Astrea’s Promise

We only source our lab diamonds from high-end manufacturing partners, allowing you to understand every step of your diamond’s journey.

Focusing primarily on premium colour grades (D, E and F), our diamonds are of the highest quality, selected with a minimum clarity of VS1 and in an Ideal or Excellent cut.

All our diamonds are Type II and Type IIa lab diamonds – a quality rating that only 1-2% of the world’s diamonds achieve. Those above 0.5 carats will be GIA or IGI certified, and laser inscribed. Our gemologists also provide certification on all jewellery pieces, proving our commitment to authenticity and transparency.

Additionally, every diamond is also inspected by our highly-experienced team of certified experts and graders, skilled in assessing the highest quality and value of diamonds.

All bespoke enquiries come with a CAD drawing for approval before purchase, giving you total peace of mind.

We deliver exclusivity and excellence.
