Lab-grown diamonds have the same fire, brilliance, and durability as mined diamonds — because they are diamonds. The only difference is where they were formed. At OROSERGIO, we set lab-grown diamonds into custom jewellery with the same craftsmanship and care as any natural stone.
What Are Lab-Grown Diamonds?
Lab-grown diamonds are real diamonds produced in certified facilities using advanced technology that replicates the conditions under which natural diamonds form. They have the same crystal structure, hardness, and optical properties as mined diamonds — because they are the same material: pure crystallized carbon.
Two methods are used to grow diamonds. High Pressure High Temperature (HPHT) places a diamond seed in a carbon-rich environment under extreme pressure and heat — mimicking the Earth's mantle. Chemical Vapor Deposition (CVD) grows diamond crystal layer by layer from a carbon gas in a vacuum chamber. Both produce stones that are indistinguishable from mined diamonds.
At OROSERGIO, every lab-grown diamond is hand-selected by Sergio for cut quality, colour, and clarity before being set into your custom piece. Center diamonds of meaningful size come with independent IGI certification.

Why Choose Lab-Grown Diamonds
Lower Stone Cost
Lab-grown diamonds cost significantly less than comparable mined stones — allowing you to go bigger on carat size or invest in a more intricate setting.
Mining-Free Origin
Lab-grown diamonds avoid mined-diamond sourcing concerns by origin. Sergio reviews lab-origin documentation where applicable before a stone is approved.
Independently Certified
Center diamonds of meaningful size are commonly independently graded by IGI. Smaller accent stones are not individually certified.
Identical Beauty
Same fire, same brilliance, same durability. Lab-grown diamonds are optically and physically indistinguishable from mined diamonds.
Antique Cuts in Lab-Grown Diamonds
Antique cuts — old mine, old European, and rose cut — give a diamond a soft, candlelit glow and a vintage romance that has become one of the most sought-after looks in engagement rings. Because an antique cut is a faceting style rather than an origin, it can be applied to a lab-grown diamond just as easily as a natural one.
This is where lab-grown stones make particular sense. Genuine antique mined diamonds are rare, sourced one at a time, and priced accordingly. A lab-grown diamond cut in an antique style gives you the same hand-cut character — the tall crown, the open culet, the warm glow — at a usually lower price, and lets you choose the exact carat weight and shape you want rather than waiting for the right estate stone to surface.
If you love the vintage look but want it new, larger, or more affordable, Sergio can source a lab-grown stone cut in an old mine, old European, or rose-cut style and design a setting around it. For the romance of a genuinely old stone instead, explore our natural and antique mined diamonds.
