So it's a fair statement to make that Korina Wood Gibson's are also some of Gibson's most valuable guitars. Korina is legendary as a tonewood, It is not overly expensive but it is rare. My theory on it's rarity is there aren't many lumber importers bringing it in to the country because there is simply not enough other uses for it. The guitar business is actually minuscule in the grand scheme of things. For most similar applications mahogany works just as well.
Mahogany is extremely plentiful readily available anywhere and inexpensive.
On this page there are many photos of Korina Wood also known as Limba. There are two varieties, Black Limba and White Limba. I have not been able to determine a noticeable difference in tonal quality or resonance between the two varieties.
