Large Yellow Lab-Grown Diamonds: Canary Tones from 5 to 20+ Carats

Ask ten trade buyers for a "canary yellow," and you will get ten different stones. The word is a trade nickname for a strong, clean yellow, not a grade on a laboratory report. The report says Fancy Intense Yellow or Fancy Vivid Yellow, and that wording decides colour, price, and how the stone will look in a setting. This guide explains how to read it, which shapes and sizes exist from 5 ct to 20+ ct, how to set big yellow stones, and how to brief a supplier so the quote you get back is the stone you wanted. Liora Diamond supplies laboratory-grown yellow stones to trade buyers, and the examples below come from Liora Diamonds' own range.

Key Takeaways

• "Canary" is a retail word, not a report grade. GIA says yellow diamonds are "often called canary diamonds by retailers" and grades them by hue, tone, and saturation across nine categories, with most jewellery yellows falling in Fancy Light, Fancy, Fancy Intense, or Fancy Vivid diamonds.
• Size is available, but check the exact stone. Liora Diamonds' yellow range includes IGI-graded stones such as a 21.00 ct Fancy Intense Yellow heart and a 20.09 ct Fancy Intense Yellow oval, plus Fancy Vivid Yellow cushions and pears above 7 ct.
• Purity of hue matters as much as intensity. GIA explains that pure yellow diamonds are rarer and more desirable than those with brownish or greenish modifiers, so read the full grade line, including words like "Grayish" or "Orangey".
• Colour origin is disclosed. GIA notes that yellow in both HPHT and CVD stones is produced by introducing nitrogen during growth, and Liora says lab-grown fancy colours are usually created or intensified after growth, recorded in the report and stated on the invoice.
• Demand is moving through trade hubs. DMCC reported that the UAE traded 76.9 million carats of lab-grown material in 2025, up 91.5%, worth US$1.3 billion (this includes industrial material), and Liora Diamonds' country-specific dealings in wholesale lab-grown diamonds for the USA, UAE, Japan and Australia all list fancy yellow among the hues buyers ask for.

Quick Answer

• What is a canary yellow lab-grown diamond? A canary yellow lab-grown diamond is a trade nickname for a saturated yellow stone, usually graded Fancy Intense or Fancy Vivid Yellow on its report, not an official grade.
• Where can I buy large yellow lab-grown diamonds wholesale? Liora Diamond supplies loose yellow lab-grown diamonds wholesale to trade buyers, including IGI-graded stones from 5 ct to 20+ ct, with reports shared before invoicing.
• How do I choose between Fancy Intense and Fancy Vivid yellow? Compare both grades in daylight video of the exact stone, then decide whether your setting needs the deeper saturation of Vivid or the lighter colour of Intense.

Yellow vs "Canary": Trade Words and Report Words

Search for yellow diamonds, and you will meet "canary yellow", "fancy yellow", "intense yellow", "vivid yellow" and, for lab-created stones, "yellow lab grown diamond" and "yellow lab created diamond". They are not interchangeable. Only some of them appear on a report.

GIA explains that its fancy colour system is based on the presence of colour and describes colour by hue, tone and saturation. The grade word, such as Fancy Intense, describes the effect of both tone and saturation. The grade line on the report is the one to quote on your RFQ. For background on reports, see why diamond certification matters for B2B buyers and our guide to IGI-certified lab-grown diamonds.

Intensity Choices for Yellow Colored Diamonds

Liora Diamonds' fancy colour page describes the scale as Fancy Light, Fancy, Fancy Intense, Fancy Vivid, and Fancy Deep, and says intensity sets the price. For yellow, that scale decides three practical things.

1. Fancy Light Yellow is a soft, pale yellow. It is easier to wear across a wide customer base and suits designers who want yellow to read as a tint rather than a statement. Liora Diamonds' range includes a 12.07 ct Portuguese-cut Fancy Light Yellow and several Fancy Light Yellow rounds and pears around 5 ct.
2. Fancy Intense Yellow is the working grade for large centre stones. The colour is clearly yellow at a glance, which is why it is the grade buyers ask for most often on large stones. Liora Diamonds' 21.00 ct heart and 20.09 ct oval are both Fancy Intense Yellow.
3. Fancy Vivid Yellow is the stronger, more saturated option. It suits statement pieces and brands that want an unmistakable yellow. Liora Diamonds' range includes a 10.03 ct Fancy Vivid Yellow cushion and a 7.68 ct Fancy Vivid Yellow cushion.

