This is a rare 7.63-gram Impactite end cut specimen from the impact structure located near the village of Karlinskoye in the Ulyanovsk Oblast of Russia.  It is generally referred to as the Karla crater (Russian: Карлинский кратер). Its dimensions are 46x38x7 mm. 

The Karla crater, not to be confused with the Kara crater, is situated in the Ulyanovsk Oblast, near the village of Karlinskoye, not far from the city of Ulyanovsk. It is a confirmed meteorite impact structure with a diameter of approximately 10 kilometers (6.2 miles) with the age of the impact is estimated to be around 5 ± 1 million years old, placing it in the Pliocene epoch. The crater is considered exposed at the surface, and it features a complex structure with a central uplift composed of Paleozoic sediments and Archean crystalline basement rock, surrounded by a collapsed disruption cavity filled with breccia and lake deposits.

This is a rare 21.69-gram Kamensk Crater Impactite end cut specimen from the impact crater located 10 to 15 kilometres (6.2 to 9.3 mi) to the north of Kamensk-Shakhtinsky town in Rostov Oblast, Russia. Its dimensions are 57x43x12 mm. 

Kamensk crater is 25 km (16 mi) in diameter and the age is estimated to be 49.0 ± 0.2 million years old (Eocene). The crater is not exposed at the surface.  It may have formed at the same time as the smaller and nearby Gusev crater. Although not a meteorite, impactites are directly linked to them and their impacts and are probably going to be one of the rarest collection pieces you'll ever own.

The Gold Hill Wash Prospect, part of the Clifton-Gold Hill Mining District, is known for its rich mineral resources, including jarosite. This mineral is part of the larger group of minerals found in the area, which also includes limonite.

The Gold Hill Mine, operated by the Western Utah Copper Company in the early 20th century, was significant for its arsenic deposits, although it closed after World War I. The mine's portals and shafts have since been sealed by the state of Utah.

This specimen from the Gold Hill Mine is a matrix covered with minute jarosite crystals.  This specimen is an interesting addition to any mineral collection.

Pyromorphite (lead chloro-phosphate) was a common mineral of the oxidized zone of the Broken Hill orebody, and exceptional specimens of various crystal forms and colors were found. Some examples were yellow and some brown, while others were green. Their crystal habits varied from almost needle-like to thick barrels. This example illustrates one of those forms – barrel-shaped, six-sided, clove-brown crystals.

This hard to acquire specimen is in good condition.  A rare and really beautiful specimen. Would be a great addition to any new or existing collection.
