Each of these dream Amethyst donuts is approximately 1.25" in diameter. It's not top grade, (hence the super affordable price) but each piece has nice color.
Amethyst is one of the most highly regarded stones for metaphysical healing. The vibration works with your third eye and crown chakras to open higher states of meditation and consciousness. It promotes inner peace and contentment and is regarded as a stone of sobriety and inner strength.
I love using these as sphere stands, but can also be used in jewelry making and other DIY projects.
