Thespia....I used to think "estate" as pertaining to jewelry to mean that a piece was old. But found out it can mean newish too. It can mean that say...I passed away and my daughter decided to sell to my jeweler or trade with him on some pieces I had. Then, the jeweler takes my pieces and offers them for sale as "estate." or...my estate, meaning what I leave behind, is sold at auction by my heirs through their/my lawyer. Someone, could be a jeweler, or anyone, buys some of these pieces and turns around to sell them to hopefully, make a profit. These are now "estate pieces" and can be old or they can be new. I'm sure other people can give you more definitions, too.
It may not be bad karma at all. Someone may have just wanted a larger diamond or was getting rid of that regular "maul" diamond that did not shine for a super ideal cut,hearts and arrows diamond that looked like it was on fire.
