Today’s diamond market offers more options than ever before — including lab-created diamonds, crafted through cutting-edge technology.
Instead of forming underground over millions of years, these diamonds are grown in high-tech laboratories, offering a more sustainable, accessible, and ethical alternative to natural diamonds — without compromising brilliance or beauty.
At Tang&Co, we believe luxury should be as responsible as it is radiant. Here's everything you need to know about lab-created diamonds.
Are Lab-Created Diamonds Real?
Yes, absolutely.
Lab-created diamonds are chemically, physically, and optically identical to earth-mined diamonds.
Both are made of pure carbon atoms, crystallized in a precise structure — the only difference lies in their origin.
-
Natural diamonds are formed deep within the Earth’s mantle over billions of years.
-
Lab-grown diamonds are created over several weeks in carefully controlled environments using advanced methods that replicate nature.
In brilliance, sparkle, hardness, and lasting beauty — lab-grown diamonds and natural diamonds are virtually indistinguishable.
Lab-Grown Diamonds vs Natural Diamonds
| Lab-Grown Diamond | Natural Diamond | |
|---|---|---|
| Origin | Grown in a lab over weeks or months | Formed naturally over billions of years |
| Rarity | Readily available to meet demand | Rare and harder to source |
| Cost | 60–85% more affordable | Higher cost due to scarcity |
| Environmental Impact | Lower impact, no large-scale mining | Significant land and resource use |
| Brilliance | Identical to natural | Identical to lab-grown |
| Composition | Carbon crystal structure | Carbon crystal structure |
Why Choose Lab-Created Diamonds?
Ethical Origins
Lab-created diamonds offer peace of mind.
They are produced under controlled, transparent conditions, avoiding the environmental harm and ethical concerns associated with traditional mining.
Exceptional Value
Because supply meets demand, lab-grown diamonds avoid the artificial scarcity that drives up natural diamond prices.
This means you can afford larger, more brilliant stones at a fraction of the cost.
Beauty Without Compromise
Lab-created diamonds possess the same sparkle, fire, and durability as natural diamonds — certified and graded to the same standards.
How Are Lab Diamonds Made?
There are two primary methods for growing diamonds in laboratories:
1. High Pressure-High Temperature (HPHT)
This technique simulates the extreme heat and pressure found deep within the Earth’s crust.
A tiny diamond seed is placed inside a chamber where it is exposed to intense conditions, allowing carbon atoms to bond and crystallize around the seed.
2. Chemical Vapor Deposition (CVD)
In this method, a diamond seed is placed in a vacuum chamber filled with carbon-rich gas (like methane).
Using high temperatures, the gas breaks down, and carbon atoms build up on the seed, layer by layer, creating a pure diamond crystal.
Both methods produce genuine diamonds — equally stunning, equally durable.
Frequently Asked Questions
Do Lab-Grown Diamonds Hold Their Value?
Like natural diamonds, lab-grown diamonds typically depreciate after purchase.
However, given that they cost significantly less upfront, they offer a better value for most buyers focused on meaning, beauty, and lasting brilliance rather than investment resale.
Are Lab-Grown Diamonds More Ethical?
Yes.
Lab-grown diamonds eliminate the ethical concerns of traditional mining, require far less land and water, and are increasingly produced using renewable energy sources.
At Tang&Co, we are committed to offering sustainable, conflict-free diamonds — both lab-created and natural — ensuring you can choose with confidence.
Do Lab-Grown Diamonds Get Cloudy?
No, lab-grown diamonds do not get cloudy over time.
Just like their earth-mined counterparts, they have the same chemical composition and durability, maintaining their brilliance indefinitely.
However, everyday exposure to oils, lotions, and dust can temporarily dull their sparkle.
Regular cleaning with a gentle jewelry cleaner or mild soap and warm water will keep your diamond looking as radiant as the day you received it.
Are There Any Downsides to Lab-Grown Diamonds?
While lab-grown diamonds offer remarkable advantages — including affordability, sustainability, and ethical sourcing — they do have some considerations:
-
Resale Value: Lab-grown diamonds typically have lower resale value compared to natural diamonds, due to increased market supply and growing production capabilities.
-
Investment Perspective: If purchasing jewelry as a financial investment is your goal, a mined diamond may retain value slightly better, especially for rare and larger stones.
That said, if you prioritize beauty, sustainability, and exceptional value, lab-created diamonds remain an outstanding choice for engagement rings and fine jewelry.
Conclusion: A Brilliant Blend of Science and Style
Lab-created diamonds offer the same sparkle, hardness, and timeless beauty as natural diamonds — without the billion-year wait or the environmental impact.
They are a more eco-friendly, affordable, and ethical choice, allowing you to enjoy more size, more quality, and more brilliance for less.
At Tang&Co, we are proud to offer a stunning collection of lab-grown diamond engagement rings — crafted to celebrate love stories with meaning, responsibility, and unforgettable sparkle.
