Merle S. Koblenz, a third generation jeweler, grew up in her family’s jewelry business in Albany, NY, and has been buying and selling antique and estate jewelry since 1980 in her own business. 

Our collection includes timeless pieces with exceptional beauty. My antique and estate jewelry pieces are perfect for collectors as well as for the discriminating buyer.

In order for jewelry to be called antique it should be at least 100 years old and, more recently, pre-owned jewelry is generally called estate.

Often antique and estate jewelry is made better and priced lower than new jewelry. In addition, like fine art, many items gain a special quality over the years from being cherished by its owners and admired by others.
