GenericAlloy and Crystal Changing Colour Ring for Women (Blue & Silver)

Works as it claims. Colour does change

Color change is not automatic

Cheap Chinese stuff at high price. Product says alloy. But it's a copper ring coated with silver paint. Seller can't be reached as it's Chinese based and Amazon seeks no interest in a feedback. Ring costs ₹300 which i would like as a refund.

I received a wrong product which looks like girly wear.It looks like just a stone kept in the ring.

its changing colour according to room temperature when I sit in A/C room its colour change to green
