Asked about this piece
Can I wear this daily?
That is what it is for. Every stone we set is chosen for hardness as well as color, and resetting is included for life if you ever wear it down.
“The color is stranger and better in person. I have worn it every day since.”

- Daily wear
- Wear it daily for a lifetime; it will scratch everything before anything scratches it.

- Warm water, a drop of dish soap, a soft brush. Ultrasonic is fine.
