This Sarah Coventry Brooch measures 3 inches by 3 inches and has a gold-tone metal setting. It houses large stones, which I believe to be lucite. The middle stone is round and olive green with red specks and it is surrounded by 4 cherry red round stones. The outer large rectangular stones are multi-colored in shades of olive green, red, turquoise color and yellow. The colors all blend really beautifully. Marked ⓒSarah Cov on a gold-tone plaque on the back of the brooch in the middle, this pin is in excellent condition.
