Three stones, three very different value propositions. Here is the bench-level comparison we give every client.
The numbers
Moissanite: Mohs 9.25, refractive index 2.65, fire 0.104 (high), 1ct-equivalent $300–$800, GRA certified. Lab-grown: Mohs 10, RI 2.42, fire 0.044, 1ct-equivalent $1,500–$3,000, IGI/GIA. Natural: Mohs 10, RI 2.42, fire 0.044, 1ct-equivalent $5,000–$15,000+, GIA/IGI.
What this means for you
Moissanite flashes rainbow. Under a bright restaurant light it looks festive; under office fluorescent it can look over-sparkly. Some clients love it; others return the ring after a week. If you want the classic, quiet "ice" look, pick a diamond.
Lab-grown diamond is the sweet spot for most of our clients: natural diamond optics, 70% less than natural, ethically sourced, and a real certificate. It holds value less than natural, but you are buying it to wear, not to flip.
Natural diamond matters if you want heirloom resale value, or if the ring will be passed down. We source GIA stones at near-wholesale because we have direct supplier relationships.
Common myth busted
"Moissanite is a fake diamond." No — it is a real mineral with its own refractive index. It is to diamond what sapphire is to ruby: a different stone, not an imitation. Read more on our materials page.

How the three stones compare under bench light
When a buyer asks which stone to choose, we do not rely on marketing photos. We set one stone of each type in the same setting, check it under a retail-style spotlight, an office fluorescent and a soft outdoor window, and compare how the light returns across the crown, the pavilion and the side profile. Moissanite returns a higher, more dispersed rainbow flash; lab-grown diamond returns a closer match to natural diamond white brilliance; natural diamond carries the heirloom character and secondary-market history the other two do not. The right choice depends on the wearer's taste, the daily setting and the long-term budget, not on whichever slogan the latest campaign repeats.
| Attribute | Moissanite | Lab-grown diamond | Natural diamond |
|---|---|---|---|
| Hardness | Mohs 9.25 | Mohs 10 | Mohs 10 |
| Optical character | High rainbow fire | White brilliance, diamond-like | White brilliance with natural character |
| Typical price | Lower per carat | About 70% below natural | Highest per carat |
| Supply | Lab-created, consistent | Lab-created, consistent | Mined, graded individually |
| Resale | Limited secondary market | Limited secondary market | Established resale history |
Reading the price gap realistically
The per-carat difference is real, but it should not be read in isolation. A lower stone price can still be offset by a heavier metal setting, a more intricate cut or a smaller production run. Before quoting a comparable ring, we price the stone, the metal weight, the setting labor and the finishing separately so the buyer can see where the money sits. Many of our wholesale clients start with a moissanite or lab-grown pilot run, then move natural diamond into their premium line once the collection sells through.
It is also worth separating the ring you propose to stock from the ring you personally would keep. Retail buyers compare face-up size, color consistency and comfort, not only the carat number. A well-set 1 carat-equivalent stone often looks larger and more even than an under-set slightly larger one, which is why setting proportion matters as much as the stone itself.
Everyday wear and durability
All three stones are hard enough for a daily ring, but they behave differently over years of wear. Prong seating, side-stone alignment and a protective setting do most of the long-term work; a stone that sits too high catches clothing, and one that sits too low risks chipping at the pavilion. We check stone seating under magnification before packing and advise on finish options for hands that work outdoors, in kitchens or with tools.
Metal choice changes the maintenance story too. Sterling silver with rhodium plating brightens a piece but will eventually need replating; yellow or rose gold is more forgiving on surface scratches; platinum patinas and can be brushed back to a soft finish. The stone decision and the metal decision should be made together, because the setting does most of the visible work after the first year.
What wholesale and private-label buyers should ask
Before comparing suppliers, it helps to write down the questions that affect both your margin and your after-sale support:
- What is the minimum order for samples, and what is the MOQ for a bulk reorder?
- What lead time applies to sampling, and what bulk production window should you plan around?
- What certification or grading report accompanies each stone type?
- What plating, warranty and repair terms cover the finished ring?
