Topaz on Muscovite
Alabashka pegmatite field, Yuzhakovo Village, Ekaterinburgskaya (Sverdlovskaya) Oblast', Middle Urals, Urals Region, Russia
Cabinet, 9.4 x 7.7 x 5.8 cm
A 1.5 cm blue topaz on a really fine cluster of sharp hexagonal muscovite crystals, from this classic locality that has been important since the early 1800s as a maor source of gem topaz. Matrix specimens are few and so I will pardon a repair at the right price. Note that this topaz is repaired back onto the specimen, although we are fairly confident this is where it originally grew. Perhaps, though, this specimen is even more interesting as an example of a Mursinka muscovite....in person these have a rich lavender/purple color and are MUCH more interesting geometrically than the photos can convey.
