Are lab-grown diamonds real diamonds?

Yes. They are crystallised carbon with the optical and physical characteristics associated with diamond. They are not cubic zirconia or moissanite. Specialist equipment can distinguish their growth origin, and a reputable grading report identifies the stone as laboratory grown.

Why do they cost less?

Natural diamonds are geologically scarce and expensive to recover. Lab-grown production can be repeated and scaled, so supply is less constrained. That generally allows a customer to choose a larger stone or higher colour and clarity within the same budget.

What about future value?

Buy a lab-grown diamond for the ring you want to wear, not as an investment. Prices have changed substantially as production has expanded, and resale values can be limited. Natural diamonds also should not be presented as guaranteed investments, but their supply dynamics are different.

CVD and HPHT

Both are legitimate growth methods. The method alone does not tell you whether a diamond is beautiful. Each stone should still be assessed for colour nuance, transparency, strain, inclusions, cut quality and post-growth treatment disclosures.

Do high grades guarantee a good stone?

No. A D-colour, VVS diamond can still have an unattractive outline, poor proportions, visible bow-tie or weak light return. It may also be needlessly expensive for what the eye can appreciate. The report narrows the field; visual assessment makes the final decision.

LADFOX approach: we generally prefer IGI reports for lab-grown diamonds, then review the stone itself, its proportions and imagery before recommending it.

Choosing a sensible specification

The right specification depends on shape, setting and budget. Many customers can prioritise cut, outline and dimensions over microscopic clarity differences. With elongated stones, ratio and bow-tie control matter. With emerald cuts, transparency and facet pattern deserve particular attention.

Lab-grown coloured diamonds and gemstones

Laboratory-created colour offers another route to a distinctive design. Coloured lab-grown diamonds, sapphires and emeralds can achieve a particular look without the rarity premium of a comparable natural stone. Durability and care still vary by material, so the choice should suit everyday wear.
