How Lab Grown Diamonds Are Reshaping the Jewellery Market
In recent years, lab grown diamonds have surged in popularity, challenging long-held norms in the jewelry industry. These diamonds were once doubted, but now they are part of luxury jewelry collections. You can find them in engagement ring showrooms and high-end fashion collaborations. What was once an alternative is now a preferred choice for many—especially those seeking sustainable and ethically sourced options.
At Tonglin Jewelry, we’ve seen this shift firsthand. As a top jewelry maker in China, we provide natural diamonds and lab-grown options. We tailor our products to meet the needs of a changing market. Here's a closer look at how lab grown diamonds are reshaping the global jewelry landscape—and how your brand can stay ahead.
What Are Lab Grown Diamonds?
Lab-grown diamonds, also known as synthetic or man-made diamonds, are made in a lab. Advanced technology is used to create the same conditions that form natural diamonds in the earth. The result? A diamond that is chemically, physically, and optically identical to its mined counterpart.
The main methods for creating them include:
- HPHT (High Pressure High Temperature)
- CVD (Chemical Vapor Deposition)
Thanks to technological advancements, the quality and availability of lab grown diamonds have significantly improved in the last decade.
Sustainability and Ethical Impact
One of the biggest reasons for the rise of lab grown diamonds is growing concern over the environmental and social costs of traditional mining. Many consumers are choosing more ethical sourcing options. This is due to issues like unfair labor practices, environmental harm, and the carbon footprint of mining.
Lab grown diamonds eliminate many of these issues:
- No harmful mining
- No conflict zones
- Lower water usage
- Lower carbon emissions
At Tonglin Jewelry, we proudly offer lab grown diamonds that meet both sustainability and ethics standards. We also support traceable sourcing, ensuring that our partners and clients can buy with confidence and transparency.
Consumer Demand and Market Growth
As consumers—particularly Millennials and Gen Z—become more socially and environmentally conscious, their preferences are shifting. A growing number of people now ask not just what a product is, but how it was made.
Surveys show that:
- Over 70% of Gen Z buyers are more likely to purchase from brands with sustainable practices.
- Lab grown diamonds now account for over 10% of the global engagement ring market and are expected to grow steadily.
This growing consumer interest is reshaping the market for lab grown diamonds, with retailers expanding their offerings and even luxury brands jumping on board.
Tonglin Jewelry helps clients tap into this trend with customizable engagement rings that feature high-quality lab grown diamonds, made to order and tailored to your brand’s aesthetics.
Lab Grown in Engagement Rings and Luxury Jewelry
The most common use for lab grown diamonds is in engagement rings, where clarity, size, and ethical sourcing matter. Couples today are drawn to the idea of starting their life together with a symbol that aligns with their values.
Key reasons why lab grown diamonds are gaining ground in this space:
- They are visually identical to natural diamonds.
- They typically cost 30–50% less, allowing buyers to get a larger, better-quality diamond for the same budget.
- They meet the growing demand for sustainability and ethical jewelry.
Beyond bridal jewelry, lab grown stones are now being used in:
- Fashion-forward designs
- Fine jewelry collections
- Brand collaborations in the luxury sector
At Tonglin Jewelry, we help brands design lab grown diamond jewelry that fits both minimalist and high-end tastes—from solitaire rings to custom luxury sets.
Optical Properties and Quality
Lab grown diamonds possess the same optical properties as mined diamonds:
- Same brilliance
- Same sparkle
- Same fire and scintillation
Even professional gemologists cannot distinguish between lab and natural diamonds without specialized equipment. Lab grown diamonds are graded the same way as natural stones—by the 4Cs: cut, color, clarity, and carat.
At Tonglin Jewelry, we ensure:
- Precise grading
- Excellent cut quality
- Thorough quality checks at every production stage
Our diamonds are sourced from verified labs and mounted in high-quality settings crafted in-house by our skilled team.
