Aaron's Breastplate Real Stones Recreation. All Real stones are used which makes this Breastplate more expensive, but more realistic. Green Jade is used in place of the green Emerald and Natural agate for peridot to keep the price down. There is an information chart on the back. There is a pocket in the back for the Urim & Thummim which comes free with this set. There is a chain so you can put it around your neck. Great for demonstrations.
