Whats the worlds most expensive veneer?

As of September 2021, the most expensive wood veneer in the world was generally considered to be Amboyna Burl. Amboyna Burl is derived from the burl wood of the Pterocarpus indicus tree, which is native to Southeast Asia. It is highly prized for its intricate grain patterns, rich reddish-brown color, and unique swirls and figures.

The high cost of Amboyna Burl is due to its rarity, as well as the difficulty in sourcing and working with the wood. It is often used for high-end luxury furniture, fine cabinetry, and decorative items.
