Jewelry
" A) Ring on the fourth finger of the left hand, yellow metal band, and the inside is inscribed with "14 K" and the letters "TW" within a circle."
Perhaps the letters TW within a circle correlates to this company, as their Hallmark-Maker's Mark, as it shows a diagram of TW within a circle:

"On Tuesday, April 11, 1950, a U.S. federal trademark registration was filed for TW by TESSLER & WEISS, INC., UNION, NJ 07083. "

I put in a zipcode for Tulsa, Ok. and within 50 miles there are stores that are authorized dealers
for Camelot Bridal Retailers.
Now whether these stores were in existence in 1995 or previous to 1995, I haven't checked them out, so I don't know...
There are several stores listed, and I listed these 2 as they aren't too, too far away from where the couple was found...
There is a store in Henryetta and in Muskogee. Just a guess incase this couple was
from around this area...

ETA:
The store in Henryetta has been in business since 1953.
I don't know about the other store...
Speculating... just throwing out ideas...
