What type of mahogany is on offer? I understand there are several types.

The Mahogany Offered through Green World Lumber is true Genuine Mahogany – Swietenia macrophylla. Not to be confused with cheaper imitations, such as Philippine Mahogany, African Mahogany and Royal Mahogany. Swietenia macrophylla is what most consider to be the real and true species when referring to “Mahogany.”