- Can the supplier match an existing design, a reference photo or a CAD sketch?
Suppliers that answer these in writing, rather than only with a round number, are easier to build a repeat collection around. Our design team replies within two hours on weekdays with a quotation, production window and any practical alternatives to the reference you send.
Certification and disclosure we provide
Every stone type in our collection is presented under its correct name. Moissanite is described as moissanite, lab-grown diamond as lab-grown, and natural diamond with its grading source; we do not blend names in listings, cards or descriptions. Where a piece carries a lab report, the report type and date are recorded with the order, and material reports on nickel, lead and cadmium release are available for wholesale buyers who request them.
If your market requires a specific disclosure wording on the setting card or the website, send us the requirement and we will match the wording in the product record. Transparent labeling protects both the end buyer and your store's reputation; a misnamed stone is the one complaint that is difficult to resolve after delivery.
Choosing a stone for the wearer
For a daily ring that goes to work, the priority is a secure setting and a stone that reads cleanly in ordinary indoor light. Moissanite's strong fire can suit a brighter, more festive look; lab-grown diamond is the safer middle choice when the buyer wants diamond-like appearance without the natural-diamond premium. For a wedding or engagement piece that will be passed along, natural diamond carries the documented provenance and heirloom history that the other two cannot match on the secondary market.
Tell us how the ring will be worn and who will wear it, and we can narrow the recommendation to two stone types instead of a full comparison. Comfort, hand shape and finger size matter here too; a stone that looks striking in a catalog can sit differently once it is set on the wearer's hand.
Common purchase mistakes to avoid
The most common mistake is choosing the stone before the setting. A large stone in a thin, insecure band can look unfinished after a few months of wear, while a balanced setting makes a more modest stone look deliberate and even. The second mistake is comparing per-carat prices without asking what the total finished ring costs, including metal, stones and labor. The third is skipping the disclosure check, which can leave your store responsible for a listing that the end buyer later reads as misleading.
Send us a reference photo or a hand sketch rather than a generic search result, and we will explain which part of the design is practical to reproduce, which stone fits the budget, and where a comparable alternative would save money without changing the look you want.
How stone and setting work together
The stone and the setting are not two separate decisions; they read as one piece once the ring is worn. A narrow band can make a larger stone look balanced, while a wider setting can visually fill the finger and carry a center stone more evenly. Before settling on a stone size, ask how the head, shoulders and band will support it, because a setting that dominates the stone will make the center piece look secondary, and a setting that disappears can leave the stone appearing unsupported.
Side stones and accents change the comparison too. A few matched side stones extend the line of the center stone across the finger, which is why our bench sets side stones in matching color and cut before photographing the finished piece. If you plan to stock a matching wedding band, that curve and fit should be considered at the render stage rather than added later, when reshaping the band can disturb the existing stones.
Frequently Asked Questions
Q: Is moissanite a fake diamond? No. Moissanite is a real, durable mineral with its own refractive index and fire. It is a separate stone type, not an imitation passed off as diamond, and it should be labeled correctly in every listing.
Q: Which stone gives the best value for a wholesale pilot collection? Most of our buyers start with moissanite or lab-grown pieces for the pilot run, because the per-carat cost leaves room for a stronger setting and a sharper margin; natural diamond is usually added to the premium line after the first collection sells through.
Q: How do you confirm the stone type before packing? Each order is checked against its stone type, seating and finish under magnification before dispatch, and the accompanying report or certification is recorded with the order number.

Frequently Asked Questions
Is moissanite a viable diamond alternative for retail?
Yes for price-sensitive buyers who want brilliance and hardness. It ranks 9.25 on the Mohs scale and costs a fraction of a natural diamond of the same size, so it turns fast in bridal and fashion lines.
What is the minimum order?
MOQ starts at 50 pieces per design for stock items; custom cuts and private-label settings start at 100 to 300 pieces.
Are certificates included?
Yes. Every parcel ships with GRA or IGI documentation listing carat weight, colour grade and cut.
What are the lead times?
Samples 3 to 5 days. Bulk 15 to 20 days under 500 pieces, 25 to 30 days for custom work.
