Name of pearl company, etc.

Hello: My husband gave me a beautiful cultured pearl necklace which I wore for our wedding. It came in a heart shaped box and I think the name Cordora or Cadora was on the box. Is this the name of a company that produced the necklace?

Unfortunately, we had a robbery and the pearls were stolen. I am heartbroken and wondered if company still existed. They were 40 years old. Anybody ever hear of this company, probably out of New York City area. Thank you.
