It was a genuine veneer, yes.
Here is an AI overview: Golden Madrone burl veneer is a genuine veneer. It's made by slicing thin sheets of wood from the Madrone tree, specifically from the burl formations (knotted growths) of the tree. These veneers are known for their striking grain patterns, rich colors, and durability, making them a popular choice for high-end furniture, cabinetry, and other decorative projects.
As to "few remaining genuine veneers" there are still quite a bit more than a few offered on SQ2. Actually, there are only a few "replica' veneers. 2 actually. Replica Bubinga and Replica Rosewood. There are several things such as Tribals, and others that are engineered finishes, but aren't "replicating" a bona fide veneer.
Genuine veneers currently available:
African Marble (Marblewood, Per Mark Eldridge)
American Walnut
Birdseye (Amber, Azure, Cherry, Maple)
Ebony
Elder Tree
Natural
Nussbaum HiLite
Nussbaum ProLite
Scandinavian Birch
Silky Oak
Vintage (Amber, Azure, Onyx)
There are also some Roots and Burls that can be either naturally occurring or engineered based on my quick internet research.
So the wrap this up, we have 2 replica veneers. Apparently 16 genuine veneers and then a number of creations that aren't replications of anything, plus a few more that may or may not qualify as natural veneers.
