Dear Zuzana,
Thank you very much for placing your order and for your review.
We are sorry to read that the stone of your ring no longer shines beautifully. That is obviously not the intention! A 2-year warranty applies to all TI SENTO jewellery.
Could you please send an e-mail to wecare@tisento with your order number and a photo of the jewellery?
Then we will be happy to help you find a suitable solution.
Thank you in advance and have a lovely day!
Kind regards,
Team TI SENTO
