Lab-grown coloured diamonds are a fast-growing request category

Lab-grown pink and blue diamonds, produced with post-growth treatment, are a small but fast-growing request category, offering fancy colour at a fraction of natural fancy colour pricing.

• Most lab-grown fancy colour stones reach their final colour through irradiation and annealing after growth, a treatment that must be disclosed on the grading report.
• Pricing sits well below natural fancy colour stones of comparable colour and saturation, which is the main draw for buyers choosing lab-grown here.
• Buyers should confirm treatment disclosure explicitly, distinct from the broader push on post-growth treatment disclosure for colourless CVD stones.

Every lab-grown fancy colour stone we sell states its treatment history in full on the report. Contact us to see current fancy colour lab-grown stock.
