I decided to play the silver strike look-alike machine at the Atlantis in Reno that dispenses jewelry. Much looser than the multiline strike machines there. Won a small garnet and diamond necklace. Redeemable for $100. Neither my wife nor I are sure how nice these things are since they are hard to see against the black background in the capsule. Even the ones on the machine display were hard to fully appreciate. Once you open it, you can't redeem it.

Are these items any good, or are we better off just redeeming it?
