Spinel
- Locality: Gon Deposit, near Timpton River, Lena River Valley, Aldan, Aldan Shield, (Eastern Siberian, Russia
- Size: thumbnail, 2.6 x 2.4 x 2.3 cm
- Spinel
- This equant, sharp spinel crystal is free of damage, measuring 2.25 cm in each dimension, and beautifully terminated. It is totally complete except for a few minor contacts of attached matrix on back, and floats freestanding on a pedestal of natural matrix! It has a rich "satiny" lustre, characteristic of pocket-growth crystals that have never been covered by other rock, or calcite infill which has to be removed with acid. This locality historically produced spinels of this calibre, but I had never seen one of such size and in any case they came out 20 years and more ago. This new find at the same old locale has provided us a small new supply of these spinel classics. What is nice , though, is that the overall quality for this combination of size and crystal habit of spinel has not been surpassed in the meantime - they stand as important spinels, not just as interesting locality classics, in other words.
