Round Blue's & Teal WEISS Dome Brooch

here is another brooch from my (growing) collection.

WEISS signed two-tone BLUE dome brooch. The center lighter blue rhinestone is encircled by a row of smaller alternating teal and dark blue colored stones; and an outer row of slightly larger alternating light and dark blue stones, with small round teal colored stones in between the larger stones.

WEISS mark is on the back in an oval plaque was first used in 1951, no copyright symbol dating this brooch between 1951 and 1955. (I have seen another similar in every respect except the colors are red & pink with a copyright symbol on the signature plaque).