Colour does not read the same on a screen as in the hand. It's advisable to ask for a video under daylight, and that is the right habit before you approve any stone. If you are deciding between two grades, our guide to fancy colour lab-grown diamond supplier sourcing and the wholesale fancy coloured lab-grown diamonds guide explain how grades are priced and described.

Which Big Yellow Shapes are Available at Liora Diamond?

Liora Diamonds' yellow-colored diamond range covers the common fancy shapes: pear, oval, cushion, radiant, heart, round and emerald, plus Portuguese cuts and, in smaller sizes, baguette, Cadillac, shield, kite and trilliant. The table shows representative IGI-graded stones from 5 ct upward. Check current availability before you plan around any one of them.

Prices are quoted on request through WhatsApp, so ask the trade desk for the stone you shortlist. Browse the yellow lab-grown diamonds from 5 ct or the full yellow lab-grown diamond selection, then filter by pear or oval if your design needs an elongated outline. Our Big Diamonds page covers stones from 3 ct upward, with an IGI report as standard and GIA grading available on request.

How the size steps differ

A 5 ct yellow is a ring stone. A 10 ct yellow is a large ring or pendant stone. A 20 ct yellow is high jewellery: the setting, the metal, and the insurance conversation all change. If you are working up the size ladder, read our 5 carat, 10 carat, 20 carat, and 30 carat wholesale guides first, and the large pink lab-grown diamonds guide for the sister colour that dominates the large-stone range.

Setting Yellow: Metal Colour Choices

Metal changes how a yellow stone reads, and that is a design choice, not a grading issue. These are common approaches, offered as practice rather than rules.

• White metal (platinum or white gold) separates the stone from its mount, so the yellow looks cooler and cleaner. Many designers choose it for Fancy Intense and Fancy Vivid stones where they want the colour to stand alone.
• Yellow gold blends with the stone and gives a warmer, monochrome look. It tends to suit lighter grades, where the metal supports the colour instead of overpowering it.
• Rose gold adds a warmer contrast and works well when the stone has an orangey modifier.
• White diamond accents around a yellow centre sharpen the colour contrast. Ask for the accents to be graded against each other so the halo does not clash with the centre.

Colour in the hand also depends on light, so test the finished piece in daylight and shop lighting before you approve a production run. If you make jewellery, our guide to choosing a lab-grown diamond supplier for jewelry manufacturers covers specifications for setters, and our B2B jewelry page covers finished work.

Pairs, Suites and Parcels in Yellow Diamonds

Our Big Diamonds page explains that pairs are matched for colour, clarity, measurements, and make, starting at 2 ct each. For earrings in yellow, the match matters more than usual because two stones of the same grade can still look different side by side. Ask for both reports and a side-by-side video in the same light.

For suites, with a centre stone, side stones and a halo, Liora Diamonds' fancy colour page describes small stones sorted by hue and intensity so the whole piece reads as one colour. It says parcels are calibrated by size with tolerances agreed in advance, a photo of the whole parcel is sent before shipping, and repeat orders are matched to the previous parcel. Liora Diamonds' UAE page lists yellow as available as singles, pairs, or matched parcels. Put the tolerance and colour range on the order, not just in an email.

Is the Colour Natural or Created After Growth?

Buyers and their customers ask this, so have the answer ready. GIA explains that in both HPHT and CVD growth, nitrogen is introduced to produce a yellow hue. Liora Diamonds' fancy colour page says lab-grown fancy colours are usually created or intensified after growth, that the grading report records this, and that the invoice discloses it. It also says the colour is stable in normal wear. Keep the report with the stone, and write "laboratory-grown" on every onward invoice and listing. Our CVD diamond supplier guide and HPHT diamond supplier guide explain the two growth methods.

