Rose Quartz Bracelet Why Does My Rose Quartz Bracelet Keep Turning White Every Time I Wear It?

Why does my rose quartz bracelet keep turning white every time i wear it? - rose quartz bracelet

I have a bracelet made of pink rose quartz natural quartz (one kind of spike trains). Originally a soft pale pink, but 2 days later, he turned white, as I called it. And today, I let my friend and was wearing pink! It's very frightening. And when I see him again become white.
Someone please tell me why this happens?
PS I No, I was hanging in the sun ...
