Yes. It looks like a crystal necklace when the light is off. Twist it on when you want the glow, and twist it off when you want to save battery.

The light is soft and gentle, around 6-9 lumens. It is bright enough to show the color and patterns inside the crystal. It looks best indoors, in shade, or at night.

Your crystal will match the product photos, but the exact color and patterns will be its own. That is what makes each one special. You also have 30 days to return or exchange it.

We work with trusted crystal partners around the world. Each stone is checked with light, then cut, polished, and set into the pendant. Learn more about our crystals.
