Lab-Grown Diamonds Surge in Popularity, Both Globally and in Australia

Lab-grown diamonds are transforming the global jewellery market and Australia is no exception. What began as a value-driven alternative is now a major contributor to sales growth for leading jewellers around the world.

Signet Jewelers parent company of retail chains Kay Jewelers, Zales and Jared recently reported 6% same-store sales growth, largely fuelled by strong demand for fashion and bridal jewellery featuring lab-grown diamonds (LGDs). Today, LGDs represent around 40% of Signet’s bridal diamond sales, proving just how quickly consumer preferences are shifting.

This growth is driven by simple customer logic:
Larger stones. Greater brilliance. Lower cost.
Ethically and environmentally responsible.
Exceptional value at key gifting price points.

Retailers are seeing customers choose bigger, higher-quality stones because LGDs allow them to upgrade without increasing their budget a trend transforming both the bridal and fashion jewellery categories.

Lab Grown Workers Strike in “Misunderstanding” on Pay

Hundreds of polishers at Greenlab, recognized as India’s largest lab-grown diamond producer, walked out last Friday (28 November) in a row over wages.

They gathered at the gates of the factory in Surat following reports that their per-carat fee was to be reduced.

But they returned to work a few hours later after management sent out voice messages assuring them there would be no cut.

A Greenlab director described the incident as a “small misunderstanding,” triggered by misinformation during internal discussions on inventory and other business issues.

Bhavesh Tank, vice president of the Diamond Workers’ Union Gujarat, told the Indian Express: “After Diwali, a growth is seen in the demand of the lab grown diamond industry in the domestic and international market.

“The company’s owners should also ensure that the diamond workers, who have been facing financial problems over the last couple of years due to poor market demand, are paid sufficient salaries when the market is in good condition.”

Unions say many workers’ wages have not kept up with living costs, and that both natural and lab-grown units have seen friction over sudden changes in per-carat rates and job losses tied to swings in export demand.

Greenlab operates across the chain, growing rough lab growns, cutting and polishing them, and setting them in finished jewelry for both Indian and export markets.

It famously manufactured the 7.5-carat lab grown diamond that India’s prime minister Narendra Modi gifted to US First Lady Jill Biden in June 2023.

The company sells its polished diamonds through its US subsidiary, Labon, and has a distribution partnership with Florida-based Green Rocks.
