15ct Old Mine Cut Diamond Star Brooch with Black Enamel

The Curio



I am in love with this diamond star! It’s such a beautiful and versatile piece that may date back to the 1860’s. Featuring a large and juicy old mine cut diamond, this piece was likely originally part of a tiara, as the back fitting would allow for attachment as such an ornament if desired. The amazing thing about the brooch is the shape: you have the geometric shape that leads the observer to believe it is from the 1860’s and you do see a lot of the “block” geometry in fashion, jewelry, and all decorative arts of this period. There was this desire for geometry that we just don’t see in any other moments of the 19th century.
