The History of Jonathan’s Fine Jewelers

Since 1991 Jonathan’s Fine Jewelers has been quietly collecting, designing and providing the finest quality custom jewelry and diamonds to Houston and the surrounding areas. Built on word of mouth and reputation, Jonathan’s has access to the largest inventory of loose diamonds in the country and is the go-to jeweler for all custom designed pieces of jewelry.

Hanging a shingle on a door, Jonathan Siegel found an untapped niche in the Houston jewelry market by buying estate pieces of jewelry and diamonds from individuals and then selling those pieces to his contacts all over the country.   Although Jonathan is no stranger to the jewelry business and is a third generation jeweler, he knew the key was to provide a service that no one else offered.

Jonathan eventually met Sergio Nuncio, a young man who had as much drive and determination as Jonathan, and a partnership was born. Jonathan’s Fine Jewelers was relocated to a new space that was shared with a jewelry designer, who introduced Sergio and Jonathan to the world of custom designed jewelry. Read More Here
