Frequently Asked Questions

Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds share identical chemical, physical, and optical properties with mined diamonds. Hardness measures 10 on the Mohs scale, matching natural diamond durability.

Why is IGI certification important?

IGI certification provides independent verification of the diamond’s 4Cs. Buyers receive documented proof of authenticity and quality grading.

How long does a custom engagement ring take?

Most custom engagement rings are completed within two weeks, including CAD approval and final hand finishing.

Do lab-grown diamonds hold value?

Market pricing differs from mined diamonds due to supply structure. Buyers prioritise size, beauty, and ethical sourcing rather than speculative resale value.
