Confidence in the trustworthiness of your jeweler
The “new” and fifth C is for confidence. As a buyer, you need to have confidence in the product you want to purchase: That it has been mined, processed, and traded according to socially, ecologically, and ethically acceptable conditions.
A trustworthy jeweler will hand you a certificate for every diamond, proving that his gemstones are obtained from trustworthy sources. This is, of course, a standard for all stones and jewels purchased at HIRMIZ in Ludwigsburg and something you can confidently rely on!
