First we need to understand what Mahogany wood is :
"Mahogany is a straight-grained, reddish-brown timber of three tropical hardwood species of the genus Swietenia, indigenous to the Americas and part of the pantropical chinaberry family, Meliaceae. Mahogany is used commercially for a wide variety of goods, due to its coloring and durable nature"
Then why so scares to find
"By the mid 1800s, good lumber was becoming rare. By the late 1800s, the species had been logged into genetic impoverishment and commercial extinction. Today there are still a few trees, but they are extremely rare and should not be used as such usage will encourage harvesting and the ultimate end of this species"
