A third Pakistani discovery begs notice here, as it did also at <strong>the</strong> 2012 Tucson Show,<br />
where a couple of dealers showed up with top-of-<strong>the</strong>-l<strong>in</strong>e specimens of elbaite with<br />
albite recovered <strong>in</strong> summer 2011 from two large pegmatite pockets at Stak Nala, Skardu<br />
district, Gilgit-Baltistan (Gilgit-Baltistan is <strong>the</strong> prov<strong>in</strong>ce formerly called “Nor<strong>the</strong>rn<br />
Areas”). Elbaite from Stak Nala is dist<strong>in</strong>ctive enough that <strong>the</strong> occurrence has become<br />
quite well known <strong>in</strong> <strong>the</strong> West s<strong>in</strong>ce <strong>the</strong> very first crystals came out <strong>in</strong> <strong>the</strong> early 1980s;<br />
systematic recovery efforts over <strong>the</strong> next 20 years produced thousands of specimens, but<br />
by <strong>the</strong> start of <strong>the</strong> new millennium, production had almost ceased. “Stak Nala” elbaite<br />
specimens typically show lustrous, lightly striated, stocky crystals, many of <strong>the</strong>m doubly<br />
term<strong>in</strong>ated, featur<strong>in</strong>g complex color-zon<strong>in</strong>g but mostly dark green, with bladed white<br />
albite crystals. In a March 10 update to <strong>the</strong> site of Your M<strong>in</strong>eral Collection<br />
(www.yourm<strong>in</strong>eralcollection.com), many f<strong>in</strong>e elbaite/albite specimens, to small-cab<strong>in</strong>et<br />
size, from <strong>the</strong> new strike are posted. <strong>The</strong>y show dark green, short-prismatic crystals,<br />
some with pale green or colorless zones near <strong>the</strong> tips, to 3.5 cm long, with albite blades<br />
crowd<strong>in</strong>g and jumbl<strong>in</strong>g around <strong>the</strong>m. It’s very good to see fresh material com<strong>in</strong>g at last<br />
from this contemporary-classic occurrence—Pakistan’s best (or at least most prolific) for<br />
tourmal<strong>in</strong>e.<br />
Elbaite, center crystal 2.4 cm, from San Piero <strong>in</strong> Campo, Elba,<br />
Tuscany, Italy. Dem<strong>in</strong>eralia specimens and photo.<br />
Speak<strong>in</strong>g of elbaite tourmal<strong>in</strong>e…you know of course that <strong>the</strong> type and namesake<br />
locality for this species is <strong>the</strong> Italian island of Elba, where pockets <strong>in</strong> pegmatite seams <strong>in</strong><br />
<strong>the</strong> Monte Capanne granite have produced f<strong>in</strong>e, gemmy, color-zoned crystals of elbaite<br />
for a couple of centuries now, although with greatly dim<strong>in</strong>ish<strong>in</strong>g frequency dur<strong>in</strong>g all of<br />
our lifetimes. <strong>The</strong> granite crops out all over <strong>the</strong> western half of <strong>the</strong> island, but most<br />
collect<strong>in</strong>g has taken place on hillside exposures of pegmatite below villages such as San<br />
Piero <strong>in</strong> Campo: a magical name if we’ve looked at enough old labels. In a February<br />
update to <strong>the</strong> site of his Dem<strong>in</strong>eralia dealership (www.dem<strong>in</strong>eralia.com), Emanuele<br />
Mar<strong>in</strong>i offers pretty, gemmy, s<strong>in</strong>gly term<strong>in</strong>ated, thumbnail-size elbaite crystals from San<br />
