<p>[QUOTE=&quot;Bronwen, post: 11370302, member: 5833&quot;]A good question &amp; one to which I have no definite answer.&nbsp; I rarely consult the Miller/Jarrett collectors&#039; guide to cameos, but did check (4th edition) because I know it has info on contemporary engravers &amp; methods.&nbsp; It looks like modern automated techniques are used for hardstone pieces produced as multiples, but there is no mention of laser or ultrasound being used on shell, perhaps because it is much more fragile, although lasers can be calibrated delicately enough for use in ophthalmology...&nbsp; I think Snow White &amp; her little friends were hand cut.&nbsp; [USER=83302]@Snowman Cometh[/USER] is that your understanding?[/QUOTE]</p><p><br /></p>
