Quality Assurance
Exceptional Jewellery. Uncompromising Standards.

At EMME Diamonds, true luxury goes beyond beauty. It lies in the authenticity of precious materials, the precision of craftsmanship, and the attention given to every detail.

From independently graded diamonds to verified gold purity and thoughtful aftercare, we ensure every creation meets the standards you deserve.

Internationally Certified Diamonds
Confidence in Every Diamond.

Every EMME diamond weighing 0.30 carats and above comes with an internationally recognised grading report from either the Gemological Institute of America (GIA) or the International Gemological Institute (IGI).
These independent gemological laboratories assess diamond characteristics using established grading standards, providing transparency and confidence in your selection.

UNDERSTANDING
GIA & IGI
CERTIFICATION
GIA - Gemological Institute of America

GIA is one of the world’s most respected authorities in gemology and the creator of the internationally recognised 4Cs of diamond quality: Cut, Colour, Clarity, and Carat Weight. Its independent grading reports provide an objective assessment of a diamond’s characteristics.

IGI - International Gemological Institute

IGI is a globally recognised gemological laboratory specialising in diamond, gemstone, and jewellery assessment. Its independent grading reports evaluate key diamond characteristics, including the 4Cs, helping customers make informed purchasing decisions.

Quality Assurance for Smaller Diamonds
Every Detail Deserves Attention.
For jewellery featuring non-individually-certified diamonds below 0.30 carats, EMME provides a complimentary jewellery report from a reputable gemological laboratory. This additional documentation provides an independent assessment of your jewellery, extending our quality assurance standards to even the smallest diamond creations.
Precious Metals & Hallmarking
Precious Materials. Verified Purity.

EMME’s signature creations are crafted exclusively in 14K to 22K solid gold, combining lasting beauty with the enduring value of precious metals.
As part of our quality control process, every gold creation undergoes independent third-party purity testing and is stamped according to its verified gold purity.
For those seeking an alternative precious metal, bespoke silver jewellery is also available upon request.

Independent Jewellery Valuation
An Added Layer of Confidence.

Your jewellery carries both personal and material value. For additional peace of mind, EMME can arrange an independent third-party jewellery valuation certificate for insurance purposes upon request.

This documentation may assist you in obtaining appropriate insurance coverage for your treasured jewellery.

Complimentary Resizing & Size Replacement
A Perfect Fit, With Our Compliments.

We believe the care you receive should be as exceptional as the jewellery itself.

Eligible EMME purchases include one complimentary resizing or size replacement within 12 months of completion, along with free two-way postage for your convenience.

It’s our way of ensuring your jewellery continues to feel just right, long after it becomes yours.

This service is subject to purchase and design eligibility.
