6.3 x 4.7 x 2.8 cm. This piece consists of at least three types of cerussite: colorless, lustrous, larger blades; smaller, chrome-rich, pastel yellow-green blades; and finely reticulated, snowflake-like blades. Ex. Wagoner and George Elling Collections.
5.7 x 3.3 x 3.0 cm. A fine cluster of three, blocky and lustrous, midnight-blue azurite crystals perched atop elongated malachite-rich matrix and nicely complimented by glassy cerussite crystals from the famous and now-closed Tsumeb Mine. The azurite crystal faces have a mirror finish and the large crystal is 1.7 cm. Ex. George Elling Collection.
2.7 x 2.6 x 1.5 cm. A V-twinned cerussite crystal from the Collins Vein at Tiger, Arizona. This adamantine lustre, partially gemmy crystal has textbook twinning, a sharp notch and striations. Ex. Dave Stoudt Collection.
2.8 x 2.7 x 1.9 cm. A complete, reticulated crystal of cerussite from the famous Tsumeb locality. It has a glassy termination, and is set in a thin sheet of contrasting matrix (which appears to be degraded cerussite). This crystal probably dates back to the 1960s.
5.9 x 5.1 x 3.3 cm. This specimen has an unusual type of cerussite with discrete coloration due to chromium rich content, and the sharp crystals reach .7 cm across. Studded on the cerussite are bright orange prisms of crocoite, to .3 cm across. Ex. Dr. Edward David Collection.
1.8 x 1.7 x 1.5 cm. A fine, single crystal of six-ling twinned cerussite colored slightly reddish by either hematite or copper inclusions. Copper is likely, since small specks of malachite are dotted on the outside of the crystal. Ex. Rice Northwest Museum and Esker Mayberry Collections.
10.0 x 7.9 x 5.0 cm. A fine Tsumeb cabinet specimen of four ball-like, cyclically-twinned cerussite crystals set on well trimmed solid, coral-like, forest-green rosasite crystal matrix. The cerussites and rosasite are richly dusted with sparkly, calcite micro-rhombs. Ex. Rob Smith Collection.
4.2 x 4.0 x 2.7 cm. This is a rare combo specimen of creamy crystals of smithsonite that have wrapped themselves around a glassy, gemmy compound crystal of cerrusite.
7.8 x 5.5 x 2.5 cm. This superb matrix specimen is studded with lustrous chrome-cerussite crystals to .7 cm across. Ex. Martin Zinn Collection.
6.5 x 5 x 3.3 cm. Sharp crystals of this very rare chromian-rich, bright yellow, variety of cerussite. Ex. Martin Zinn Collection.
8.8 x 8.3 x 4.2 cm. A superb Tsumeb combination specimen of at least 12 lustrous, colorless, cyclically-twinned cerussite crystals set on a robust, sintered, latticework matrix that is richly covered with sparkly, tan to orangey mimetite microcrystals. The largest twin is 3.3 cm across. Ex. Rob Smith Collection.
2.5 x 1.9 x 0.4 cm (largest). A fine, old-time, 7-piece set of classic cerussite crystals from the famous Mammoth-St. Anthony Mine at Tiger, Arizona. The striking variety of crystal forms include a reticulated snowflake, V-twins, a blade, a tabular crystal and cyclic twins on these adamantine, gemmy crystals. Ex. John Ydren Collection.
10.5 x 5.7 x 4.3 cm. Multi-hued green, spherical malachite, to 1.5 cm across is accented with a few crystals of colorless, adamantine, cerussite. Ex. Harold Urish Collection.
7.4 x 5.4 x 3.9 cm. This is a superb specimen with a very 3-dimensional cluster of glassy and transparent cerussite. The leached galena forms the matrix for a cluster of cyclic-twinned, gemmy, colorless cerussite crystals with adamantine luster. The cerussite crystals reach 3 cm in length and when the crystals are viewed head on, the intricacies of the cyclic twinning become even more evident. Ex. Harold Urish Collection.
5.0 x 3.5 x 3.1 cm. A gorgeous, 2.0 cm, very finely reticulated, "snowflake" cerussite aesthetically set upright on a dense bed of "wet-look", apple-green pyromorphite prisms from a very small, 2007 find at the famous Daoping Mine of China.
