LAB-GROWN VS. NATURAL DIAMONDS: AN HONEST ANALYSIS OF VALUE & FUTURE
Glacier Ice vs. Freezer Ice. Both are chemically H2O, but their value is vastly different.
It is the elephant in the room. You see the advertisements everywhere: "Real diamonds, half the price." Lab-Grown Diamonds (LGDs) have disrupted the jewelry industry, offering the sparkle of a diamond for the price of an iPhone.
But when something sounds too good to be true, it usually is. While we sell both at Zizov, we believe in radical transparency. There is a dark side to the lab-grown boom that most retailers won't tell you: the catastrophic drop in value.
In this analysis, we look at the numbers, the science, and the future, so you don't wake up in 5 years regretting your purchase.

THE SCIENCE: ARE THEY "REAL"? (AND HOW THEY ARE MADE)
Yes. Chemically, physically, and optically, a Lab-Grown Diamond is identical to a Natural Diamond. If you test it with a thermal pen, it beeps "Diamond."
The Manufacturing Process (Speed Breeding)
There are two ways to grow a diamond:
- HPHT (High Pressure High Temperature): The "Pressure Cooker" method. A seed crystal is placed in carbon flux and subjected to crushing pressure (like the Earth's mantle). This method is used for small stones and often results in yellowish tints.
- CVD (Chemical Vapor Deposition): The "Microwave" method. Methane gas is pumped into a vacuum chamber and broken down into carbon plasma, which rains down on a seed plate. This is how most high-quality large stones are made today.
The Identification: While they look the same to the naked eye, a specialized machine can tell them apart instantly. Natural diamonds contain nitrogen traces (Type Ia), whereas Lab diamonds are pure carbon (Type IIa). They have a different "growth DNA."
THE FINANCIALS: DEPRECIATION VS. RETENTION
This is where the story gets scary for investors. You are not buying an asset; you are buying technology.
The "Moore's Law" of Diamonds
In 2016, a 1-carat Lab Diamond cost about $5,000. Today, you can buy one for $400-$500. That is a 90% drop in value in less than a decade.
Why? Because it is a manufactured product. Factories in China and India are churning out thousands of carats per day. Supply is infinite. When supply is infinite, price trends toward the cost of production (which is falling).
Technology (Lab) gets cheaper every year. Scarcity (Natural) gets more expensive.
The "Lightbox" Effect: In 2018, De Beers launched their own lab-grown brand, "Lightbox," capped at $800/carat. This was a strategic move to anchor the price low and destroy the "luxury" perception of lab diamonds. It worked.
THE RESALE REALITY (THE SUNK COST)
This is the most critical factor for an engagement ring.
Natural Diamonds: They are a store of wealth. While not a stock market investment, they retain intrinsic value. You can trade them in, upgrade them, or sell them. The scarcity (Argyle mine closure, Russian sanctions) drives long-term value up.
Lab-Grown Diamonds: They have ZERO resale value. Once you buy it, the money is gone. Pawn shops and jewelers (including us) generally do not buy back lab diamonds because the wholesale price keeps dropping. A stone you buy for $2,000 today might cost $200 new next year.
Buyer Beware: Lab diamonds are an expense, not an asset. Treat it like a wedding dress—beautiful for the day, but financially sunk.
DEEP DIVE: THE SECONDARY MARKET (WHERE DIAMONDS GO TO DIE)
To understand value, you have to try to sell. Let's look at the actual liquidation channels.
1. The Pawn Shop Test
Walk into a pawn shop with a Lab Diamond.
They will say: "We don't take them."
Why? Because they cannot confirm the price will hold for the 30 days they have to hold it. It is a falling knife.
2. The Auction House (Sotheby's/Christie's)
They do not accept Lab Diamonds. They only deal in natural assets with provenance.
3. The "Upgrade" Policy
Many online retailers offer "Lifetime Upgrades" on Lab Diamonds. Read the fine print.
The Catch: You usually have to spend 2x the original price to use the credit. If you bought a $5,000 stone, you have to spend $10,000 to get your $5,000 credit. You are just digging a deeper hole.
Zizov Policy: We offer 100% credit on Natural Diamonds for any upgrade over the original price (even $1 more).
Read the fine print. "Value" is what you can sell it for, not what you bought it for.
Many brands claim Lab diamonds are "Eco-Friendly." The reality is murky.
The Energy Cost: Creating the pressure of the Earth's core requires massive amounts of electricity. It takes 5,000+ degrees Fahrenheit for weeks.
The Coal Reality: 60% of lab diamonds are made in China and India, often in regions powered by coal grids. A mass-produced lab diamond can actually have a higher carbon footprint than a responsibly mined natural diamond from Canada or Botswana.
