Toronto-based Aber Corporation, a diamond mining and exploration company, purchased a 51% controlling interest in legendary luxury jeweler Harry Winston Inc.

The acquisition helps Aber to become more vertically integrated by giving it a retail outlet for its diamonds. Harry Winston, which has built a reputation as “the jeweler to the stars”, had remained in family ownership for much of its 75-year history.

Dyens & Co. was the sole advisor to Fenway Partners Inc., a NY-based private investment firm that had purchased a 55% interest in Harry Winston in December 2000, and Mr. Ronald Winston.
