Unusual vintage cross pendant in gleaming solid gold

Just under an inch long and 5/8" across, this piece is somehow both delicate and substantial, with a very wide bail allowing for use with most sizes of chain or cord. It weighs 1.9g. There are no hallmarks but it has been tested as 13K solid gold, and I will furnish the jeweller's certificate attesting to this. In very nice shape, with only tiny surface scratches and very bright colour, with a bit of a duller patch on the lower part of the backside (see last picture). Cross listed in Women's and Men's markets. (h)
