Thank you for contacting Mearto with your appraisal inquiry, and I apologize for the delay. This brooch is made from a semi-precious metal wire construction, with stone settings soldered together in the interior of the design. The soldering is well executed, and there are not any flaws in the construction of the piece. The stones are foil-backed, and set properly and soundly. The piece is in good condition, and shows no signs of wear or damage. Given the condition of this piece, and completed auctions of similar items, a fair market estimation is 60-70 dollars. Please reach out with any questions. Bo Stuck
