All of our Tru Stone dice are crafted using a variety of crushed gemstones that are bound together with resin resulting in a stunning set that is 80% semi-precious stone and 20% resin. This leaves us with a gorgeous dice that combines the beauty and uniqueness of natural stone with the strength and durability of resin. This process also allows us to utilize the same C&C machines and milling methods we use to create our precision metal dice. The final product is a perfect amalgamation of natural beauty and machine-like precision, allowing you to settle in to your game and roll with confidence and pride.
