Elegant bone china - four small pieces

These are small, delicate, elegant, and beautiful, with a similar flower theme. Auction is for all four together. Condition is pretty much perfect, I have no idea of age. The two “Paragon” pieces (with scalloped edges) seem identical. The “Queen Anne” dish says “duet” and I guess this refers to the two roses. The small covered bowl has no markings, perhaps not bone china, but made in same spirit as the others. Would prefer pick-up (as they are delicate) - Royal Oak area. Shipping might be an option, I guess around $10, and definitely at buyers risk.
