Certificate of Ownership for.....

Ah, Lindenwold Fine Jewelers! I remember getting junk mail from them regularly about 10 years ago, always to let me know that I won a fabulous prize of a genuine Cubic Zirconia, sometimes two of them, absolutely free. And by the way, wouldn't I like to buy a nice setting to have that great prize mounted in? I was required to return some Official Eligibility Affidavit Certification (or something like that) in order to receive the prize. I never bit on the mounting, but over the course of a year or so I bet I got over a dozen free CZ's from them. They always delivered them.

From the text at the bottom of that certificate it seems like the same gimmick - get something free, but entice you to buy something to keep it in. Too bad they never offered me coins!
