UK Lab Grown Stones Market Growth & Trends

The UK lab grown stones market size is projected to reach USD 1.76 billion by 2033, growing at a CAGR of 5.0% from 2026 to 2033, according to a report by Grand View Research, Inc. The market expansion is fueled by the increasing consumer trust, competitive pricing compared to mined gemstones, and the rising importance of sustainability and ethical sourcing in luxury purchases. Jewelry retailers across the UK are broadening their collections to meet demand from younger buyers who prioritize transparency and socially responsible brands. Continuous innovation in production processes has strengthened the brilliance, durability, and grading consistency of lab-grown stones, reinforcing their perception as a premium product. As a result, lab-grown stones are rapidly shifting from a niche choice to a mainstream jewelry preference, supported by heightened advertising and promotional campaigns.

In terms of stone type, diamonds lead the UK lab-grown stones market, accounting for over 86% of revenue in 2025 due to their dominant use in engagement jewelry and other high-value pieces. Their identical optical, chemical, and physical properties to natural diamonds-combined with a noticeably lower price point have triggered strong consumer migration toward lab-grown diamond purchases. Colored lab-grown stones, such as rubies, sapphires, and emeralds, are gradually gaining visibility, although their presence remains comparatively limited due to lower retail penetration and consumer familiarity. However, evolving jewelry aesthetics and innovative design themes are expected to accelerate interest in colored alternatives. Demand for fancy-shaped and fancy-colored lab-grown diamonds is also rising as designers explore unconventional and contemporary styles.

The jewelry segment remains the dominant end use category, driven by consistent demand across bridal rings, luxury gifting, and personalized designs. Online jewelers and independent stores are playing a significant role by specializing in custom-made jewelry that leverages the versatility and cost efficiency of lab-grown diamonds. Outside of jewelry, the market is gradually expanding into industrial sectors, as lab-grown diamonds offer high hardness, durability, and outstanding thermal conductivity, making them ideal for applications such as cutting tools, drilling, electronics, and cooling systems. While industry use remains smaller in scale, increasing research in semiconductors, precision engineering, and quantum technologies is expected to strengthen adoption in the years to come.

The consumer inclination toward lab-grown stones in the UK is rooted in value for money, ethical sourcing, and environmental responsibility. Buyers who prefer transparent supply chains and conflict-free gemstones increasingly perceive lab-grown stones as a responsible alternative to mined gemstones. The possibility of obtaining a larger carat size at a lower cost without sacrificing clarity or brilliance has become a major purchasing driver. The flexibility to tailor jewelry through a wide variety of cuts, colors, and clarity grades also aligns well with the rising trend of personalization in engagement and everyday jewelry. Additionally, social media influence, modern fashion preferences, and the growing spending power of younger consumers continue to amplify demand for lab-grown jewelry.

UK Lab Grown Stones Market Report Highlights

The UK lab-grown stones industry is expected to grow at a substantial CAGR of 5.0% from 2026 to 2033. The growth reflects the steadily rising acceptance of lab-grown stones in mainstream jewellery and retail channels across the UK. Growing consumer awareness of sustainability, traceability, and ethical sourcing is influencing purchase decisions, shifting preference toward lab-grown stones rather than mined gemstones. Moreover, advancements in production technology are driving down manufacturing costs, allowing brands to offer high-quality stones at competitive prices while improving margins.
By stone type, diamonds accounted for the largest revenue share of over 86.0% in 2025. Diamonds dominate the stone-type segment because they are the most sought-after gemstone for engagement, wedding, and luxury jewelry applications categories in which the UK has seen a rapid adoption of lab-grown options. Consumers are increasingly drawn to lab-grown diamonds because they offer virtually identical optical brilliance, durability, and hardness to mined diamonds, but at significantly lower price points. Bridal jewellery in particular has shifted toward lab-grown diamonds among younger demographics seeking both value and ethical reassurance.
By production method, the chemical vapor deposition (CVD) segment is anticipated to register the fastest CAGR of 5.7% from 2026 to 2033. The CVD production method is expected to expand fast due to its ability to produce high-clarity, high-quality stones with superior color precision and minimal inclusions, characteristics that are increasingly preferred in fine jewelry markets. CVD technology also offers greater scalability and more consistent yield compared to the HPHT method, enabling manufacturers to produce larger stones with higher transparency at competitive costs. Furthermore, continued innovation in plasma reactor design and gas-flow efficiency is reducing production time and energy consumption, thereby accelerating the industry's adoption of CVD-grown stones.
Novita Diamonds announced in March 2025 the launch of a new line of custom lab-grown diamond engagement rings targeting the UK bridal market. The initiative expands Novita’s sustainable luxury portfolio, offering fully certified CVD and HPHT stones with enhanced clarity and cut options, while promoting ethical sourcing and reduced environmental impact. The launch also includes an online customization platform, enabling consumers to design personalized jewellery pieces with full transparency on stone origin and certification.
Skydiamond revealed in June 2025 the opening of its expanded Sky Lab facility in Gloucestershire, increasing in-house production capacity by 40%. The development supports the company’s mission to create carbon-negative lab-grown diamonds at scale, using atmospheric carbon and renewable energy. The expanded facility enables the handling of larger stones and offers improved colour and clarity ranges, thereby strengthening Skydiamond’s position in the UK fine jewellery market while maintaining its sustainability-first approach.
