Green diamonds are among the most captivating stones in the world of fine jewellery — quietly rare, unmistakably distinctive, and carrying a depth of colour that ranges from the softest whisper of mint to a rich, saturated forest tone. Whether you are drawn to them for their rarity, their symbolism, or simply their beauty, you may already be asking yourself the same question many of our visitors arrive with: where can I buy green diamonds online?
The answer, for those who want genuine choice, certified quality, and the support of a specialist team, begins with our online diamond search.

Understanding IGI Colour Descriptions for Green Diamonds
When you browse fancy coloured diamonds — including green — you will encounter grading language that may be unfamiliar. The International Gemological Institute (IGI) uses a standardised system to describe both the intensity and the hue of a coloured diamond's colour. Understanding these terms will help you choose with confidence.
Colour Intensity Grades
IGI grades the depth of colour in a fancy coloured diamond using the following scale, from lightest to most saturated:
| Intensity Grade | What It Means |
|---|---|
| Faint | A very subtle hint of colour, barely perceptible |
| Very Light | Colour is visible but remains delicate and understated |
| Light | A gentle, clearly present colour with moderate saturation |
| Fancy Light | The first grade in the 'Fancy' range — colour is evident and appealing |
| Fancy | A well-balanced, moderately saturated colour |
| Fancy Intense | Rich, vivid colour with strong saturation |
| Fancy Vivid | The most saturated and desirable grade — exceptionally rare in natural stones |
| Fancy Deep | Deep, dark tone with strong colour presence |
| Fancy Dark | A very dark tone; intense but with reduced brightness |
For most buyers, Fancy Light through to Fancy Intense represents the sweet spot — stones that display beautiful, unmistakable green colour at a range of price points.
Hue Modifiers in Green Diamonds
Pure green diamonds — those graded simply as "Fancy Green" — exist, but many stones carry secondary hues that modify the primary colour. These modifiers are noted in the IGI grading report and affect both the appearance and the value of the stone.
| Modifier Description | What It Looks Like |
|---|---|
| Yellowish Green | Warm, lime-toned green with a golden undertone |
| Yellow Green | An equal blend of yellow and green — bright and lively |
| Bluish Green | A cool, teal-inflected green with depth |
| Blue Green | A near-equal mix of blue and green — rare and striking |
| Greyish Green | A muted, sophisticated green with a steely undertone |
| Grey Green | Desaturated green with a pronounced grey modifier |
| Brownish Green | Earthy, olive-toned green |
| Green | Pure green with no significant secondary hue — the rarest descriptor |
When reading a certificate, the last colour named is always the dominant hue. So a stone described as "Fancy Intense Yellowish Green" is primarily green, with yellow as a secondary influence. This convention is consistent across IGI grading.
Natural vs Lab-Grown Green Diamonds — Rarity, Price, and Value
Natural Fancy Green Diamonds
Natural green diamonds are extraordinarily rare. Their colour is formed when the crystal structure of the diamond is exposed to natural radiation over millions — sometimes billions — of years beneath the earth's surface. This process is entirely unpredictable, which is why truly fine natural green diamonds command prices that can rival or exceed many other fancy colours, including pink and blue.
A natural fancy green diamond of one carat and above, with strong saturation and a clean hue, is a serious collector's stone. Stones graded Fancy Intense or Fancy Vivid are among the most valuable diamonds per carat weight in the world.
Lab-Grown Green Diamonds — Exceptional Value in Larger Sizes
Lab-grown green diamonds offer a remarkable alternative for buyers who want the visual beauty of a green diamond without the price premium associated with natural rarity. Grown in controlled laboratory conditions using the same carbon structure as natural diamonds, lab-grown stones are optically, chemically, and physically identical to their mined counterparts.
Where the difference becomes truly significant is in larger carat weights. A natural fancy green diamond of two carats or more would represent an investment of many tens of thousands of pounds. A lab-grown equivalent — with comparable colour, clarity, and cut — can be acquired for a fraction of that figure.
This makes lab-grown green diamonds particularly well suited to bespoke jewellery commissions where size and visual impact are part of the brief. A large, vivid green centre stone that would be financially beyond reach in natural form becomes an entirely achievable ambition in lab-grown.
You can explore both natural and lab-grown green diamonds directly through our diamond search, where each listing clearly identifies the stone's origin alongside its IGI certification details.

What Happens Next? Turning Your Green Diamond Into a Ring
Purchasing the diamond is only the beginning. The question most buyers ask at this point is a natural one: what do I do with it?
This is where Serendipity Diamonds comes into its own.
Bespoke Ring Design — Built Around Your Stone
Every green diamond is individual. Its shape, dimensions, and colour character all influence what will suit it best as a mount. Our team works with clients to design bespoke ring settings built entirely around the chosen stone and the client's vision — from a simple, refined solitaire that lets the colour speak for itself, to a more elaborate halo or side-stone design that frames and elevates the green.
Bespoke commissions are created to your exact specification: choice of metal — platinum, white gold, yellow gold, or rose gold — finger profile, band width, prong style, and finish. The result is a ring that exists nowhere else.

Choosing from Our Existing Ring Designs
If your diamond is suitably sized, it can also be set into any ring design from this website or from the Serendipity Diamonds engagement ring collection. Many of our ring mounts are available in a range of precious metals and can be adapted to accommodate different stone shapes and carat weights.
This approach combines the joy of choosing a distinctive coloured stone with the confidence of a tried and tested design — a beautiful middle ground between fully bespoke and off-the-shelf.
Whether you are drawn to a classic four-claw solitaire in platinum, a vintage-inspired design in warm yellow gold, or something more sculptural and contemporary, our team will advise on which mounts are best suited to your chosen green diamond and how the pairing will look in practice.
