The raw materials for gemstone dice are natural gemstones with different patterns and colors. As an OEM factory, we have more than 100 different kinds of raw gemstones for clients to choose for their custom orders. Gemstone dice is a high value handmade item, so small MOQ like 50 sets can be accepted. Each order will take 4-5 weeks to process if quantity is not that big. Gemstone dice is fragile, so we suggest players to roll them on a soft surface, like a soft velvet dice tray. Of course, it is a great choice for collection.
