Carnelian Agate tumbled

Pink Aventurine is a beautiful gemstone that accepts a fine polish. It is often cut into beads and used with jewelry. This is one of the several varieties of the mineral known as Aventurine, which is usually green. All Aventurine stones, including pink Aventurine, are recognizable by their sparkling or glittering effect.

Banded Carnelian is a semi-precious stone prized for its beautiful yellow, orange, or amber bands combined with white. This effect is created by combined layers of Carnelian and Agate, which are both varieties of the mineral known as Chalcedony. Most of these polished stones are mined and produced in Botswana.

Mookaite tumbled is a popular stone, valued for its highly contrasting patterns of brightest yellow, brown, orange, red, and maroon. Sourced in Western Australia, in the Carnarvon Basin, and extremely difficult to mine, mookaite tumbled can be cut, polished, and carved. It is often cut into beads and used with jewelry.

Tumbled pyrite tumbled has a metallic appearance and pitted finish. It resembles Hematite but has a golden/copper hue and is, generally, not as smooth. It is found in the USA, Italy, and Spain. Although easily tarnished, pyrite tumbled can be made into beads, figurines, and cabochons. Sometimes, it is made into jewelry

Petalite, also known as castorite, is a lithium aluminium phyllosilicate mineral LiAlSi4O10, crystallizing in the monoclinic system. Petalite occurs as colorless, pink, grey, yellow, yellow grey, to white tabular crystals and columnar masses. Occurs in lithium-bearing pegmatites with spodumene, lepidolite, and tourmaline. Petalite is an important ore of lithium, and is converted to spodumene and quartz by heating to ~500 °C and under 3 kbar of pressure in the presence of a dense hydrous alkali borosilicate fluid with a minor carbonate component. Petalite (and secondary spodumen formed from it) is lower in iron than primary spodumen making it a more useful source of lithium in e.g. the production of glass. The colorless varieties are often used as gemstones.
