraper design through the implementation of new technologies, materials, programs, aesthetics, and spatial organizations.

Studies on globalization, flexibility, adaptability, and the digital revolution are some of the multi-layered elements of the competition. It is an investigation on the public and private space and the role of the individual and the collective in the creation of dynamic and adaptive vertical communities.
