We ordered these Rainbow Moonstone pendants months ago but with COVID-19 problems in India and they finally arrived!
This style has a big fan base as guys and gals like it. This style (and we have it in heaps of different crystals e.g. scolecite, selenite, carnelian, amethyst, aquamarine, black tourmaline, clear quartz etc) is silver-coloured metal on a base metal probably brass. There is no nickel.
The nurturing energy this crystal will give you comfort and guidance in difficult times. And it helps you fertility for a baby or manifesting a project.
