It looks like they (Frederick Goldman Inc.), are a huge jewelry manufacturer based in NYC and have been around for years. I can't find a website on them. Got this off Cornells Jewelers site:
The Goldman family tradition or excellence spans a period of over fifty years. Frederick Goldman founded his company in the late 1940's as a one-man operation specializing in plain wedding rings. The Goldman line was expanded to include engraved wedding rings in the 1950's. Today, Frederick Goldman, Inc. is headed by Jonathan Goldman, as chairman and CEO and his brother Richard as President. The small company founded by their father has grown to become one of the largest jewelry manufacturing companies in North America offering its customers a large selection of jewelry products across its many separate divisions. In addition to being an extremely large user of gold and diamonds, Frederick Goldman, Inc. is the largest user of platinum in the United States for jewelry purposes.
