Rick, if you can buy real stingray cord, please tell me where to find it.
In my sourcing experience, all stingray skin sold as real is actually faux .....probably embossed cowhide.
One reason for it's scarcity is that it's exceedingly tedious to process.
Here is a photo of real stingray leather. It's all in the tiny details, most of which you can see in the texture.
Such as the various sizes and randomness of the bumps.
There is no way you could isolate a section and see that bump pattern reproduced anywhere else on the fish skin.
Visually, up-close, it's possible to identify most of the simulated stingray skin.
Real stingray is a rich treat for the fingers and eyes.
