What Affects Lab Grown Diamond Cost
Lab grown diamonds cost varies based on several factors. Understanding these helps you make smarter decisions and get better value for your budget.
The 4Cs: Cut, Clarity, Colour, Carat
Just like natural diamonds, lab grown diamonds are graded on the 4Cs. Each factor affects price:
- Carat Weight: The biggest price driver. A 2 carat diamond costs significantly more than two 1 carat diamonds of equal quality
- Cut Quality: Excellent cut commands 10-15% premium over Good cut. Worth paying for since cut determines sparkle
- Clarity: VVS and VS grades are ideal. Going below SI1 saves money but inclusions become visible
- Colour: D-F (colourless) costs more than G-J (near colourless). Most people can’t tell the difference between E and G
Key Finding: Lab grown diamonds cost 60-70% less than natural diamonds of identical 4C specifications. A 1 carat E/VVS2 lab grown diamond costs what a 1 carat H/SI1 natural diamond costs.
Metal Choice
The gold setting adds significantly to final price:
- 14K Gold: Most affordable, very durable, slightly lighter colour
- 18K Gold: Best balance of purity and durability, most popular choice
- 22K Gold: Richest colour, highest gold content, softest (less ideal for daily wear rings)
Setting Complexity
A simple solitaire setting costs less than a halo setting with additional accent diamonds. More intricate designs require more labour and materials.

Why the Price Difference?
Natural diamonds take billions of years to form and require expensive mining operations. Lab grown diamonds are created in weeks using advanced technology. The production cost is fundamentally different.
According to IGI (International Gemological Institute), both types are graded using identical standards. The certification process doesn’t distinguish quality, only origin.
Key Finding: Lab grown diamonds offer the same physical properties as natural diamonds at 60-70% lower cost. The savings can fund a larger stone, better setting, or simply remain in your pocket.
How Gold Purity Affects Lab Grown Diamond Cost
The same diamond in different gold purities will have different total prices. Here’s how metal choice impacts your final cost.
| Gold Purity | Gold Content | Price Impact | Best For |
|---|---|---|---|
| 14K Gold | 58.3% | Lowest | Daily wear rings, durability |
| 18K Gold | 75% | Mid-range | Best balance, most popular |
| 22K Gold | 91.6% | Highest | Traditional look, softer metal |
For the same diamond ring, expect roughly:
- 14K to 18K: 15-20% price increase
- 18K to 22K: 20-25% price increase
Gold Colour Options
All three colours, yellow, white, and rose gold, are available at the same price point within each purity level. Choose based on personal preference and skin tone, not cost.
How to Get the Best Value on Lab Grown Diamonds
Smart shopping can save you 20-30% without sacrificing quality. Here’s how.
1. Go Slightly Under Popular Carat Weights
A 0.95 carat diamond looks identical to 1 carat but costs noticeably less. Same applies to 1.9 vs 2 carat, 2.9 vs 3 carat. The eye can’t tell the difference, but your wallet will.
2. Prioritise Cut Over Everything
An excellent cut G colour diamond sparkles more than a poor cut D colour diamond. Cut determines 80% of a diamond’s visual appeal. Never compromise here.
3. Choose VS Clarity
VVS clarity is nice on paper, but VS1 and VS2 are “eye clean”, meaning you can’t see inclusions without magnification. Save 15-20% by choosing VS over VVS.
4. Consider G-H Colour
D-F diamonds are technically colourless, but G and H appear nearly identical once set in jewellery. Especially in yellow gold settings, G-H colour saves money without visible compromise.
5. Look at Total Value, Not Just Diamond
A well-designed setting can make a smaller diamond look larger. Halo settings, for example, add visual size without the cost of a bigger centre stone.
Key Finding: Buying a 1.9 carat diamond instead of 2.0 carat saves ₹8,000-15,000 with no visible difference. The same principle applies at every popular carat threshold.

Frequently Asked Questions
How much does a 1 carat lab grown diamond cost in India?
A 1 carat lab grown diamond ring in 18K gold costs between ₹50,000 to ₹90,000 depending on cut, clarity, and colour. The same specifications in a natural diamond would cost ₹1.5-2.5 lakh. All our diamonds are IGI certified with VVS/VS clarity.
Why are lab grown diamonds so much cheaper than natural diamonds?
Lab grown diamonds are created in weeks using advanced technology, while natural diamonds form over billions of years and require expensive mining operations. The production cost is fundamentally different, resulting in 60-70% lower prices for identical quality.
Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are chemically, physically, and optically identical to natural diamonds. Same carbon structure, same hardness (10 on Mohs scale), same brilliance. They’re certified by IGI and GIA using identical standards. The only difference is origin.
What is the cheapest lab grown diamond jewellery I can buy?
Lab grown diamond jewellery at Chaitra starts from ₹11,599 for everyday pendants. Diamond bands start at ₹19,499 and studs start at ₹19,899. All pieces include IGI certified diamonds and BIS hallmarked gold.
Is 14K or 18K gold better for lab grown diamond jewellery?
Both are excellent choices. 14K gold is more affordable and durable, making it ideal for daily wear rings. 18K gold offers a richer colour and is the most popular choice. The price difference is typically 15-20% between them.
Do lab grown diamonds hold their value?
Lab grown diamonds have lower resale value compared to natural diamonds because production isn’t limited by mining. However, Chaitra’s lifetime exchange (gold at 100% and diamonds at 90% of today’s value) and lifetime buyback (gold at 100%, diamond at market value less 15%) mean you can upgrade or sell back later on clear terms.
How much does a lab grown diamond engagement ring cost?
Solitaire engagement rings with lab grown diamonds start at ₹42,399. Most customers spend between ₹80,000 to ₹2 lakh for engagement rings, getting significantly larger diamonds than they would with natural stones at the same budget.
What affects the cost of lab grown diamonds most?
Carat weight is the biggest factor, followed by cut quality. A 2 carat diamond costs more than double a 1 carat of the same quality. Cut quality affects price by 10-15%, while clarity and colour differences impact price by 5-10% per grade.
Are lab grown diamond prices dropping?
Lab grown diamond prices have stabilised in recent years after initial decreases. The technology is mature and pricing reflects current production costs. We don’t anticipate dramatic price drops, but lab grown remains 60-70% cheaper than natural.
How much does a lab grown diamond tennis bracelet cost?
Tennis bracelets with lab grown diamonds start at ₹47,199 and go up to about ₹5.4 lakh depending on total carat weight and diamond size. A similar natural diamond tennis bracelet would cost ₹1.5-20 lakh.
What is the best carat size for value?
Go slightly under popular thresholds: 0.9 instead of 1 carat, 1.9 instead of 2 carat. These “shy” sizes cost less but look identical. For maximum visual impact per rupee, consider cluster or halo settings that make diamonds appear larger.
Does diamond shape affect lab grown diamond cost?
Yes. Round brilliant is typically 15-20% more expensive than fancy shapes like oval, pear, or cushion. Oval and pear shapes also appear larger than rounds of the same carat weight.
How do I know I’m getting fair pricing on lab grown diamonds?
Look for transparent pricing that shows diamond cost, gold cost, making charges, and GST separately. At Chaitra, we show complete price breakdowns on every product. All diamonds come with IGI certification you can verify independently.
What’s the price difference between yellow, white, and rose gold?
All three gold colours are priced identically within each purity level. The choice between yellow, white, or rose gold is purely aesthetic. Choose based on your skin tone and style preference, not cost.
