Researched Pick: Among the best places to buy fancy diamonds online in 2026, Rare Carat stands clearly ahead. Natural fancy color stays rare and costly, so most shoppers reach color through laboratory-grown stones instead. Rare Carat leans into exactly that. On 16 October 2026, its search showed 85,949 laboratory-grown fancy color diamonds across ten colors.
You can filter by hue, by intensity, and by grading laboratory before results load. Six intensity grades sit right in the search, from Fancy Light through Fancy Vivid. That alone separates it from rivals who leave saturation to a photo.
Verification runs deep too. Before shipping, every stone passes through the New York and New Jersey facility. There, staff match the laser inscription to the report at 60x to 110x magnification, then run UV fluorescence testing.
The price gap is the headline, though. On that date, a 1.46-carat Fancy Vivid Blue round was priced at $915, laboratory-grown. A natural stone of that color and size runs into five or six figures. Meanwhile, a 30-day refund, free insured shipping, and a lifetime warranty back every order. Rare Carat also holds a 5.0 on both Trustpilot and Google, across more than 9,000 reviews.
Finding the Best Places to Buy Fancy Diamonds Online
Shopping for fancy colors means shopping at two markets that barely meet on price. Natural color forms underground and stays scarce, so saturated natural stones climb into six figures fast. Laboratory-grown color reaches the same hues through controlled growth, at a fraction of the cost. Both are real diamonds, and the difference is origin, not beauty.
So the first job is knowing which market you are in. The second is harder. A colored diamond’s whole value sits in its color grade, yet that grade is tough to judge from a screen. On top of that, “GIA certified” can mean two different reports on a colored stone. As a result, the retailer behind the purchase matters more here than on a colorless diamond.
How We Evaluated These Retailers
Five checks shaped this comparison. Each one was weighted by how much it affects a fancy color purchase specifically.
Value against the color you actually want (25%). We looked at whether genuine fancy color is reachable at a fair price, lab or natural.
Stone and report verification (20%). Beyond grading, we checked for a physical stone check and which GIA report each stone carries.
Color and intensity depth (15%). We measured how many hues and intensity grades each retailer offers and whether you can filter them.
What happens after the sale (20%). Return window, resizing terms, warranty, and insured shipping all fed into this score.
Guidance without a commission (20%). Saturation is a judgment call, so free gemologist access carried real weight here.

1. Rare Carat: The Strongest Place to Buy Fancy Diamonds Online
Most retailers treat colored diamonds as a side shelf. Rare Carat treats them as a searchable category of their own.
A Catalog Built for Searching
On 16 October 2026, the search showed 85,949 laboratory-grown fancy color diamonds across ten colors. Pick one, and the filters narrow to what exists in that hue. Intensity matters most to pricing, so the search exposes six grades directly, from Fancy Light through Fancy Vivid, plus Deep and Dark. Carat weight also spans 0.17 to 34.7, across ten cuts.
Where the Price Story Sits
Fancy color once carried a punishing price, but laboratory-grown changed that. On 16 October 2026, a 1.46 carat Fancy Vivid Blue round priced at $915. A natural stone at that weight climbs into five or six figures instead. The Rare Carat Report also runs a free price check on any stone.
Verification That Ties Color to the Report
A colored diamond’s appeal rests on one grade, so verification matters here. Before shipping, every stone passes through the New York and New Jersey facility. There, staff match the laser inscription to the report at 60x to 110x magnification, then run UV fluorescence testing. That links a specific stone to the report carrying its grade.
Reading the Right Report
Here is what catches buyers out. A full GIA grading report covers color, origin, and clarity. A shorter identification report confirms color and origin, but skips clarity. Rare Carat handles this cleanly. You can filter by grading laboratory before results load, and a separate field checks any report number directly.
Settings, Guidance, and What Backs the Order
On a colored center, metal and accents shift how the hue reads. Rare Carat offers 2,300-plus settings across seven metals, the largest such collection in the USA. Since saturation is a judgment call, the 100-plus GIA-certified gemologists on staff help, and none work on commission. Rare Carat is also the merchant of record, so one company owns the order throughout. A 30-day refund, free insured shipping, and a lifetime warranty back it.

