Looooooooove Merkaba stars 💎🌟 
The Merkaba is an extremely powerful symbol. It is a combination of two star tetrahedrons, it's also often spelled Merkabah, and translates literally to light, spirit, body. 
It is the divine light vehicle allegedly used by ascended masters to connect with and reach those in tune with the higher realms. 
I have them in Rhodonite, Amazonite, lapis and Chevron Amethyst these are all approximately 3.5cm and are priced at £14.95 each
