<dd>The götzenite blades (to ~ 12 mm) look like old ivory. Ex Ron Waddell. MOB coll.</dd>
<dd>The label says "götzenite" and I thought this was my best. But I couldn't ID the orange micaceous looking flakes (top). So I tested for polylithionite with UV. No glow. But the götzenite (bottom) did glow. Strong lemony white (SW). Similar to elpidite from the Poudrette pegmatite.</dd>
<dd>But it has now been verified (EDS) as götzenite by Tony S at ROM! Score one for Ron. The fluorescence is a mystery. Other götzenites from MSH do not fluoresce.</dd>
<dd>Sept 2009: Updated using stacking and added stereo and "backside" views.</dd>
<dd>As for the "micaceous" yellowish flakes, my old friend H. Cl tells me that they are calcite. So now it makes sense. This specimen is from marble xenolith - the usual hiding place for götzenite at MSH.</dd></dl></dd></dl>
