Craftsmanship & Ethics

Heirloom Quality

Laura Preshong Ethical Fine Jewelry is designed and fabricated in the South End of Boston Massachusetts, using engineering, technology and old world jewelry making techniques. We hand create an exclusive 'small batch' heirloom quality jewelry not available in mass produced, high volume jewelry manufacturing. Our Design process involves skilled jewelry designers using advanced computer aided design software (CAD) to assist in the research and development of our ethical jewelry pieces. The designs are printed in wax, then cast one at a time into the precious metal of your choice. The jewelry pieces are hand filed, sanded and soldered to ready for stone setting. The Ethical Diamonds and Fair Trade Gemstones are set by hand using traditional hand setting tools and classic setting techniques. The fine jewelry pieces are then sanded and polished to a satin or high polish finish. All Laura Preshong Ethical Fine Jewelry is guaranteed to be made of the highest quality materials and jewelry fabrication,
designed to last a lifetime.
