Mohawkite is a rare rock consisting of a mixture of algodonite, domeykite, and arsenic-rich copper. It derives its name from the Mohawk Mine in Michigan, USA, where it was originally discovered. Mohawkite exhibits a range of colors, from brassy-yellow to metallic gray. The most coveted specimens are typically found embedded in white quartz matrix, making them highly sought-after for use in jewelry due to their striking appearance.

Kamacite is an alloy of iron and nickel, which is found on Earth only in meteorites. The proportion iron:nickel is between 90:10 and 95:5; small quantities of other elements, such as cobalt or carbon may also be present. The mineral has a metallic luster, is gray and has no clear cleavage although its crystal structure is isometric-hexoctahedral. Its density is about 8 g/cm and its hardness is 4 on the Mohs scale. It is also sometimes called balkeneisen. The name was coined in 1861 and is derived from the Greek root καμακ- "kamak" or κάμαξ "kamaks", meaning vine-pole. It is a major constituent of iron meteorites (octahedrite and hexahedrite types). In the octahedrites it is found in bands interleaving with taenite forming Widmanstätten patterns. In hexahedrites, fine parallel lines called Neumann lines are often seen, which are evidence for structural deformation of adjacent kamacite plates due to shock from impacts. At times kamacite can be found so closely intermixed with taenite that it is difficult to distinguish them visually, forming plessite. The largest documented kamacite crystal measured 92×54×23 cm (36.2×21.3×9.1 in).

Rudraksha is a sacred seed originating from the Rudraksha tree found in the Himalayan regions of Nepal, India, and Indonesia. With a history dating back thousands of years, it holds deep spiritual significance in Hinduism and is commonly used in prayer beads and jewelry. Its appearance includes distinctive grooves or facets, and the number of faces on each seed determines its rarity and spiritual potency.
