Bracelets

Based on what attracts you right now: color, property, or simply what feels right at the moment. Amethyst for serenity, Rose Quartz for self-love, Black Tourmaline for protection, Citrine for abundance, the choice is intuitive, from the gut.

They say the non-dominant hand is the receiving hand, drawing energy inward, suitable for stones of healing, peace, and self-love. The right hand radiates energy outward, suitable for stones of protection and abundance. Ultimately, the most important thing is to listen to your body; it knows best.

All gemstones love moonlight (please note that this should not be done during a solar or lunar eclipse).
You can also place them on the ground overnight (this is what I do before packaging them for shipment to you).
You can also place them on a windowsill for a few hours with gentle morning sunlight.
Frequency - rely on your intuition, whenever it feels right.