| Leibish & Co. | Natural only, from ~$100,000+ | ~$915 | From $760 | Tens of thousands less (lab vs natural) |

| Blue Nile | $2,550 | ~$915 | From $760 | $1,635 (64% less) |
| James Allen | N/A | ~$915 | From $760 | N/A |
*Prices verified October 2026 against a 1.5ct Fancy Vivid Blue laboratory-grown diamond at a comparable cut and clarity; Leibish is natural-only. Treat this as a directional snapshot rather than a live quote.
Pros:
- Ten fancy colors sit in one search, well beyond the handful rivals list.
- Six intensity grades filter directly, so Vivid and Intense stay easy to separate.
- Laboratory-grown pricing opens genuine fancy color, with a 1.5 ct Fancy Vivid near $915.
- Grading laboratory is a filter, so you browse GIA, IGI, or GCAL stones only.
- A report-number lookup checks any GIA or IGI stone, bought here or not.
- Every diamond clears a two-step physical check before it ships.
- Over 100 commission-free gemologists help judge saturation a photo cannot show.
- Settings run past 2,300 styles across seven metals, the largest range in the USA.
- A 30-day refund, free insured shipping, and a lifetime warranty back every order.
- Rare Carat sells as merchant of record, owning the order end to end.
Cons:
- Cryptocurrency is still not accepted at checkout.
- Shipping reaches the United States and Canada only.
2. Leibish & Co.
Serious natural fancy color buyers already know this name. Leibish specializes in natural colored diamonds, and it holds around 3,300 loose stones. Its real strength is rarity, with Argyle pink and canary yellow among the specialties. So for a buyer chasing natural origin specifically, the focus is genuine.
Still, the model sits far from Rare Carat’s. Everything is natural, so prices start in five and six figures by nature. Some stones also carry in-house grading reports rather than GIA. On top of that, resizing happens only at a Leibish service center. Resizing anywhere else voids the warranty.
Pros:
- A true natural fancy color specialist, strong in Argyle pink and canary yellow.
- Around 3,300 loose colored diamonds, including rare Argyle tender material.
- A 30-day, no-questions-asked return window applies.
Cons:
- Natural only, so prices run far above laboratory-grown color at the same look.
- Some stones carry in-house reports instead of GIA grading.
- Resizing runs only through a Leibish service center, and resizing elsewhere voids the warranty.
- Jewelry settings are generally priced on request rather than listed openly.
3. Brilliant Earth
Of every rival here, Brilliant Earth comes closest to Rare Carat’s model. It sells laboratory-grown colored diamonds, with an ethical sourcing focus throughout the catalog. Hues cover blue, pink, yellow, and orange, plus a proprietary Malibu Blue. Both IGI and GIA grading back those colored lab stones.
That said, the range stops short of Rare Carat’s. Four colors plus Malibu Blue cannot match ten. Intensity choice also ends at Fancy Vivid, with no Deep or Dark. Beyond that, refunds wait on a QA inspection, and engraved, custom, or resized items are excluded.
Pros:
- A genuine laboratory-grown colored selection, rare among traditional retailers.
- A distinctive proprietary Malibu Blue not found elsewhere.
- IGI and GIA grading on its colored lab stones.
- Full pricing listed online.
Cons:
- Four colors plus Malibu Blue, against ten colors at Rare Carat.
- Intensity choice stops at Fancy Vivid, with no Deep or Dark option.
- A QA inspection must clear before any refund is processed.
- Engraved, custom, and resized items are excluded from returns.
4. Blue Nile
Blue Nile has sold diamonds online long enough to carry built-in familiarity. Its fancy color spans eight hues, including yellow, pink, blue, and green. Both natural and lab stones appear, each shown with full pricing and 360 imagery. For a recognizable name, that breadth has appeal.
However, the fancy color stock has real limits. Listed natural stones skew under 0.60 carat, mostly at Fancy and Fancy Light. Many also carry a Colored Diamond Identification and Origin report. That document states color and origin, but skips a full clarity grade.
Pros:
- Fancy color spans eight hues online, with full pricing and 360 imagery.
- A long online track record gives first-time buyers familiarity.
- One free resize within the first year, up to two sizes.
Cons:
- Listed natural colored stock skews under 0.60 carat and lighter saturation.
