This is a beautiful example of La Roco Jewelry. This Brooch is a gold tone braided open work with Jewel tone rhinestones in shades blue and green. The luscious green are set with the dark blue rhinestones, using cabochons, marquise and pear-shaped rhinestones to make this a knockout brooch. T
Measures : 2 3/4" in diameter

If you are not familiar with La Roco, here is some Company Information from Kaleidoscope Effect Jewelry website: "Based in Seattle, Washington, American jewelry company Layko, Ross & Co Inc. began its activity more than hundred years ago, in 1918. According to sources and jewelry pieces available on the vintage jewelry market, the company ceased operations in the 1960s. Traditionally, the designers used high quality materials for creating beautiful lockets, earrings, tie clasps and brooches, which have perfectly survived to this day. Jewelry from this manufacturer is quite rare, sold at auctions.

Basically, La Roco products were not marked, but sold with a tag. Occasionally found on clips, the “La Roco” hallmark in script is for some reason almost never used on brooches."

It is not unusual to find La Roco unsigned...see examples on p.193 of Julia Carroll's book "Collecting Costume Jewelry 101"
