Vintage Polished Soapstone Hand-Carved Floral Inlayed Jewelry/ Trinket Box 4"X 1." The floral design on the lid uses an inlay technique called Pietra Dura where polished stones and Mother of Pearl (MOP) are cut and fitted to create images. This technique is associated with traditional craftmanship from Agra, India. The cylindrical hollowed out base is made from the same soapstone with unique earthy veining.
