The above grips are of true Cocobolo wood.
One can identify true Cocobolo wood by that specific browny-red chestnut color and the depth and figure and inherent beauty of the grain. Good examples of Cocobolo are getting scarce in today's profit-generated world and the best of them are commanding higher and higher prices. As such in cost-cutting measures, fake impostor woods of similar-appearance and sources of lesser quality Cocobolo are becoming popular and ubiquitous.
Padauk wood is the most prominent source of fake Cocobolo and is now being slyly introduced as true "Cocobolo", under the legal loophole that "Cocobolo" by definition is just an "appearance" similar to true Cocobolo wood and as such, is a fully-legal label as nobody can patent a species per se.
For proof of this assertion, just look at the majority of SS CZ-75B grips pictured on the internet labelled as Cocobolo wood. The vast majority are of the half-checkered "Cocobolo" variety of Padauk, the much more purple-red coloured wood, the current Chinese impostor and leader in the extinction of true Cocobolo.
Padauk is much cheaper to produce and thus profits are huge and really, the gaudy color is not worthy of our guns.
So in seeking the right look of Cocobolo grips for your prized CZ-75B of polished SS or not, do your homework as a consumer. A set of grips that are way too orange or too purple or red are not the true Cocobolo wood - labelled as such or not - that truly complements the look of of your prized CZ-75B.
