Trust in Traceability
Lab grown diamonds are crafted in high tech laboratories and can be traced right back to their origin so that you can be 100%confident your diamonds are conflict free and ethically produced. At Astrea, we invite you to explore a world where elegance meets ethics, where luxury can be enjoyed every day, and where your choice reflects a commitment to a brighter, sustainable future for our planet and our children.
The Certificate
We guarantee that all our diamonds over 0.25cts are GIA or IGI certified, providing clarity and authenticity. We can also source smaller certified diamonds upon request. All our stones (regardless of size) are individually inspected by our highly-trained specialists to ensure we only procure the very best diamonds on the market. We will also provide an Astrea certificate on all pieces so that your purchase is quality assured and verified.
Our resident team of diamond experts check the details of the certificates against the stones, and also assess the following characteristics of all our diamonds.
The Sparkle
A diamond’s true sparkle is an elusive magic that goes beyond the certificate. Only a physical inspection by our experts can reveal the nuances in Cut, Polish, and Symmetry that make some diamonds shine brighter than others.
Inclusions
Our gemologist experts meticulously examine each diamond, ensuring no imperfections or undisclosed inclusions compromise its beauty. We guarantee you will receive a flawless gem that stands the test of scrutiny.
Girdle
While the certificate details the girdle, judging the quality of a fancy-shaped diamond requires more than just paperwork. Physical inspections unveil the true size and perfection of a diamond’s girdle – a factor crucial to its overall allure. Your perfect diamond deserves a hands-on assessment.
Colour Shade
Lab-grown diamonds, if not grown perfectly, might reveal subtle hues unseen by machines. Our experts, however, catch these nuances, ensuring the true colour of your diamond shines through, identifying and preserving the authentic essence that impacts your diamond’s value.
Fancy-Shaped Diamonds
Certificates for fancy-shaped diamonds lack cut grades, leaving a crucial aspect uncharted.Our experts will assess the cut quality, especially for fancy diamonds, ensuring every facet meets the highest standards of brilliance.
Ratio of the Diamond
The industry’s set standards for each shape, like the ratio for an oval, can impact a diamond’s appearance. A perfect ratio ensures you get the visual impact you desire. Our specialists will check this vital element physically, so you never pay for a 2-carat diamond that looks like 1.50 carats.
We believe that true value and quality goes beyond the certificate. Our expert gemologists physically inspect each diamond, ensuring that your chosen stones are only of the highest quality and sparkle.
