Diamond Guide

Choosing a diamond goes beyond size or sparkle.
At YAZ&Co every stone is evaluated according to precise standards that ensure balance, brilliance, and refined craftsmanship.

We exclusively use lab-grown diamonds, carefully selected to meet our requirements in clarity, proportion, and light performance.

Lab-Grown Diamonds
YAZ&Co works with lab-grown diamonds created in controlled environments using advanced technology.

Each stone is individually assessed before being approved for our collections, ensuring it aligns with our standards of quality and consistency.

The 4Cs
Cut
Cut determines how a diamond reflects light.
We select Excellent Cut only to ensure optimal brilliance and balance.

Clarity
VS – VVS
High clarity grades with inclusions that are not visible to the naked eye.

Color
Carefully selected color grades to maintain a clean, refined white appearance.

Carat
Carat refers to weight.
At YAZ&Co, harmony between the stone and the design is always prioritized over size alone.

Craftsmanship
All YAZ&Co pieces are crafted in 18k gold and undergo a final quality inspection before release.

Authentication
Each piece is accompanied by an official YAZ&Co Authenticator including the stone’s details and a unique serial number.

An IGI certificate can be provided upon request for an additional fee.

Warranty
All pieces are covered by a one-year warranty against manufacturing defects.

The warranty does not cover loss of stones, accidental damage, or misuse.
After-warranty maintenance services are available upon request, subject to evaluation.
