Quartz

Here's a killer, 360-degree small cabinet specimen featuring exceptionally limpid, very glassy crystals, dominated by an impressive central crystal with a strikingly sharp, undamaged, angular termination. The main crystal shows outstanding clarity and brilliance, with a clean, reflective surface that gives the piece strong visual impact from every angle. Several smaller, well-formed companion crystals are attached at the base.

The exceptional transparency and lustre of these crystals place this piece well above average for the species, making it especially appealing to collectors who value purity of form and optical quality. The specimen comes from the Mexican–South American collection of Robert Yeoman. Its combination of pristine termination, superb glassy character, and all-around display quality makes this a standout cabinet specimen suitable for any high-level mineral collection.
