What is IGI certification?

The International Gemological Institute (IGI) is a leading independent laboratory that evaluates and grades diamonds. An IGI certificate guarantees the authenticity, quality, and specific characteristics (cut, colour, clarity, and carat) of our lab-grown diamonds, giving you complete confidence in your purchase.

Why choose lab-grown diamonds?

Lab-grown diamonds are physically, chemically, and optically identical to natural diamonds. They offer exceptional value and beauty while being created in highly controlled environments, making them a brilliant choice for modern fine jewellery.

Do you offer a warranty?

Yes. We stand behind our craftsmanship with a complimentary lifetime warranty on all pieces.

How long does delivery take?

• Ready-to-ship pieces are dispatched within 24 hours • Bespoke creations are typically delivered within 3–4 weeks

Do you offer a warranty?

Yes. All Masaat London pieces are covered by a complimentary lifetime warranty.
