Lab-Grown Price Trends & Depreciation
Lab-grown diamonds can be a strong choice for fashion jewelry, studs, and upgrade-friendly pieces. Still, Diamond Pricing for lab-grown stones can change quickly, and resale is often limited. This guide explains what's going on so you can buy with clear expectations.
Quick answer: Should you buy lab-grown?
Lab-grown is usually a great fit if you want more size for the budget and you plan to keep the piece. It's a weaker fit if you expect strong resale value later or you're shopping for scarcity.
Simple rule:
- Lab-grown fits "best look for the money."
- Natural often fits "long-term value behavior."
If you're buying a statement piece and you'd rather keep cash in your pocket than pay for rarity, lab-grown can feel like a win. Just assume the payoff is in wearing it, not in selling it.
Why lab-grown prices change
Technology gets better (and cheaper)
Lab-grown stones are made with industrial growth methods. When growth and treatment methods improve, the cost to produce similar stones can fall. GIA's lab-grown trends research summary notes a jump in submissions of colorless-grade (D–F) CVD diamonds in 2020 and connects it to refinements in growth and post-growth processes.
Supply can scale
Natural supply is limited by mining. Lab-grown supply can expand when more growers add capacity. In 2025, Reuters reporting cited analysis that wholesale prices for one- and two-carat lab-grown diamonds fell by as much as 96% since 2018, with oversupply and rising production as major drivers.
Retail competition is intense
When many stores can offer similar lab-grown stones, price becomes the easiest lever to pull. That competition can push prices down across the board, which is great for buyers today, but it can also affect "what it's worth later."
What "depreciation" means in real life
Depreciation = the gap between what you paid at retail and what a new buyer will pay later.
With lab-grown, that gap can feel bigger because new lab-grown prices may keep moving down, and buyers can often shop new with wide selection. So a pre-owned stone usually has to be priced low enough to feel worth the tradeoff.
Replacement value vs resale value (don't mix them up)
- Replacement value is what it costs to replace a similar piece at today's prices through normal retail channels.
- Resale value is what someone is willing to pay you, with fewer guarantees and many other options.
If you want flexibility, resale is not the only path, upgrade policies can matter more.
How to buy lab-grown with confident expectations
1) Decide what you want your diamond to do
Pick your main goal: big look for the budget, daily-wear beauty, or upgrade flexibility. If your real goal is future resale, compare natural options too.
2) Put your attention on what your eye sees
For lab-grown, daily happiness often comes from strong cut quality, a shape you truly love, and a setting that fits your lifestyle.
3) Treat upgrade policies as the "value path"
The market is shifting fast. McKinsey's diamond industry analysis describes the industry as being at an inflection point, including pressure from lab-grown competition and the need for companies to adjust how they connect with customers.
Before you buy, get the upgrade terms in writing:
- How much credit do you get toward an upgrade?
- Minimum spend, time limits, or other conditions?
- Do you have to buy the new stone from the same seller?
4) Make sure the product is described clearly
You should never be left guessing whether a stone is natural or lab-created. The FTC's guidance on advertising diamonds and gemstones explains that claims must be accurate and that sellers should disclose material information, including when a product is laboratory-created.
A quick expectations checklist
Before you buy, make sure you can answer these questions:
- Am I buying this to wear and love, or to sell later?
- If prices fall next year, will I still feel happy with the piece?
- Do I have an upgrade option I trust, in writing?
- Are the return terms clear for my timeline?
What price trends suggest right now (without drama)
Lab-grown can deliver strong value today, but buyers should expect pricing to keep changing. As one snapshot, BriteCo's 2025 lab-grown vs natural report says a 1-carat lab-grown diamond averaged $1,000 or less at retail, while a natural 1-carat diamond averaged around $4,200.

Frequently Asked Questions
They can. If new lab-grown prices fall, a pre-owned stone often has to sit lower to attract a buyer. Buy lab-grown for beauty and budget, not for resale. The depreciation you might experience is typically steeper than with natural diamonds due to the scalable nature of production.
Production can expand quickly, and retailers compete hard on price. More supply plus tight competition often leads to lower prices. Improvements in manufacturing technology also reduce production costs, which gets passed down through the supply chain.
No. If you want size and sparkle while staying on budget, lab-grown can be a great fit. The key is knowing what the purchase is (jewelry) and what it isn't (an investment). For buyers focused on getting the most visual impact for their budget today, lab-grown makes excellent sense.
You can try, but offers can vary and may be far below retail. If flexibility matters, upgrade policies can be more useful than resale. The secondary market for lab-grown is still developing, and prices there are often heavily discounted from retail.
Confirm clear disclosure that the stone is lab-created, verify the grading paperwork, and get return and upgrade terms in writing. Also check that the lab report clearly indicates it's a lab-grown diamond, and understand the seller's policy if you want to upgrade to a different stone later.
