Lab-grown diamonds and future materials: when rarity stops setting the price

When “rarity” is no longer the primary source of value — a research-based marketing analysis.

Introduction

For more than a century, diamonds have been positioned as the ultimate symbols of love, wealth, and achievement. Their natural rarity, combined with supply control, marketing, and brand communication, has established natural diamonds as some of the world’s most economically and emotionally valuable gemstones.

Over the past two decades, however, scientific progress has fundamentally altered the assumptions on which the diamond industry was built. Technology can now produce diamonds in controlled facilities with the same chemical composition, crystal structure, and physical properties as natural diamonds.

The emergence of lab-grown diamonds has done more than provide consumers with an additional choice. It has raised fundamental questions about the entire concept of diamond value. If a diamond created in a laboratory possesses essentially the same properties as a natural diamond, why should consumers pay a substantially higher price for the latter?

This question affects more than the diamond industry alone. It reflects a broader transition within the luxury market — from an era in which value was determined primarily by the “rarity of materials” to one in which value is increasingly created through “narrative, trust, and consumer experience.”

3.1 What is a lab-grown diamond?

A lab-grown diamond is a diamond produced under controlled conditions in a laboratory or manufacturing facility. The production process recreates the natural conditions under which diamonds form deep within the Earth, compressing a geological process that normally takes hundreds of millions or even billions of years into a period of only several weeks.

Although these stones are sometimes described as “synthetic diamonds,” they are not artificial substitutes or diamond simulants such as cubic zirconia or moissanite.

Lab-grown diamonds consist of pure carbon arranged in the same crystal structure as natural diamonds. They possess a hardness of 10 on the Mohs scale and display optical properties, thermal conductivity, and durability that are almost indistinguishable from those of natural diamonds.

For this reason, distinguishing a natural diamond from a lab-grown diamond generally requires scientific instruments and specialist gemological laboratories. Visual inspection with the unaided eye is not sufficient.

3.2 The technologies transforming the diamond industry

Contemporary lab-grown diamond production relies primarily on two technological processes.

High Pressure High Temperature — HPHT

The High Pressure High Temperature, or HPHT, process recreates the conditions found deep within the Earth. It uses extremely high pressure and temperature to encourage carbon to crystallize into diamond.

This technology has been under development since the middle of the twentieth century and is now used to produce diamonds for both industrial and jewelry applications.

Chemical Vapor Deposition — CVD

Chemical Vapor Deposition, or CVD, creates diamond crystals by depositing carbon atoms from gas inside a controlled vacuum chamber. This process allows manufacturers to regulate the quality, size, and purity of the developing crystal with considerable precision.

CVD technology has become increasingly prominent because it can produce high-quality diamonds at declining costs and is well suited to the manufacture of diamonds for premium jewelry.

Advances in both HPHT and CVD technologies have rapidly reduced production costs. As a result, the retail prices of lab-grown diamonds have continued to decline in recent years.

3.3 The changing concept of “value”

Historically, the value of diamonds was built primarily upon the concept of scarcity. Discovering diamond deposits required extensive geological exploration, substantial investment, and complex mining operations. These conditions limited the supply of natural diamonds and contributed to their high market value.

When technology makes it possible to produce diamonds according to demand, however, the concept of scarcity begins to be questioned.

From an economic perspective, reduced scarcity generally influences price. From a marketing perspective, however, the more profound change concerns the “reason for purchasing.”

Some consumers continue to choose natural diamonds because they value them as products of nature, formed over immense periods of geological time. Others regard lab-grown diamonds as offering comparable beauty and physical properties at a more accessible price.

Competition is therefore no longer based solely on physical characteristics. It has become a contest between “narrative value” and “functional value.”

Natural diamonds may derive value from geological history, rarity, symbolism, and intergenerational continuity. Lab-grown diamonds may derive value from technological innovation, accessibility, design flexibility, and price efficiency.

The two categories therefore represent not only different materials or production methods, but also different systems through which consumers interpret value.

3.4 The behavior of younger consumers

Consumer studies conducted in several countries indicate that Millennials and Generation Z often evaluate products differently from previous generations.

When purchasing jewelry, consumers in these groups frequently consider several factors simultaneously, including:

• Value for money
• Environmental impact
• Transparency of origin
• Designs that express personal identity
• Opportunities for customization

Lab-grown diamonds have therefore attracted attention as an alternative for certain consumer groups, particularly those who prioritize design and affordability over the natural rarity of the material.

The market, however, is not moving in a single direction. Many consumers continue to value natural diamonds as assets connected to history, nature, and inheritance between generations.

This development indicates that the diamond industry is evolving from “one market” into “multiple markets,” each shaped by different purchasing motivations.

One segment may seek natural rarity and geological authenticity. Another may prioritize accessible luxury and technological innovation. A third may place greater emphasis on design, personalization, or the emotional meaning of the finished piece.

Understanding these distinctions is becoming increasingly important for jewelry brands, retailers, and designers.

3.5 Future materials and emerging innovations

The transformation of the jewelry industry is not limited to lab-grown diamonds.

