When buying a diamond, most of us have two immediate questions: “How much will it cost?” and “Am I getting good value?” In 2025, the price conversation has a new layer: the rise of lab-grown diamonds.
They look identical to natural diamonds, but their pricing story is very different. Are lab diamonds really more affordable? How do price trends compare? And what about long-term value?
This guide contributed by Rare Carat breaks down the numbers, the trade-offs, and what it means for buyers today.

Are Lab-Grown Diamonds More Affordable?
Yes and the difference is striking.
Lab-grown diamonds typically cost 40–70% less than mined diamonds of the same size and quality. That’s because rarity is what drives the premium on natural diamonds, while lab-grown stones can be produced more efficiently.
For example, a well-cut 1-carat, G-color, VS1 diamond might cost around $5,000–6,000 if mined, but only $1,000–2,000 if lab-grown.
This affordability lets buyers either:
- Stay within budget but get a larger stone.
- Or stick with their preferred size and channel the savings into settings, wedding bands, or honeymoon costs.

Pricing Trends: Lab-Grown vs. Natural
Diamond pricing doesn’t stand still. Here’s how the market has been evolving:
Mined Diamonds
- Prices are influenced by global supply, mining costs, and demand.
- Generally hold more stable long-term value because rarity cannot be replicated.
- Resale potential is higher, though like any luxury, depreciation still applies.
Lab-grown Diamonds
- Prices have steadily dropped as production technology (HPHT or CVD) improves and supply increases.
- Resale value is lower and less predictable, as secondhand markets are still developing.
- For buyers focused on initial purchase value, LGDs are the clear winner.
Cost Comparison in a Glance
| Factor | Lab-Grown Diamonds | Natural Diamonds |
| Average 1-Carat Price (2025) | $800–$2,500 | $5,000–$6,500 |
| Price Trend | Decreasing (tech-driven) | Stable to increasing (supply-driven) |
| Resale Value | Lower, limited market | Stronger resale dynamics |
| Value Per Carat | 40–70% more affordable | Premium for rarity |
What About Resale & Investment Value?
This is where expectations need to be clear.
Natural diamonds: Historically retain stronger resale value due to rarity. Some buyers even treat them as generational assets.
Lab-grown diamonds: Resale is still limited. Think of them like technology: the upfront savings are the benefit, but long-term investment shouldn’t be the expectation.
For engagement rings and jewelry meant to be worn (not resold), many buyers happily accept this trade-off in exchange for upfront affordability and design flexibility.

The Real Pricing Story
Lab-grown diamonds are more affordable, often dramatically so. They make larger sizes and higher qualities accessible to more buyers. But the affordability also comes with trade-offs in the resale cost.
If your priority is value, beauty, and ethical alignment at the time of purchase, lab grown diamonds are hard to beat. If rarity and future resale matter most, naturals hold the edge.
Rare Carat’s takeaway: Use transparency to your advantage. With side-by-side comparisons, AI scoring, and expert reviews, you don’t just buy a diamond; you buy it smart, at the right price, for your priorities.
