Lost family ring (long shot)

I know this is the longest of long shots, but I have to try. A year ago I visited Houston to go to a concert. When we were there, we stayed at the Hyatt House Woodlands hotel for two nights. At some point on this trip, I lost my travel jewelry box. It is black, leather, and can fit in your hand. It rolls up. I called the hotel and they checked with lost and found and the cleaning staff, with no luck. It would not be that big of a deal if it didn't have Mt dead grandmother's diamond ring in it. The ring was silver with two diamonds of different shapes. The diamonds were taken from my grandmother's wedding g set and made into a ring for me. Like I said, I know it is next to impossible that its still out there, but I am out of ideas and heartbroken about it. If you know of ANYTHING related to this ring or jewelry box, please let me know.
