Fancy Green Lab Grown Diamonds
Green is among the rarest fancy colors in both natural and lab-grown diamonds, and the science behind it is genuinely distinct from every Another fancy color. Natural green forms when a diamond sits near radioactive minerals in the earth for millions of years — radiation displaces carbon atoms in the crystal lattice, creating defects (known as GR1 centers) that produce the green hue. Lab-grown green replicates this exact same physical mechanism deliberately: controlled irradiation applied after the stone is grown, followed by annealing, creates the identical lattice defects in a fraction of the time.
This is worth being direct about, the same way we are with our fancy pink stock: the color is treatment-based, not as-grown. But because the underlying change is a permanent alteration of the crystal lattice itself — not a surface coating — the color is stable and won’t fade under normal wear, cleaning, or light exposure. Every green stone we sell states its treatment status clearly on its IGI certificate.
OCS Diamond sources fancy green on both limited ready-stock and custom-order request from our Surat facility. Given the category’s naturally lower volume industry-wide, we’re direct about availability: this is not a deep-inventory category the way yellow or white stock is, and buyers should expect to inquire about current specific availability rather than assume broad on-hand stock.

How Green Color Is Created
Green is scientifically distinct from every other fancy color — it’s the only one caused by radiation exposure rather than trace elements or lattice distortion. Natural green forms when a diamond sits near radioactive minerals for millions of years; lab-grown green replicates this precisely through controlled irradiation followed by annealing, applied after CVD or HPHT growth. The resulting atomic-level defects (GR1 centers) are identical to what forms naturally — the lab process is simply faster and controlled.
Sourcing Note
Because fancy green is a lower-volume category, current availability can vary by carat weight, clarity, shape, and color intensity. We recommend contacting our team to confirm the availability of a specific stone or specification before placing an order.
If the required green diamond is not currently in stock, custom orders follow our standard 10-business-day manufacturing timeline.
Where Fancy Green Diamonds Are Most Commonly Used
Given limited stock depth, green is almost exclusively a signature center-stone color — used in one-of-a-kind pieces or small curated collections rather than volume retail lines. Designers typically pair it with white diamond accents or a simple solitaire setting to let the rare color carry the piece, rather than competing with other colored stones in the same design.
Frequently Asked Questions






Treated — via controlled irradiation and annealing, the same physical mechanism (though deliberately applied) that creates green color in rare natural diamonds. This is stated clearly on the IGI certificate.
No. The treatment creates a permanent change within the diamond’s crystal lattice rather than a surface coating. The color is stable under normal wear, cleaning, and light exposure.
Producing consistent, well-saturated green requires precise irradiation control, and industry-wide demand and production volume for green is lower than for yellow or pink. We’re upfront that this means less on-hand stock and more reliance on custom orders.
Our standard custom manufacturing timeline is 10 business days, subject to confirmation of the requested specifications.
Yes — custom cut requests can be combined with fancy color orders; contact our team to confirm feasibility and timeline for your specific combination.
