The bowl is a purple base glass and has 8 ruffles and a collar foot. The iridescence is just outstanding!! In fact it is considered electric. You can see vivid electric purples and blues along with some golds. The background is stippled and the back or underside is a plain back.
The bowl is in excellent condition as there are no cracks, nicks, chips, nicks or dings. The piece is unsigned but guaranteed to be vintage Imperial.
