The total area of the piece of jewelry is 33 square centimeters.
The area of the rectangle is 9 cm x 3 cm = 27 square cm.
The area of each triangle is (1/2) base x height = (1/2) x 2 cm x 3 cm = 3 square cm.
Since there are 2 triangles, the total area of the triangles is 3 cm + 3 cm = 6 square cm.
Therefore, the total area of the piece of jewelry is 27 square cm + 6 square cm = 33 square cm.
