Lost Antique Diamond Pendant w/ Interlocking Circles (Denver)

Hello all. I recently lost a diamond pendant attached to a gold chain necklace that is very dear to me and impossible to replace. I slipped it into a sweater pocket on the way to dinner, and then took that sweater to my dry cleaner a day later. It's possible that it could have fallen out at dinner in cherry creek, but it could also have gone to my dry cleaner and the employees there did not return it. I have no way of knowing. If by some chance you come across my necklace, I would be willing to offer a cash reward for its return, no questions asked. Thank you for reading my post.