The Kimberly Process: Natural diamonds are strictly regulated to ensure ethical sourcing and environmental rehabilitation. The "Blood Diamond" narrative is largely a relic of the 90s, thanks to strict tracking.
A BRIEF HISTORY OF "FAKE" DIAMONDS
To understand where we are going, we must look at where we came from. Lab diamonds are not new.
- 1954 (General Electric): GE creates the first synthetic diamond. It is brown, ugly, and tiny. It is used for industrial drill bits.
- 1970s (Cubic Zirconia - CZ): A diamond simulant (not real diamond) hits the market. It looks fake and scratches easily.
- 2010s (The Breakthrough): Technology improves. We can now grow white, gem-quality diamonds. Prices are high ($8,000/ct), only 10% cheaper than natural.
- 2020s (The Flood): Mass production begins in India and China. Prices crash from $4,000/ct to $400/ct in 3 years.
Inside a CVD Reactor: Plasma rains carbon down onto seed crystals, layer by atomic layer.
THE ZIZOV VERDICT: WHEN TO BUY WHICH
We are not anti-Lab. We are pro-Information. Here is our advice:
| Goal | Recommendation | Why? |
|---|---|---|
| Engagement Ring | Natural | It represents "forever." You want a stone that holds its value, just like your commitment. It is an heirloom. |
| Fun Fashion Jewelry | Lab-Grown | Want massive diamond studs or a tennis bracelet for travel? Go Lab. It's affordable, and if you lose it on vacation, it's not a financial tragedy. |
| Budget Constraints | Lab-Grown | If you strictly have $2,000 and want a 2-carat look, Lab is the only way. Just understand it is a sunk cost. |
CELEBRITIES & THE RED CARPET SHIFT
You see headlines: "Actress X wears Lab Diamond." Is this a trend?
The PR Reality: Most celebrities on red carpets are paid to wear those diamonds by lab-grown brands (like Swarovski or Pandora). It is a marketing deal, not a personal investment.
The Personal Collection: When celebrities buy for themselves (engagements, private collections), they almost exclusively buy Natural Diamonds. They understand asset value better than anyone. Do not confuse paid sponsorship with personal taste.
THE FUTURE: 2030 PREDICTION
Where is this all going? Based on current data, here is our forecast:
- The Split: The market will bifurcate completely. Lab Diamonds will become "Fashion Jewelry" (sold alongside crystals and silver). Natural Diamonds will become "Luxury Assets" (sold like watches and art).
- The "Costume" Era: Lab diamonds will replace Cubic Zirconia. Why buy CZ when you can buy a Lab Diamond for $50?
- The Heritage Revival: As Lab diamonds become ubiquitous/cheap, Natural Diamonds will actually increase in desirability due to the "Anti-Industrial" sentiment. People crave things that are rare.
FREQUENTLY ASKED QUESTIONS
Can you tell the difference with the naked eye?
No. Not even a jeweler can tell without specialized equipment. They are optically identical. You need a machine that tests for nitrogen (Natural) vs pure carbon (Lab) to know for sure.
Will Lab Diamond prices drop to zero?
They will likely stabilize near the cost of cutting (labor), perhaps $50-$100 per carat, similar to Cubic Zirconia or Synthetic Sapphires. But they will never be "rare."
Does Zizov sell Lab-Grown?
Yes, upon request. We source the highest quality type IIa (purest) lab stones, but we ensure you understand the financial trade-off (zero resale value) before you buy. We do not hide the truth.
Can I insure a Lab diamond?
Yes. But be careful. If you insure it for $2,000 today and lose it in 5 years, the insurance company might only pay out $200 because that is the replacement cost at that time. Premiums are often high relative to the depreciating value.
Are Lab diamonds "fake"?
No. They are real diamonds. They are just not natural diamonds. Think of it like a test-tube baby vs a natural conception. Both are human, but the origin story is different.
Why do some Lab diamonds look blue or gray?
This is due to growth impurities. HPHT stones can look blue (Boron). CVD stones can look brown or gray (Crystal strain). Cheap lab diamonds often have these "off" tints. Zizov only sells "As Grown" (no treatment) or high-quality CVD.
What is "Post-Growth Treatment"?
Many CVD diamonds come out brown. Factories then put them in an HPHT press to turn them white. This is like bleaching a stained shirt. We avoid treated stones as they can be brittle.
Does a Lab diamond fade or get cloudy?
No. It is a diamond. It is the hardest material on earth. It will stay shiny forever, just like a natural diamond. The only thing that fades is its monetary value.