Buying Yellow Colored Diamond in the USA, UAE, Japan and Australia

The yellow range is the same, but the trade rules around it differ by market. Liora Diamonds' country pages state the following.

Each page says its guidance is not legal or tax advice and recommends checking import rules with a customs broker. Liora Diamonds' shipping policy sets out how shipping works. For market context, see our guides on sourcing 5 carat+ lab-grown diamonds for U.S. jewelers, lab-grown diamond wholesale trends in the USA, and the lab-grown diamond supplier in Dubai.

Words Buyers Search for Yellow Stones

If you publish your own listings, the vocabulary matters. These are the phrases shoppers and buyers use for the same stones, and how to handle them without misleading anyone.

• "Yellow lab grown diamond", "lab created yellow diamond", "man-made yellow diamond" all describe a stone with the same chemistry as a mined diamond, grown in a lab. Use "laboratory-grown" in product titles so the origin is never in doubt.
• "Fancy vivid yellow lab grown diamond", "fancy intense yellow lab grown diamond" are report-style searches. Match them to the exact grade on the certificate.
• "Loose yellow lab grown diamonds wholesale", "yellow lab grown diamond supplier" are trade searches. They want carat, shape, report, and a fast quote.
• "Yellow lab grown diamond price", "yellow lab grown diamond cost per carat" are price-led searches. Prices vary by carat, intensity, clarity, and shape, so Liora quotes on request for the stone you name.
• "Yellow lab grown diamond engagement ring" and "canary diamond ring" are retail searches. Your customers use them even when you buy at wholesale.
• "Lab grown yellow diamond vs natural" is a comparison search. Keep the answer factual: same material, different origin, disclosed on the report and invoice.

Spelling differs by market: buyers in the UK, Australia and New Zealand write "colour" and "jeweller", while US and Canadian buyers write "color" and "jeweler". Cover both in your listings. Our complete guide to the 4Cs of lab-grown diamonds gives the language for clarity, cut and carat.

Frequently asked questions

1. How can I tell Fancy Intense Yellow from Fancy Vivid Yellow before I buy?

Do not rely on a catalogue image. Screen colour varies with the display, the lighting, and the camera, and Liora Diamond advises asking for a video under daylight. Ask for the report number, then compare the grade line, measurements, and comments against the video of the exact stone. Vivid is the stronger of the two grades in saturation. If the two grades look close, put both stones side by side in the same video, and decide using the setting you plan to use.

2. Do lab-grown yellow diamonds fade?

Liora Diamonds' fancy colour page says the colour of lab-grown fancy stones is stable in normal wear. Normal wear means everyday jewellery use, not exposure to extreme heat or unusual processes, so give your customers ordinary care advice and ask the supplier for any care limits on the specific stone. Keep the report with the stone, since it records how the colour was produced, and make sure your retail paperwork repeats that the stone is laboratory-grown.

3. Is a Grayish, Brownish, or Orangey modifier a problem?

A modifier is not a defect, but it changes the colour. GIA states that pure yellow diamonds are rarer and more desirable than those with brownish or greenish modifiers. An Orangey Yellow gives a warmer, more golden tone, and a Grayish Yellow looks softer and more muted. If your customer wants a clean canary-style yellow, write "no modifier" in the RFQ. If you are open to variety, ask the trade desk to show modified grades at a different price.

4. Do you have yellow lab-grown diamonds above 20 ct?

Liora Diamonds' yellow range includes a 21.00 ct Fancy Intense Yellow heart and a 20.09 ct Fancy Intense Yellow oval, both IGI-graded CVD stones. Stock moves through the day, and selection pages show only a sample of what the trade desk can see, so confirm that a specific stone is still available before you plan a design around it. For anything beyond the listed range, send your brief with the shape, size band, and colour you need.

5. What minimum order and payment terms apply to yellow stones?

Liora Diamonds' trade pages state a minimum of US$2,000 per order, trade buyers only, with singles and parcels allowed to be combined to reach it. Payment is by bank transfer against a pro forma invoice, and quotes are usually returned within one business day. A single large yellow stone will clear the minimum comfortably, while a small parcel may need to be combined with other stones. Ask the trade desk how the minimum applies to your mix.
