Mahogany

Mahogany has a straight, fine, and even grain, and is relatively free of voids and pockets. Its reddish-brown color darkens over time, and displays a reddish sheen when polished. It has excellent workability, and is very durable. Historically, the tree’s girth allowed for wide boards from traditional mahogany species. These properties make it a favorable wood for crafting cabinets and furniture.

Much of the first-quality furniture made in the American colonies from the mid 18th century was made of mahogany, when the wood first became available to American craftsmen. Reference: Wikipedia
