Thank you for contacting Mearto with your appraisal inquiry, and I apologize for the delay. This brooch is in good shape, and appears to be made of semi-precious metal. Based on the styling and construction, it is from the mid 20th Century. The stone settings are solid, and there appears to be no damage or significant wear. Given the condition of this piece, and completed auctions of similar items, a fair market estimation is 40-50 dollars. Please reach out with any questions.
