Signed DURI Art Nouveau Earrings

Well during my recent thrift store visit, I picked up several pairs of earrings, this pair caught my eye with its Art Nouveau design, and the inlaid abalone shell.
Well, they are signed DURI (c) and it seems that the company is not well known, except that they produced for two decades – in 1960-1980s (see below info). The earrings are like new, and measure from post to the tip 2-1/4" x 1-1/4". Nice find for $1.99.
