Delicate silver ring featuring a tourmaline

Ring bought at Pierres d’ailleurs boutique on Saint-Denis Street in Montréal, June 2025. It was sold as a sterling silver ring with genuine tourmaline, but there is no hallmark on the band, so I can’t guarantee anything, but this boutique is well known for selling genuine stones and jewelry pieces. I don’t know what the small clear stones beside the tourmaline are. I usually wear sizes 4,75 and 5, but this ring feels slightly bigger (see measurements on picture). No wear, no tarnishing, but expect some irregularities due to artisan making. Smoke free home.
