Consumer Demand and Fashion Trends in Gemstones: What’s Driving the Market

When Princess Diana chose a 12-carat oval blue sapphire engagement ring in 1981, sapphire engagement ring sales surged across the British market within weeks. When Kate Middleton received the same ring in 2010, the effect was global and sustained. When celebrities began wearing large oval-cut diamonds in the 2010s, the oval shape went from niche to dominant in the engagement ring market within two years. Gemstone demand is not purely rational — it is powerfully shaped by fashion, celebrity, cultural trends, and the self-reinforcing dynamics of social visibility. Understanding these forces is not peripheral knowledge for jewellery professionals. It is the market intelligence that determines which stones to stock, what shapes to feature, and how to interpret the questions customers walk in with.

This article examines the forces shaping consumer gemstone demand, traces significant trend cycles in the modern era, and provides a framework for anticipating and responding to market shifts.

The Forces Driving Gemstone Trends

Celebrity and Royal Influence

No force in recent gem market history has matched the direct demand impact of high-visibility celebrity and royal jewellery choices. The mechanisms are immediate and measurable: a celebrity engagement ring photographed and published globally creates search spikes, retailer enquiries, and competitive buying from consumers who want to be associated with the same aesthetic. The Diana/Kate sapphire effect is the most cited example, but similar effects have been documented for every major royal and celebrity engagement in the social media era.

The business implication is clear: jewellery professionals who follow high-profile engagements and red carpet jewellery choices and are prepared to serve the resulting demand will capture customers who arrive with a specific, media-influenced vision. Being knowledgeable about the piece that inspired the customer’s interest — even if your version is very different in price — is a powerful connection point.

Social Media and Visual Culture

Instagram, Pinterest, and TikTok have transformed the dynamics of jewellery trend adoption. A style that previously might take years to diffuse from fashion leaders to mainstream consumers now spreads in weeks. Influencer accounts dedicated to engagement rings, fine jewellery, and gem collecting have audiences of millions who actively seek and share jewellery inspiration. The algorithmic amplification of visually striking content means that unusual shapes, exceptional colour, and distinctive design elements get disproportionate exposure.

For gem trends specifically, social media has been a significant driver of the “coloured stone engagement ring” movement. Images of pink sapphires, morganite, alexandrite, and fancy-coloured diamonds circulate widely, normalising non-traditional choices and expanding the consideration set for customers who previously assumed they wanted a white diamond. This is a structural shift, not a fad.

Generational Values

Millennial and Gen Z consumers bring different priorities to jewellery purchasing than previous generations. Environmental and ethical sourcing credentials are increasingly important. The “lab-grown vs natural” decision is genuinely contested for these consumers in a way it was not for older buyers. Individual expression over tradition — choosing a stone that reflects personal meaning rather than following convention — is a consistent theme. Coloured birthstones, alternative gem species, and custom or bespoke pieces appeal to these values.

Asian Market Dynamics

The growth of affluent consumer classes in China, India, Southeast Asia, and the broader Asia-Pacific region has fundamentally reshaped global gem demand. Culturally, jade (particularly jadeite), ruby, and natural pearl carry enormous significance in Chinese tradition. The rapid growth of Chinese collector and consumer spending has driven demand for these categories to levels that have permanently altered market pricing. Indian consumer demand for coloured gemstones — particularly ruby, emerald, and traditional diamond formats — represents a massive and growing market that shapes global supply.

Significant Trend Cycles in the Modern Era

The Rise of Coloured Stones in Engagement Rings

The traditional white diamond solitaire dominated Western engagement ring markets for most of the 20th century, driven by De Beers’s “A Diamond is Forever” campaign and the cultural normalisation of diamond engagement rings. The 2010s saw a significant shift: coloured stone engagement rings — led by the Kate Middleton sapphire effect and amplified by social media — moved from 5–10% of the market to 20–30% in some retail segments, with further growth continuing.

The Shape Revolution

Engagement ring shape preferences have cycled dramatically. The round brilliant dominated from the 1970s through the 2000s. The cushion cut surged in the early 2010s. The oval shape dominated the mid-to-late 2010s and remains extremely popular. Pear and marquise shapes experienced revivals. Each cycle shifts demand for rough crystals of different shapes, creating temporary supply-demand imbalances that affect cutting centre economics.

Morganite and Pastel Gems

The 2010s saw an extraordinary rise in demand for morganite — the pink-peach variety of beryl — as an engagement ring centre stone. Driven by its soft colour, affordability relative to diamond, and social media appeal, morganite went from near-obscurity to mainstream in the space of three to four years. The morganite trend introduced a generation of buyers to the beryl family and demonstrated how quickly social media can move an entire gem category.

Responding to Trends as a Retail Professional

The professional response to gem market trends involves three elements:

Awareness: follow influencer jewellery accounts, celebrity engagement news, and trade publications to stay current on what is generating excitement

Preparation: identify which trending styles you can credibly offer and stock accordingly, even if only in a limited way

Expertise: when a customer arrives inspired by a trend, be the person who can explain it — the gem species, the quality factors, how to choose well within it
