5 Carat Lab-Grown Diamonds Wholesale: Shapes, Grades and Price Steps

A 5 ct lab-grown diamond is the point where a jeweler's order stops being routine. Shape, color intensity, and exact weight, against 5.00 ct, move the price more than they do at 1 or 2 carats. Specify those three things, ask for an IGI report on the stone, and ask for quotes at two nearby weights. That is how trade buyers keep 5 ct purchases predictable.

Liora Diamond lists 5 carat+ stones for trade buyers on its loose diamonds listing. Prices are not shown online. Each stone has a Price button that opens a WhatsApp quote request, and the trade minimum is US$2,000 per order.

Who Buys 5 Carat Stones, and For What

Most 5 ct+ inquiries come from three kinds of buyers:

• Bridal and fine-jewelry retailers who want a center stone for a client's engagement ring or a made-to-order piece.
• Independent jewelers and designers who sell one-off pieces and need a stone that photographs and sells as a statement.
• Manufacturers and brands who build collections around a few large stones and need the next one to match the last.

A 5 carat stone is rarely a stock-room commodity. Buyers usually have a client or a collection waiting, which is why the question is rarely "what is the cheapest 5 carat?" and usually "which 5 ct will work for this setting and this customer, and can I see it on video before I commit?"

If your orders sit well below 5 carat, our 1 carat wholesale guide covers that range. For a complete overview of bulk sourcing lab-grown diamonds for the USA, see our guide.

Shapes at 5 Carat and How Big They Face Up

Carat is weight, not size. A 5 ct stone's face-up spread depends on its shape and cut. As a rough industry reference, a 5 ct round brilliant measures around 11 mm across. Elongated shapes such as oval, pear, radiant, and emerald spread their weight over a longer outline, so they usually look larger than a round of the same weight. That's why oval and radiant stones are so common in this size.

Liora's 5–9.99 ct includes oval, radiant, cushion, pear, heart, and lily-cut. Examples from the live listing:

When a client wants "the biggest look for the weight", ask for elongated shapes. When a client wants a heart or lily cut, expect fewer options and compare stones individually, since cut quality varies more on fancy shapes. The cut grade is not shown on every listing, so ask for the video and proportions before you quote a client.

Color and Clarity Choices that Hold Value

For white stones, Liora's wholesale lab-grown diamonds lists typical grades for big stones as D–G color and VVS–VS clarity, with an IGI report. That range covers most white-stone demand at this size. A 5 ct stone shows inclusions more easily than a 1 ct stone, so clarity matters more as weight rises.

For fancy-color stones, the choice comes down to color intensity. Fancy Intense and Fancy Vivid are the grades that dominate current 5 ct listings. The more saturated the color, the more it drives price, and the more important it is for pairs or sets to match. If you are choosing between intensities, compare the stones on video in daylight-equivalent light, not just the grade on the report. Our upcoming guide on Fancy Intense vs Fancy Vivid goes through this in detail.

A practical way to specify:

Price Steps Around 5.00 Carat Weights

Diamond weight is recorded to the thousandth of a carat and rounded to the nearest point, with one point being one hundredth of a carat. Round weights act as pricing thresholds. GIA describes certain round weights as "magic sizes" and notes that a stone just over one can cost markedly more for only a few extra points of weight. GIA also notes that larger stones cost more per carat because large diamonds are rarer. GIA's example applies to natural diamonds, and lab-grown pricing varies by supplier, so don't assume the same percentages apply. The practical principle holds across the trade: a stone at 4.90 ct and one at 5.02 ct are separated by a pricing step, and the visual difference between them is small.

What to do about it:

1. Quote the same shape and grade at two weights, e.g., 4.90–4.99 carat and 5.00–5.10 carat, and compare. If your client buys based on appearance, a 4.9x stone may cost less per stone.
2. Check the true weight on the report. A listing that says "5 ct" can be 4.98 or 5.07.
3. Ask for the price per stone and per carat, and keep the comparison on a single basis.
4. Don't compare across color grades without comparing the video. Two Fancy Intense stones can look very different.

Liora does not publish 5 ct prices, because they change with stock and spec. Ask for a quote on the specific stones you shortlist.

