Lost silver ring with a blue stone and delicate filigree, lost near a rock outcropping in the Wyoming mountains.

I lost a beautiful silver ring that belonged to my grandmother while hiking in the Wyoming mountains last weekend. It has a lovely blue stone in the center, surrounded by delicate filigree work. I realized it was missing after taking a break near a rock outcropping. If anyone finds it, I would be incredibly grateful to have it back, as it holds so much sentimental value for me.
