Ari Kastan is currently on Etsy as Kisufim Jewelry; he used to have his own website under his own name.
His work takes its inspiration from vintage and antique pieces. Currently, he is showing a lot of padlocks, which were a popular Victorian motif on bracelets in particular (acting as the lock).
Here, he uses 14k rose gold and rose cut cognac diamonds to fill in the face of the padlock. There is no chain included.
This sells for USD$1,356.52.