5 Carat White vs Fancy Color Laboratory-Grown Diamonds

At Liora, the 5-carat-weight diamond catalog is dominated by fancy color. A 6 October 2026 snapshot found 239 stones at 5 carat weights+, 184in the 5–9.99 ct band; 233 of the 239 are fancy color, and 6 are white. The first 24 stones on the 5–9.99 ct listing on 8 October were all fancy color (pink and yellow). On the big diamonds collection page, every size is available in white and fancy color, and 5–10 ct is "stock and short lead time." So if you need a white 5 ct stone, send your spec to the trade desk rather than relying on the online listing alone. We don't promise a specific white stone until the desk confirms it.

FAQ

1. Is a 4.9 ct lab-grown diamond cheaper than a 5.0 ct?

Usually, yes. Wholesale lab-grown diamond suppliers price in steps at round weights, so a stone just under 5.00 ct is normally quoted lower than one at or above it, even though the two look almost identical face-up. GIA calls these round weights "magic sizes" for natural diamonds, and Liora quotes each lab-grown stone individually. A practical approach is to ask your trade desk for the same shape, color, and clarity at two weights, for example 4.90 to 4.99 ct and 5.00 to 5.10 ct. Compare the per-stone price and the video, then choose the weight your client will actually notice.

2. Which color and clarity grades do buyers choose at 5 carat?

For white stones, Liora's Wholesale Diamonds typically offers D to G color with VVS to VS clarity and an IGI report for big stones, and that range covers most trade demand at this size. Clarity matters more as weight rises, because inclusions are easier to see in a 5 ct stone than in a 1 ct stone. For fancy color, most current 5 ct stones are Fancy Intense and Fancy Vivid pink and yellow. The right intensity depends on your client, the setting, and your budget, so compare the actual stones on video before choosing, not just the reports.

3. Do 5 ct lab-grown diamonds come with IGI reports?

Yes. Liora's big stones are supplied with an IGI grading report as standard, and GIA grading can be arranged. We share the report before invoicing, along with a report number you can verify online. Before paying, check that the report's carat weight, color, clarity, and growth method match your order, and match the report number to the stone shown on video. Liora's IGI-certified wholesale guide explains these checks in more detail. If you need GIA rather than IGI, state that in your first inquiry so the shortlist is built correctly from the start, not rebuilt later.

4. Which shapes are available at 5 carat in wholesale?

Liora's live 5 to 9.99 ct included oval, radiant, cushion, pear, heart, and lily-cut stones. Elongated shapes such as oval, pear, and radiant usually look larger face-up than a round of the same weight, which is why they are common at this size. Heart and lily cuts offer fewer options, so expect to compare them individually and ask for video and proportions. Stock changes through the day and many stones are not listed online, so send your preferred shape and a fallback shape to the trade desk when you enquire, plus your carat range.

5. Is white or fancy color easier to source at 5 ct?

On Liora's online listing, fancy color dominates at 5 ct and above. Of the 239 stones, 233 are fancy color, and 6 are white; the first 24 stones in the 5 to 9.99 carat view are all fancy color. Stock changes daily. Liora's Big Diamonds are available in every size in white and fancy color, so for a white 5 ct requirement, send your full specification to the trade desk rather than relying only on the online listing. The desk can confirm availability first, before you quote a client.

6. What is the minimum order for 5 ct lab-grown diamonds?

Liora sells to the trade only. Our minimum order starts at $2,000. A single 5 ct stone normally exceeds that, but the minimum matters if you are combining smaller stones or testing a first order. Prices are not shown online. Each listed stone has a Price button that opens a WhatsApp quote request, and you can also use the inquiry form. Confirm the current minimum with the trade desk before you place an order, since terms and stock details can change.

7. What should I include when requesting a 5 carat weight shortlist?

Send everything in one message so the desk can build an accurate shortlist. Include the shape and a fallback shape, a carat range such as 5.00 to 5.99 ct, the color requirement (a white grade, or fancy hue and intensity), minimum clarity, whether you need a single stone or a pair, your report preference of IGI or GIA, the quantity, and your destination country. Liora's process then runs from specification to shortlist, with video, confirmation, a pro-forma invoice, bank transfer, and insured delivery with paperwork. The more precise your brief, the fewer rounds of shortlisting you will need to decide quickly.

8. Can I hold a 5 carat stone while my customer decides?

Liora's wholesale diamonds can hold stock goods while you confirm with your customer, and you can reserve supply against a forecast for ongoing programs. It also says memo can be discussed with established trade accounts after a history of paid orders, and that first orders are invoiced and paid by bank transfer. The page does not state a standard hold length, so ask the trade desk for the exact period when you request your shortlist. Stock goods usually ship within a few business days of payment; made-to-order dates are confirmed before you pay, so ask.
