YAZ & Co works exclusively with lab-grown diamonds created in controlled environments using advanced technology. They share the same physical and chemical properties as natural diamonds, and their origin is always disclosed before purchase.

Our selection standard

• Cut — Excellent, for optimal brilliance, proportion and balance
• Clarity — VS to VVS, where inclusions are not visible to the naked eye
• Colour — EF, a clean and refined white
• Light performance — assessed individually before a stone joins a collection

All YAZ & Co jewellery is crafted in 18K gold and available in yellow, white and rose.

Selecting the correct ring size helps ensure comfort, balance and security. You can find yours by measuring the internal diameter of a ring that already fits, or the circumference of your finger in millimetres. When your measurement falls between two sizes, choose the larger.

Selected designs are available in custom sizes on request. Complimentary sizing assistance is available at the boutique.