Jewelry manufacturers and designers are experimenting with a growing range of materials and technologies, including:

• Lab-grown gemstones
• Recycled gold
• Metal alloys designed to reduce environmental impact
• Bio-based materials
• Lightweight composite materials
• Manufacturing through three-dimensional printing, or 3D printing

These technologies can reduce design limitations, minimize production waste, and enable manufacturers to create products that respond simultaneously to demands for sustainability and personalization.

Three-dimensional printing, for example, allows designers to produce highly complex forms that may be difficult to achieve through conventional manufacturing. It can also facilitate prototyping, made-to-order production, and the efficient use of materials.

Lab-grown gemstones can provide greater consistency in color and quality, while recycled metals allow valuable materials to remain within the production cycle rather than requiring continual extraction of new resources.

Future materials therefore have the potential to transform not only the appearance of jewelry but also the systems through which it is designed, manufactured, distributed, repaired, and reused.

3.6 Effects on the jewelry industry

The growth of lab-grown diamonds is forcing the jewelry industry to revise its strategies in several areas.

Natural-diamond producers are placing greater emphasis on communicating provenance, rarity, geological origin, and cultural value. Lab-grown diamond producers, by contrast, tend to emphasize innovation, transparency, affordability, and technological achievement.

Many retailers have adapted their presentation strategies by clearly separating natural-diamond and lab-grown-diamond collections. They also provide information intended to help consumers make decisions according to their personal preferences, intended use, and budget.

At the same time, jewelry manufacturers are expanding their bespoke and personalization services in order to create value beyond the materials themselves.

This shift is strategically important. When two products possess similar visual and physical characteristics, differentiation must increasingly be created through other dimensions, such as:

• Design
• Craftsmanship
• Brand narrative
• Customer service
• Personalization
• Certification and disclosure
• The overall purchasing experience

The finished piece of jewelry must therefore communicate more than the technical specifications of the stone it contains.

3.7 Marketing opportunities for Thailand

Thailand possesses a strong advantage as a regional center for jewelry manufacturing and design.

The transformation of the diamond market creates several new opportunities for Thai businesses, including:

• Designing contemporary jewelry with lab-grown diamonds for younger consumers
• Creating collections that combine natural and lab-grown diamonds according to their intended purposes
• Adding value through craftsmanship and design rather than competing solely on material prices
• Developing bespoke jewelry services
• Using digital technologies to communicate information about materials and production processes

Thai manufacturers may also use their established capabilities in gemstone cutting, setting, metalwork, and small-scale production to serve increasingly fragmented consumer markets.

For example, natural diamonds may be positioned within heirloom, ceremonial, or high-luxury collections, while lab-grown diamonds may be used in contemporary fashion, personalized jewelry, or design-led pieces intended for everyday wear.

Collections may also combine different categories of stones according to symbolic or functional purposes. A central natural diamond, for instance, may be accompanied by lab-grown accent stones, allowing designers to balance narrative value, visual impact, and price accessibility.

In the long term, the ability to create distinctive designs and meaningful customer experiences will become a more powerful source of differentiation than reliance on any single category of material.

3.8 Strategic analysis

The emergence of lab-grown diamonds demonstrates that technology can significantly reduce the limitations created by material scarcity. It cannot, however, entirely replace the emotional value, narratives, and meanings that consumers associate with a product.

For marketers, the principal challenge is therefore not to determine which type of diamond is inherently “better.” The more important task is to understand what each consumer segment values.

Some consumers prioritize history and rarity. Others prioritize innovation and value for money. Another group places greater importance on design, personalization, and emotional meaning.

The future success of jewelry brands will therefore depend on their ability to present forms of value that correspond with the motivations of each consumer group, rather than competing solely through the physical properties of materials.

A brand selling natural diamonds may emphasize geological time, provenance, rarity, inheritance, and enduring symbolism. A brand offering lab-grown diamonds may emphasize technology, creative freedom, accessibility, and contemporary values. A design-focused brand may use either material while concentrating on craftsmanship, personalization, and storytelling.

The strategic question is no longer simply: “Which diamond should the brand sell?” It is increasingly: “What meaning does the brand wish to create, and for which consumer?”

Conclusion

Lab-grown diamonds do not represent the end of natural diamonds. Rather, they mark the beginning of a new era in which consumers have more choices and the definition of “value” has become more diverse.

The jewelry industry is moving away from an exclusive emphasis on the scarcity of natural resources and toward the creation of value through innovation, transparency, design, craftsmanship, and consumer experience.

For Thai jewelry businesses, this transformation should be viewed as an opportunity to progress from contract manufacturers, or Original Equipment Manufacturers — OEMs, into brand creators capable of integrating technology, craftsmanship, and cultural narratives.

Such a transition would allow Thai businesses to compete not only through production capability but also through intellectual property, design identity, customer relationships, and brand meaning.

By combining contemporary materials with skilled craftsmanship and culturally informed storytelling, Thai jewelry brands can create distinctive and sustainable positions within the global market.

Direction for Chapter 4

The next chapter, “The Revival of Craftsmanship,” will examine why consumers are placing renewed value on handmade objects in an era dominated by automation, artificial intelligence, and mass production. It will also explore the role of craftsmanship in creating brand value, establishing market differentiation, and preserving cultural heritage within the contemporary jewelry industry.
