Opal ranges from clear through white, gray, red, orange, yellow, green, shore, blue, magenta, rose, pink, slate, olive, brown, and black. Of these hues, the reds against black are the most rare and dear, whereas white and greens are the most common; these are a function of growth size into the red and infrared wavelengths&#8212;see precious opal. Common opal is truly amorphous, but <i>precious opal</i> does have a structural element. The word <i>opal</i> comes from the Latin <i>opalus</i>, by Greek <i>opallios</i>, and is from the same root as Sanskrit <i>up&#225;l&#225;[s]</i> for "stone", originally a millstone with <i>up&#225;r&#225;[s]</i> for slab.<sup class="reference" id="cite_ref-San_3-0"><span>[</span>4<span>]</span></sup> (see Upal). Opals are also Australia's national gemstone.</p> <p>Opal is one of the mineraloids that can form or replace fossils. The resulting fossils, though not of any extra scientific interest, appeal to collectors.</p> <p>Besides the gemstone varieties that show a play of color, there are other kinds of common opal such as the milk opal, milky bluish to greenish (which can sometimes be of gemstone quality); resin opal, honey-yellow with a resinous luster; <b>wood opal</b>, caused by the replacement of the organic material in wood with opal<sup class="reference" id="cite_ref-5"><span>[</span>6<span>]</span></sup>; menilite brown or grey; hyalite, a colorless glass-clear opal sometimes called Muller's Glass; geyserite, (<span class="mw-redirect">siliceous sinter</span>) deposited around <span class="mw-redirect">hot springs</span> or geysers; and <span class="mw-redirect">diatomite</span> or diatomaceous earth, the accumulations of diatom shells or tests.</p> <font class="font2">This article is licensed under the <a href="http://www.gnu.org/copyleft/fdl.html" class="external text" title="http://www.gnu.org/copyleft/fdl.html" rel="nofollow" target="_blank">GNU Free Documentation License</a>.
