Frequently Asked Questions

About Authenticity & Quality

How can I verify the authenticity of my diamond?

Every diamond comes with a GIA or HRD certificate number verifiable directly on the lab's official website. Diamonds also feature a laser-inscribed ID on the girdle for physical verification.

Is the gold actually tested before sale?

Yes. Every gold piece is tested using an XRF spectrometer and acid test by certified jewellers. Test results are recorded and kept on file before each shipment.

What does the warranty cover?

The 1-year warranty covers manufacturing defects such as stone loss due to setting failure or production damage. It does not cover normal wear and tear or damage from impact.
