Yellow laboratory-grown diamonds
Yellow lab-grown diamonds, wholesale
Yellow laboratory-grown diamonds for designers and brands, sorted for consistent colour and supplied direct from the grower.
Where the colour comes from
Yellow comes from nitrogen atoms spread singly through the crystal, which absorb blue light. HPHT growth readily takes up nitrogen, so strong canary yellows can be grown directly. These diamonds are Type Ib.
Usual method: HPHT, usually as-grown.
What to know when buying
- Permanent colour. Nitrogen colour is part of the crystal.
- Range. From light lemon to intense canary; specify the intensity you sell.
- Calibrated goods. Yellow suits calibrated melee and accent parcels as well as centre stones.

Questions buyers ask
Are yellow lab-grown diamonds treated?
Usually not. Strong yellows are typically grown directly by HPHT, with nitrogen giving the colour. We disclose any treatment.
Do you disclose post-growth treatment?
Yes. Some CVD diamonds are treated after growth to improve colour. We tell you which stones are as-grown and which are treated, and independent grading reports note it.
Do you supply fancy colours?
Yes, we work in fancy colours including pink, blue and yellow. Ask us what is available now and what we can grow to order.
