Description Raquelle is a Rhodochrosite sloth from Jewelimals. She is one of co-workers from Happiness Hills Mortgage.

Rhodochrosite is a manganese  carbonate mineral  with chemical composition MnCO 3. In its pure form (rare), it is typically a rose-red colour,[5]  but it can also be shades of pink to pale brown. It streaks  white,[6]  and its Mohs hardness  varies between 3.5 and 4.5. Its specific gravity  is between 3.45 and 3.6.[7]  The crystal system of rhodochrosite is trigonal , with a lattice structure and cleavage  in the carbonate rhombohedral system . The carbonate ions (CO2−
3) are arranged in a triangular planar configuration, and the manganese  ions (Mn2–) are surrounded by six oxygen ions in an octahedral arrangement. The MnO6 octahedra and CO3 triangles are linked together to form a three-dimensional structure. Crystal twinning  is often present. It can be confused with the manganese silicate rhodonite , but is distinctly softer.[8]  Rhodochrosite is formed by the oxidation of manganese ore , and is found in South AfricaChina , and the Americas .[6]  It is one of the national symbols of Argentina .

Rhodochrosite forms a complete solid solution  series with iron carbonate (siderite ). Calcium  (as well as magnesium  and zinc , to a limited extent) frequently substitutes for manganese in the structure, leading to lighter shades of red and pink, depending on the degree of substitution. This is the reason for the pink color of rhodochrosite.
