Italian victorian floral ornate standing picture frame. 3X3 photo glass? Resin?

Italian or victorian floral ornate standing picture frame. 3X3 inch photo Frame is either glass or resin but it’s a heavier frame so I’m thinking it’s real glass. See photos for perimeter measurements. Beautiful piece! This is a pre-owned vintage item that may show minor signs of normal wear. Please review photos. Absolutely stunning piece!
