高級ラボグロウンダイヤモンドジュエリーの米国市場：製造方法別、性質別、サイズ別、用途別、地域別、機会、予測、2018年～2032年

米国の高級ラボグロウンダイヤモンドジュエリー市場は、持続可能性、倫理的調達、技術革新により、2025～2032年の予測期間中にCAGR 5.45%を記録し、2024年の15億1,000万米ドルから2032年には23億1,000万米ドルに成長すると予測されています。米国のラボグロウンダイヤモンドジュエリー市場は、持続可能性、手頃な価格、技術革新、消費者の価値観の変化といった要因に後押しされ、著しい成長を遂げています。

ラボグロウンダイヤモンドにとって、手頃な価格であることは大きな要因の一つです。一般的に、ラボグロウンダイヤモンドは天然ダイヤモンドより30～40％安く、そのため幅広い消費者層を惹きつけています。したがって、信用に詳しく、かつ高品質の製品を求めるミレニアル世代やZ世代を中心とする若い世代にとって、価格の魅力は非常に魅力的です。もうひとつの要因は、ラボグロウンダイヤモンドの倫理的で持続可能な側面です。これらのダイヤモンドは、採掘を伴わない管理された環境で入手することで、児童労働や環境破壊など多くの問題において、採掘製品に代わる実行可能な選択肢を提供します。このような懸念は、特に社会的意識の高い消費者にとって好都合であり、若い世代は、環境に優しく、倫理的にカウントされた購入に傾倒している、ここでの主要なプレーヤーです。その上、ラボグロウンダイヤモンドは、天然ダイヤモンドの採掘に比べ、炭素排出量と水消費量が少ないという、環境面での利点も保証しています。技術の進歩も市場開発の主な原動力となります。化学気相成長法（CVD）と高圧高温法（HPHT）という製造技術の進歩により、ラボグロウンダイヤモンドの品質が向上し、価格が引き下げられました。ミレニアル世代とZ世代に代表される消費者の嗜好の変化も、倫理的な目的、環境の持続可能性、手頃な価格でラボグロウンダイヤモンドを好むようになっています。この変化の中で、体験的で意識的な消費への文化的シフトがあり、ラボグロウンダイヤモンドをアピールする世代を補完しています。ブランドと消費者がラボグロウンダイヤモンドの利点を採用すればするほど、その急成長はより強固なものとなり、いつの日かこのダイヤモンドが、主流のラグジュアリージュエリーの代替品として同じように展示されるようになることを意味するだけです。

例えば、ラボグロウンダイヤモンドを専門とする大手オンライン小売業者であるGrown Brillianceは、カリフォルニア州ロサンゼルスのMelrose Placeに最新の店舗をオープンし、実店舗の存在を拡大しました。さらに2024年7月、Grown Brillianceは、ピンクとブルーのラボグロウンダイヤモンドを使用した初のMelrose collectionを発表しました。

United States luxury lab grown diamond jewelry market is projected to witness a CAGR of 5.45% during the forecast period 2025-2032, growing from USD 1.51 billion in 2024 to USD 2.31 billion in 2032, owing to sustainability, ethical sourcing, and technological innovation. The lab-grown diamond jewelry market in the United States is seeing remarkable growth, fueled by factors such as sustainability, affordability, technological innovation, and shifting consumer values.

Affordability is one major driver for lab-grown diamonds. Generally, lab-grown diamonds are 30-40% cheaper than natural diamonds, thus attracting a wider consumer base; therefore, the price appeal is quite attractive to the younger generation, riddled with millennials and gen Z, who are credit-savvy yet after high-quality products. Another factor is the ethical and sustainable angle of lab-grown diamonds. These diamonds provide a viable alternative to mined products in many issues, including child labor and environmental destruction, by acquiring them in a controlled environment that does not involve mining. Such concerns are especially favorable for socially conscious consumers, with the younger generation being the key players here who are inclined towards eco-friendly and ethically counting purchases. Besides, lab-grown diamonds assure one extra environmental benefit: lower carbon emissions and less water consumption in comparison with natural diamond mining. Technological advancement also serves as the chief engine for market development. Advances made in terms of the production technologies, chemical vapor deposition (CVD) and high pressure high temperature (HPHT), have enhanced quality and reduced the price of lab-grown diamonds, thus making them even more competitive in the luxury market. This combination driving demand includes shifting consumer preferences typified by millennials and gen Z increasingly favoring lab-grown diamonds for ethical purposes, environmental sustainability, and affordability. Amid this change, there is a cultural shift toward experiential and conscious consumption, which has complemented the laboratory-grown diamond appeal generation. The more that brands and consumers adopt lab-grown diamond benefits, the more solidified its ramping growth will be, which will only mean that one day this diamond will stand as an equally displayed alternative in mainstream luxury jewelry.

For instance, Grown Brilliance, a leading online retailer specializing in lab-grown diamonds, has expanded its physical retail presence with the opening of its newest store location on Melrose Place in Los Angeles, California. Further in July 2024, Grown Brilliance launched the Melrose collection, its first offering to feature pink and blue lab-grown diamonds.

