Slight Uplifting
Just my guess it's the plastic rings that they used when they were kids, they had pretend to play house, husband and wife. Instead of the couple rings he had brought with the necklace, he was going to get them copied in precious metals and gem stones. To give to her for her birthday. The next day when she walked in to the office the necklace that hung on the headboard was gone. The photo had been changed as well.
