Continuing from where we left off would like to state the obvious that Leather is a natural product which will age with time yet possess one common trait which is regardless of the caring procedures, they preserve their core characteristics. The leather surface fades naturally over time thus showing signs like difference in grain, texture and pigmentation but highlighting the authenticity of the product.
As a beginner in the Leather world, my knowledge is pretty confined and I am still unable to differentiate genuine leather from a synthetic one. They say it will come with time, but in hindsight I know that the technological and manufacturing advancement in leather tanning and synthetic processing will make it even more difficult for me or anyone of us for that matter to differentiate. Having said that I mean the experts community does not infuse the methods to decipher genuine leather from synthetic as that wisdom is concealed within with no intent to share with the outside world.