Increasing Awareness Driving the United States Luxury Lab Grown Diamond Jewelry Market

The United States luxury lab-grown diamond jewelry market is experiencing significant growth, driven by increasing awareness among consumers about the benefits of lab-grown diamonds. Gradually, consumers have been made aware of how the chemical, physical, and optical conditions have continued to be the same as in natural diamonds, through extensive marketing campaigns, social media, and digital platforms. This factor is further enhanced by transparency in the supply chain, where brands are adopting technologies like blockchain to come forward with their clear origin and process for manufacture as well as building trust and confidence in using these resources. The other most significant factors boosting the intake of lab-grown diamonds are sustainability and ethical attraction already made by their existence due to increasing concerns about the eco-friendliness of diamond mining and, of course, blood diamonds. They are seen as conflict-free, feasible alternatives that are endorsed by the young socially aware consumer base like millennials and gen Z, looking for greener and ethical consumption. Laboratory-grown diamonds seem to resonate very well with the definition of such customers in this demographic. Further, lab-grown diamonds are being embraced by the youngest segments of millennials for their ingenuity, originality, and value. Celebrity endorsements and direct promotions through social platforms are also influencing this market, where an individual celebrity or social media influencer advocates use and consumption of lab-grown diamonds as a luxury. Lastly, with the rise in e-commerce and omnichannel tickle strategies, the consumption of this product has even become more comfortable, as it can be available to a wider range without limiting the shopping experience.

In May 2024, Pandora Jewelry LLC, which is into lab grown diamond jewelry business, announced impressive sales in the first quarter. The Brand experienced an 18% increase in annual sales and anticipated growth at a rate of 8% to 10%.

Technological Advancements Driving the United States Luxury Lab Grown Diamond Jewelry Market

Continuous innovations in technology are major drivers of growth in the United States luxury lab-grown diamond jewelry market and make a major revolution in the science of creating, marketing, and consuming diamonds. Technological innovations in diamond-growing have reduced the significance of quality, colorless diamonds with less impurity to become nearly indistinguishable from natural ones; they have made available not only more significant stones but also the opportunity for a richer, loftier buying experience. Hybridization combining CVD and HPHT methods extends the possible limits of quality of size even further, thus making lab-grown diamonds much more desirable to luxury customers. Moreover, technologies such as blockchain and laser inscription also offer a unique level of transparency and traceability that allows consumers to check the origin and authenticity of their diamonds, thereby enhancing trust and confidence in the product. In the future, continuous R&D and cooperation between brands, universities, and research institutions will serve to innovate further in terms of quality, size, and color range of lab-grown diamonds. These advances, while going a long way towards broadening the appeal of lab-grown diamonds, will also include them as a luxury proposition concerning sustainability. What will make lab-grown diamonds popular is technology, evolving the market and bringing diamonds to the forefront as the gold standard in preference of the consumer base valuing innovation, transparency, and sustainability.

For instance, in February 2025, De Beers plc introduced its groundbreaking retail diamond verification device, DiamondProof, which is now available in select retail stores for the first time. This device allows consumers to see just how quickly it can differentiate between natural diamonds and non-natural options, such as laboratory-grown diamonds (LGDs) and diamond simulants. It serves as a valuable tool for retailers to educate their customers about the distinctions between natural diamonds and other alternatives.

Chemical Vapor Deposition (CVD) is Anticipated to Propel the Growth of the Market

Chemical vapor deposition (CVD) is expected to provide an impetus toward the development of diamond jewelry in general and that of lab-grown diamonds in the United States in particular. The state-of-the-art manufacturing process provides environmentally sustainable and ethically sourced diamonds, meeting the expectations of modern luxury consumers. CVD produces diamonds with high clarity, color, and purity that are usually indistinguishable from natural diamonds and thus very coveted in high-end jewelry. This technology manufactures diamonds Type IIa, the purest diamond class, meaning no or little impurity exists and those that are the best fit for luxury. Further, larger diamonds, up to 10 carats or more, of reassuringly high clarity and color grades led to the fast development for bigger and luxury objects of desire. The scalability at low cost of CVD would rank as one of its furthermore substantial advantages. CVD is indeed energy-efficient and resource-efficient compared to diamond mining and other lab-grown processes such as HPHT, which translates to a comparatively lower cost of production.

For instance, domestic companies such as CVD Diamond Inc., are manufacturers and wholesale distributors of high-quality, type IIA CVD lab-grown diamonds for the US jewelry industry.

Future Market Scenario (2025 - 2032F)

As environmental and ethical concerns become more prominent, consumers will increasingly opt for lab-grown diamonds as a sustainable and conflict-free alternative to mined diamonds.

The demand for unique, personalized jewelry designs will grow, with lab-grown diamonds offering greater flexibility for customization due to their affordability and availability.

Innovations in diamond-growing technologies, such as chemical vapor deposition (CVD) and high pressure high temperature (HPHT), will enable the production of larger, higher-quality diamonds with fewer imperfections.

Increased marketing efforts and celebrity endorsements are likely to boost consumer acceptance.
