About Lab-Grown Diamonds
Identical to a mined diamond in every meaningful way. An Isla Bella diamond possesses the same chemical composition, fire, and brilliance as a mined stone — simply created with modern precision rather than extracted from the earth.
No. Even experienced gemologists cannot distinguish between them without specialist testing. Every Isla Bella diamond is IGI-certified, confirming its authenticity and quality.
Lab-grown diamonds allow you to choose a larger, higher-quality stone for your budget — without compromising on beauty or brilliance. More of your investment goes into the diamond itself.
IGI (International Gemological Institute) is one of the world's leading independent diamond grading laboratories. Every Isla Bella diamond comes with a certificate detailing its cut, colour, clarity, and carat weight — full transparency in every purchase.
Quality & Craftsmanship
Every Isla Bella diamond meets our premium standard — D–F colour for a bright white appearance, VVS clarity for exceptional purity, and Excellent cut for maximum brilliance. We do not offer lower-grade stones or misleading entry prices.
Yes. Every ring is independently hallmarked by the Edinburgh Assay Office, confirming the metal purity meets official British standards.
