This modern style Christmas tree pin is designer singed JJ for Jonet Jewelry and was made in the mid to late 1960s or early 1970s. 
 
The tree is segmented at cross angles and is made of silver rhodium metal. All of the segments are paved with faceted silver aurum chatons that look like Marcasites, but they are bright silver, not dark grey. In the photos, the brooch has what looks like gold in the background but it is just a light reflection. 
 
The tree is medium large in size at 2" tall x 1 3/4" wide or 5 cm x 4.4 cm. The entire brooch is in pristine like new microscopically clean condition with no imperfections or signs of wear. All of the silver aurum stones are original and present. The back has the original fine working safety clasp and the JJ signature. 
 
Comes gift wrapped and shipped in a new presentation jewelry box.