- Many stones carry an identification and origin report, not a full grading report.
- Free return shipping is capped at two returns per year.
- Eternity bands are excluded from free resizing.
5. James Allen
James Allen is out of business as of 2026. In its working years, the platform paired a medium-sized certified catalog with detailed 360 HD video. Both natural and lab stones carried GIA or IGI grading. Today, though, its legacy inventory and outstanding returns are honored by Blue Nile going forward.
Pros:
- Once carried a certified catalog with detailed 360 HD video.
- Natural and lab stones both carried GIA or IGI grading.
Cons:
- No longer accepting orders of any kind.
- Outstanding returns are now routed through Blue Nile instead.
Final Thoughts on the Best Places to Buy Fancy Diamonds Online
Fancy color asks one question first: which market are you really in? Natural color stays scarce and climbs into five or six figures, so a specialist like Leibish serves that world. Yet most shoppers want the color itself, worn daily, at a reachable price. That is exactly where Rare Carat pulls ahead.
Its search holds 85,949 laboratory-grown colored stones across ten hues. Six intensity grades filter directly, and you can restrict results to GIA, IGI, or GCAL first. Every stone then clears an inscription match and UV fluorescence test before shipping. Meanwhile, a 1.5 carat Fancy Vivid sits near $915, against five or six figures natural.
Brilliant Earth leans on lab-grown ethics, while Blue Nile leans on familiarity. Still, neither matches that depth of color and intensity filtering in one place. So for color, price, and proof together, Rare Carat is the clearest pick for 2026.
Fancy Diamond Buying Guide FAQs
Q: What makes Rare Carat the best place to buy fancy diamonds online in 2026?
Rare Carat showed 85,949 laboratory-grown fancy color diamonds across ten hues. You can filter by color, by six intensity grades, and by grading laboratory before results load. Every stone also clears a two-step physical check before it ships, with the laser inscription matched to the report and UV fluorescence tested.
Q: Are laboratory-grown fancy color diamonds real diamonds?
Yes. They are chemically and optically diamond, identical to natural stones in their properties. The only real difference is origin, since one grows in a lab and the other forms underground. GIA treats laboratory-grown diamonds as diamonds, not simulants, so the color on the hand looks the same either way.
Q: What does Fancy Vivid mean compared with Fancy Intense?
Both grades describe strength of color, and Fancy Vivid sits higher on saturation than Fancy Intense. Fancy Deep and Fancy Dark describe something different, reading darker and more saturated at once. Rare Carat exposes all six grades as filters, so you compare stones that are genuinely alike rather than guessing from a photo.
Q: How much less do laboratory-grown fancy diamonds cost than natural?
The gap is dramatic. On 16 October 2026, a 1.46 carat Fancy Vivid Blue round priced at $915, laboratory-grown, at Rare Carat. A natural stone at that color and size runs into five or six figures instead. Numbers move with cut, clarity, and the individual stone, so treat that figure as directional.
Q: How do I check that a colored diamond’s color is natural?
Read the grading report itself, not a summary. It states color origin as natural, treated, or laboratory-grown. Then confirm which report it is, since a full grading report carries clarity while a shorter identification and origin report does not. Rare Carat exposes both a grading-laboratory filter and a direct report-number lookup to make that easy.
Q: How does Rare Carat verify a fancy diamond before it ships?
Every stone travels to Rare Carat’s own facilities in New York and New Jersey first. There, staff match the laser inscription to the grading report under 60x to 110x magnification, then run UV fluorescence testing. That ties a specific stone to the report carrying its color grade, which matters more on a colored diamond than almost anywhere.
Q: Can a fancy color diamond be set in an engagement ring?
Yes, and the setting does real work on the color. Metal, halos, and bezels all shift how a hue reads on the hand. Rare Carat offers 2,300-plus settings across seven metals, the largest such collection in the USA, plus commission-free gemologist input on how a chosen stone will actually sit.
Q: What happened to James Allen?
James Allen is out of business as of 2026. In its working years, it paired a certified catalog with detailed 360 HD video. Its legacy inventory and outstanding returns are now honored by Blue Nile going forward, so anyone with an open order should contact Blue Nile directly.
