[Kruxly]

Username: Kruxly
Name: GSK These Holy Wings // Seraphinite
Name Meaning: Taken from wikipedia:

Seraphinite apparently acquired its name due to its resemblance to feathers due to its chatoyancy. Seraphinite is named after the biblical seraphs or seraphim angels. With some specimens the resemblance is quite strong, with shorter down-like feathery growths leading into longer "flight feathers"; the resemblance even spurs fanciful marketing phrases like "silver plume seraphinite." Seraphinite is generally dark green to gray in color, has chatoyancy, and has hardness between 2 and 4 on the Mohs scale of mineral hardness.

Name Meaning: See below! <3
Gender: DFAB
Prompt: Paraíba tourmaline is an incredibly rare and vivid gemstone first found in Paraíba, Brazil in the 1980s. While there are varying colors, the most common is a shade of blue-green. This coloration is due to the gemstone's copper content; oxidized copper (copper exposed to oxygen) will take on a turquoise hue.
