The price difference is not a discount. It is not a sign of inferior quality. It is what happens when you remove five layers of supply chain infrastructure from the cost of a stone.
The first question most people ask about a lab-grown diamond is some version of: what is the catch? The price is lower, so something must be wrong with it. That is a reasonable instinct. In most categories, cheaper means compromised. In this one, it does not — because the price difference has nothing to do with the stone. It has everything to do with the infrastructure that surrounds the stone in the mined category, and that does not exist in the lab-grown one.
40 to 60%lower cost for same IGI gradeA D Colour VVS1 Excellent Cut lab-grown diamond costs 40 to 60 percent less than the same specification in mined. The grade is identical. The price is not.
5 to 7intermediaries before retailA mined diamond passes through a mine, rough trader, sorting facility, cutting factory, polished wholesaler, and manufacturer before it reaches a retailer. Each adds margin.
Zeroextraction cost in lab-grownNo mine. No heavy machinery. No intercontinental transport of rough material. The stone grows in a sealed chamber and moves directly to cutting.
Where the Price of a Mined Diamond Actually Comes From
A rough diamond does not go directly from mine to ring. It travels through a rough diamond trader, a sorting and valuation facility, a cutting factory, a polished diamond wholesaler, and a jewellery manufacturer before it reaches a retailer. Each of those stops adds margin. None of them improves the stone.
What You Are Actually Paying For
Mined Diamond · Every Cost LayerWhat goes into that price
1Mine OperationsOpen-pit excavation, diesel machinery, explosives, dewatering, safety compliance, and environmental remediation. This is the single largest cost component.
2Rough Diamond TradingDiamond mining companies sell rough through controlled channels — historically De Beers' sightholder system. Traders buy and resell rough at a markup before it reaches a cutting factory.
3Sorting and ValuationRough diamonds are sorted by quality, size, and shape before cutting. This is a skilled and labour-intensive process that adds cost before the stone has even been polished.
4Cutting and PolishingOver 90 percent of the world's rough is cut in Surat. Skilled labour, planning software, polishing equipment. This step improves the stone, unlike the ones before it.
5Polished WholesalePolished stones are sold through wholesalers to jewellery manufacturers. Another margin layer on top of every cost that came before.
6Marketing OverheadDe Beers spent decades and billions building the cultural association between mined diamonds and love. "A Diamond is Forever" launched in 1947. That advertising history is embedded in the retail price of every mined stone sold today.
Lab-Grown Diamond · The Same Cost ExerciseWhere the money actually goes
1CVD Chamber EnergySustained microwave energy input over 3 to 6 weeks per batch. The single largest cost component. No extraction, no explosives, no dewatering.
2Seed Crystal and GasA thin diamond seed and methane or hydrogen gas. The raw inputs for growth. Both are far cheaper than moving 250 tonnes of earth per carat.
3Skilled Facility LabourGrowing, monitoring, and quality-checking diamond batches requires trained technicians. This cost exists and is real.
4Cutting and PolishingIdentical to mined. The rough crystal is cut and polished using the same techniques, often in the same facilities in Surat.
5IGI CertificationEach stone is graded independently. The certificate has a cost. It is worth every rupee of it.
6Direct to ManufacturerNo rough trader. No polished wholesaler. The stone moves from facility to jewellery manufacturer to buyer. Two or three intermediaries at most, not six.
Lower Price Does Not Mean Lower Grade
The IGI grading certificate does not have a field for origin. It does not have a field for price. A D Colour VVS1 Clarity Excellent Cut lab-grown diamond and a D Colour VVS1 Clarity Excellent Cut mined diamond both say the same things in the same columns. The grade is the grade. The stone that sits in front of an IGI grader gets assessed on its optical and physical properties, not on where it grew.
When two stones have identical 4C grades, they are optically identical. You cannot see the origin through a loupe. You cannot see it with the naked eye. The price difference exists entirely in the infrastructure that surrounds the production of each stone — not in the stone itself.
"A cheaper price earned through removing unnecessary cost is not a compromise. It is just an accurate price."
What the Price Difference Actually Gives You
01A larger stone, same budgetA budget of ₹18,000 that would buy a 0.20ct mined diamond stud buys a 0.35ct lab-grown at the same quality grade. The ring looks meaningfully different at the same spend.
02A better grade, same sizeInstead of a VS2 I Colour, your budget now reaches VVS1 E Colour at the same carat weight. The stone looks cleaner and brighter to the naked eye.
03A better metal, same stoneThe saving on the diamond moves you from 14K gold to 18K gold, or from gold to platinum. The setting you actually wear every day becomes better.
How VAIMA Prices Specifically
Most jewellery brands publish a price and tell you nothing about how they arrived at it. VAIMA prices from the bottom up and discloses every component on the invoice.
Metal Weight1.6g stated on invoice
Gold Rate (IBJA)Live rate at time of purchase, stated in ₹/g
Metal CostWeight × IBJA rate = verifiable number
Making ChargeDisclosed as a % of metal cost, not hidden in MRP
Diamond CostStated separately. IGI cert number alongside.
GST3% — stated as a line item
TotalEvery component verifiable by the buyer
There is no MRP on a VAIMA piece. There is no inflated sticker price that creates a manufactured discount. The number on the product page is what the piece costs to make, plus a margin that allows VAIMA to exist as a business. You know every component. You can verify the metal cost against the IBJA rate yourself. This is what specification transparency looks like in practice.
The One Place Where Lower Price Is a Caveat
Lab-grown diamonds currently depreciate more steeply on resale than mined. This is worth stating plainly. If you buy a lab-grown diamond today and try to sell it in five years, you will recover less of the purchase price than you would with a mined stone at comparable grade.
For buyers who are thinking about jewellery as an investment, this matters. For buyers who intend to wear the piece, which is most people, it does not. A piece of jewellery worn daily does not sit in a safe depreciating. It does what jewellery is supposed to do.
On resale generally: Both categories depreciate significantly at retail. A mined diamond bought at retail for one lakh rupees does not sell for one lakh rupees on the secondary market. The resale difference between lab-grown and mined matters only if you are buying specifically to sell. Most buyers are not.
"A lower price for a lab-grown diamond is not a concession. It is an accurate price for what the material costs to produce, without the overhead of a century of marketing, the margins of five intermediaries, and the operational cost of moving 250 tonnes of earth per carat built into it."
