The world of diamonds can be extremely bright, but stepping into it can also be frightening. Unlike a perfume, where the main concern is fragrance, diamonds come with different sets of concerns that consider not only beauty but also value. It consists of various factors such as the 4C’s, its brilliance, light, and many more things.

At The Diamond Factory, we believe that transparency is essential when it comes to interacting with our customers. Therefore, each TDF diamond proudly bears the BIS hallmark. We also provide certification from IGI, EGL, SGL, GIA, and our in-house certificate to ensure quality and authenticity.

The Importance of Diamond Certification:

A diamond certification is a detailed report of quality assurance issued by an independent gemological laboratory. Purchasing a diamond without knowing its certificate is like buying a car without knowing its mileage.

Certificates assure you of the authenticity of diamonds and empower you to make informed decisions. It protects you from potential fraud and misleading characteristics.

A certified diamond is a genuine diamond, not a replica of the original one. Certifications help decode the 4Cs of diamonds, which include carat, cut, clarity, and colour. Each C significantly influences the quality of the diamond. These assured diamonds hold a great resale value as their quality is documented.
