(And You Might Too)
At Mercery, we’ve spent nearly 20 years crafting beautiful, high-quality jewelry. Along the way, we’ve seen how the industry has evolved—and how consumer values are shifting. Today, people want more than sparkle. They want transparency, sustainability, and ethical choices behind every stone.
That’s why we’ve integrated lab-grown gemstones into our material portfolio.
Colored gemstones are mined through a mix of large-scale, small-scale, and artisanal operations across nearly 50 countries. Along the way, these stones often change hands multiple times before reaching the end consumer. With such a complex and sometimes unregulated supply chain, it can be difficult to trace their origins or verify that they were sourced and produced responsibly.
With lab-grown gemstones, we eliminate the guesswork. There’s no need for destructive mining, no harm to ecosystems, no displaced communities. Just high-quality gemstones, grown in a lab under controlled conditions—and with a much lighter environmental footprint.
Our lab-grown gemstones are crafted to match the look and feel of natural stones. We start from the source, choosing high-quality raw gemstones, then cutting and shaping them in-house according to your exact needs. Whether you want classic faceted gems or smooth cabochons, we tailor each stone to bring out its unique charm.
Here’s what makes them truly stand out:
From deep emerald greens to soft pastel pinks, lab-grown gemstones come in a wide spectrum of bold and rich colors. Since they’re grown in a controlled environment, we can achieve color precision that’s hard to find in nature—making them perfect for custom designs or matching brand palettes.
Grown in a precise, controlled setting, lab-grown gemstones naturally develop with fewer internal flaws or visible marks. This leads to outstanding clarity—giving each stone a cleaner, brighter look that catches the light beautifully and elevates its overall brilliance.
Cutting gemstones isn’t just a technical process—it’s an art. At Mercery, our master cutters bring years of training and craftsmanship to every stone. Following our strict in-house standards, each lab-grown gem is meticulously hand-cut to bring out its best color, sparkle, and shape. From proportion and symmetry to the final polish, every detail is carefully refined to ensure maximum brilliance.
One of the biggest perks? More value for your money.
Lab-grown gemstones look and perform just like mined stones—but without the hefty price tag. That means your customers can enjoy luxury looks, sustainably sourced, at a friendlier price point.
We believe in making beautiful things, responsibly. Lab-grown gemstones allow us to offer you a reliable, ethical, and high-performing alternative that doesn’t compromise on beauty—or your brand values.

Harnessing the Sun for Sustainable Craftsmanship
Today’s consumers demand transparency and environmental responsibility from the brands they support. By outfitting our Shanwei, China factory with a 152-panel, 89.68 kWp rooftop solar array, we’ve created a fully traceable, zero-carbon supply chain that delivers both a powerful sustainability narrative and tangible cost savings for your brand.
Covering 400 m² of rooftop and generating approximately 104,500 kWh annually (about 600 kWh per day), our system leverages Shanwei’s 1,420 peak-sun hours (Meteonorm) to meet the bulk of our production energy needs. This on-site power supply breaks our dependence on volatile grid rates and ensures consistent, competitively priced electricity year-round.
Transforming Sunshine into Savings
By producing our own electricity, we stabilize per-unit energy costs and improve operating margins. Compared to conventional coal-fired generation, our solar output displaces roughly 37.6 tonnes of standard coal per year—translating into:
These emission reductions occur with zero on-site pollution, delivering real environmental impact alongside economic benefits.
Creating Shared Value
All clean energy produced powers our daily operations; any surplus is sold back to the grid at preferential rates and redirected to underserved schools, clinics, and community centers. Each kilowatt-hour you source from us can therefore be translated into verifiable carbon credits—strengthening both your sustainability reporting and your social impact.
Strategic Benefits for Your Brand
