The price of a Persian rug can vary widely, but some pieces are considered exceptionally valuable due to factors like age, knot density, materials, and craftsmanship. Expensive Persian rugs are often antique, hand-knotted masterpieces made from the finest wool or silk. The rarity and historical significance of these rugs add to their value, as does the reputation of the region or master weaver. These rugs are not just floor coverings but investment pieces, treasured by collectors and enthusiasts alike.
