Charles Oliver Bruff
- Employed an English jeweler skilled in diamond and enamelwork. They produced enameled lockets and hair plaited lockets.
- Began to do lapidary work. This practice was frowned upon by Great Britain as they wanted the colonies to import products from them, not produce any of their own. This was the beginning of a national interest in manufacturing in the colonies.
- Their lapidary produced seals with heraldic, arms, crests, figures, etc. to sell to customers as well as to other jewelers.
- During the Revolution they made swords and other military items.
