Hi Pat, thank you for writing in. Whiteside & Blank - Newark, NJ: 1899 - 1917; manuafactured gold, platinum and plique-a-jour jewelry. They used an arrow trademark as you described.
Plique a jour (French) is a technique of decoration in ENAMELLING by which the design is outlined in metal and filled in varioulsy colored transparent enamels but with no backing behind the enamel, so that the effect is similar to stained glass windows.
The work in jewelry was usually executed in a gold setting. The method was discovered in the 15th century by Benvenuto Cellini during the Renaissance and was reintroduced in c. 1900's.
How wonderful to see the original antique gold chain on this antique gold jewelry. Thanks for writing in...
