A thrift shop find last Thursday > 585/14K white gold and four diamonds. Bought in a group lot of other jewelry I saw in one of the cases. My Unsolved Mystery is the meaning of the numbers on the inside of the band. A registration number? Something else? Age? I would think mid-century but don't really know for certain. The Oak Leaf is the Assay gold mark for Waarborg, The Netherlands. That particular oak leaf mark has been used since 1953. The shop I bought this from prides themselves on weeding out the gold from the rest....well, not that day....LMAO!!! TIA for any info.

Wow, a great find Bonnie. You have to know as much as you I guess to know what you find!
Hey val - yes, this one is a keeper because the design is out of the ordinary.
@racer - LOLOL!!! I was really surprised that they missed the marks. I picked it out because of the construction but had no intention of examining it in front of Andrea, the shop owner. I just put it with the rest of my stuff and examined it after I got in my car (well out of her view, hahaha!).
I always say you can't catch everything. Great find!
585 represents gold fineness. It denotes that 585 parts out of 1000 parts of the item is gold. The rest is other metals. 585 represents 14 karat gold. The higher the gold karat, the softer the gold. An engraving of 585 or 583 implies that the gold ring is of 14-karats and has 58.3% of gold in it while 41.7% is other metals. The 9107 is probably the makers mark.
@lugnuts - thanks much, but I know all about numerical gold marks and what they mean in regard to metal purity. Waarborg is the Dutch Assay Office. I might just have to email Waarborg to see if there is a record of that number, if it indeed traces back to the maker.
