<p>[QUOTE=&quot;blooey, post: 1233562, member: 12007&quot;]I&#039;m afraid I can&#039;t teach you how to recognize real tortoiseshell over the internet, all I can suggest is that you begin your study of the material by purchasing some that you know to be real. When you have a known sample, examine the dissolution of colour at the edge of the transition from dark to light using a low powered loupe.</p><p>You will notice a powdery or granular appearance. This cannot be faked, other than by using colour Xerox prints of actual shell. </p><p><br /></p><p>Back in the era when your case was made, the maker would not have had access to artificial shell ..and why would he/she bother? Tortoiseshell was both inexpensive, plentiful and the most versatile &quot;plastic&quot; material known, both in the east and the west.[/QUOTE]</p><p><br /></p>
