Product Quality Guarantee

When shopping on the WILLS JEWELLERY website, you can enjoy the following quality guarantees:

(1) International Certificate Recognition

  • All diamonds (main stones) come with internationally recognized certificates. Customers can use the certificate number to visit the official website of the issuing organization to check the details and authenticity of the certificate, ensuring its validity. For example: GIA certificates can be verified on the following GIA official website (http://www.gia.edu/report-check-landing).

  • When purchasing diamonds, customers can use a magnifying glass to observe the laser-etched number on the diamond's girdle and compare it with the number on the certificate to ensure the diamond matches the certificate. For GIA, currently, all diamonds under 1 carat have laser inscriptions. Diamonds of 1 carat or more may not necessarily have them, as GIA certificates for diamonds over 1 carat include a clarity characteristics diagram, allowing customers to use a 10x magnifying glass to observe the features of the inclusions in the diamond to confirm if it matches the diamond on the certificate.

  • All gemstone (main stone) jewelry purchased in our store that is 1.5ct or above comes with an accredited gemstone certification.

(2) Rigorous Quality Inspection
WILLS JEWELLERY's professionals will carefully inspect the quality of the products before delivery to ensure that customers receive high-quality products.


(3) Diamonds

(4) WILLS 5C – Critique
WILLS JEWELLERY's criteria for selecting diamonds go beyond the 4C. Diamonds are natural minerals that cannot be fully described in words. Our appraisers personally use instruments to select the most brilliant diamonds for customers, ensuring that the highest quality is chosen within the 4C scale, providing a professional critique of the diamond's quality and informing customers of aspects worth considering beyond the certificate.
