&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{stub}}&lt;br /&gt;
&lt;br /&gt;
A [[gemstone like compound]] that has high performance in terms of some metric that is to be used as structural material in [[metamaterial]]s.&lt;br /&gt;
&lt;br /&gt;
Some of the the materials maximally possible performance is sacrificed in order to &lt;br /&gt;
* gain material amazing properties that otherwise would not be possible.&lt;br /&gt;
* avoid the necessity of many other material alltogether&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Performance metrics may be things like:&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;0th derivative of energy&amp;#039;&amp;#039;&amp;#039; ~~ toughness (in therms of the energy given by stress integrated over strain till irreversible damage)&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;1th derivative of energy&amp;#039;&amp;#039;&amp;#039; ~~ ultimate tensile strength&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;2nd derivative of energy&amp;#039;&amp;#039;&amp;#039; ~~ stiffness&lt;br /&gt;
* material density (in mass per volume) &lt;br /&gt;
* thermal conductivity (or its inverse)&lt;br /&gt;
* …&lt;br /&gt;
&lt;br /&gt;
