The 'Quiet Engagement' Trend — Coloured Stones and Alternatives in Bridal Jewellery
The 'Quiet Engagement' Trend — Coloured Stones and Alternatives in Bridal Jewellery
A consumer shift away from the diamond solitaire toward sapphires, emeralds, morganite, moissanite, and lab-grown diamonds
The 'quiet engagement' trend is a consumer pattern, documented by trade publications and retailers since the late 2010s, in which engagement-ring buyers increasingly choose coloured-stone centre stones, lab-grown diamonds, or diamond alternatives such as moissanite over the conventional mined-diamond solitaire that dominated the bridal market through the second half of the twentieth century. The shift reflects converging pressures around sustainability, individuality, ethical sourcing, and the cost calculus of bridal spending in a generation facing housing, education, and other competing financial priorities. The trend is meaningful at the volume retail level and is reshaping how the jewellery trade approaches bridal merchandising and product development.
The drivers
Several drivers operate simultaneously. Sustainability and ethical-sourcing concerns, energised by the late-1990s Kimberley Process debates and continuing through the 2010s rise of conflict-mineral disclosure rules, raised consumer awareness that traditional diamond mining carries environmental and labour-rights questions. Lab-grown diamond production, which scaled from approximately 5 per cent of the new-diamond engagement market in 2015 to over 20 per cent in 2023 according to Edahn Golan and Tenoris industry reports, offered an alternative that addressed many of these concerns at substantially lower price points.
Individuality is a second driver. Mid-twentieth-century engagement convention, codified in the De Beers 'A Diamond Is Forever' marketing campaign launched in 1947, treated the round-brilliant solitaire as the default for bridal use. The current generation of buyers, raised on social-media-driven aesthetic differentiation and surrounded by visible examples of celebrity bridal jewellery in non-conventional forms, increasingly views a personalised colour or stone choice as part of the engagement's narrative.
Cost is the third driver. Diamond engagement rings at the conventional one-carat-and-up scale carry meaningful cost in any sector of the market; coloured-stone alternatives at the same physical size carry substantially lower retail prices, and moissanite or lab-grown alternatives can deliver a similar visual scale at a fraction of the natural-diamond cost. For buyers prioritising other financial commitments, the trade-off is increasingly attractive.
The principal categories
Sapphire is the most prominent coloured-stone alternative for engagement use. The 1981 sapphire engagement ring of Lady Diana Spencer (later Princess of Wales), now worn by Catherine, Princess of Wales, is the single most influential reference for the category, and its 2010 reappearance on Catherine's hand triggered a measurable retail surge in sapphire engagement-ring sales. Sapphire's hardness 9 on the Mohs scale, supply consistency, and price spread (from accessible Sri Lankan and Madagascar material through fine Kashmir and unheated Burmese stones) make it well-positioned for the category.
Emerald and ruby occupy smaller but meaningful positions. Emerald carries durability concerns — hardness 7.5 to 8 with significant fracture sensitivity — that warrant careful setting design and client education on care. Ruby, like sapphire a corundum at hardness 9, is mechanically suitable for everyday wear but commercial production at engagement-ring quality is small and prices accordingly high.
Morganite — the pink-to-peach beryl variety — has emerged as a distinct bridal category since approximately 2015, driven by social-media-friendly soft pink colour, Madagascar production volume, and price points well below sapphire and meaningfully below diamond. The variety is well suited to rose-gold and yellow-gold mountings and benefits from a dedicated marketing push by several major bridal-focused jewellery brands.
Lab-grown diamond and moissanite occupy the diamond-alternative segment. Lab-grown diamond is chemically and optically identical to mined diamond and grades on the same GIA scale; the only distinction is origin. Moissanite, silicon carbide, has higher refractive index and dispersion than diamond and shows characteristic high fire and lower visible inclusions; the material is mechanically nearly as durable (hardness 9.25 versus 10) and at a fraction of even lab-grown diamond pricing.
Trade response
Mainstream bridal retailers have expanded coloured-stone, lab-grown, and moissanite inventory to capture the shifting demand, often segregating these into distinct merchandising categories alongside the traditional diamond solitaire range. Independent and bespoke jewellers, including Skyjems, are well-positioned to serve the trend because the bespoke channel allows clients to specify centre stone, mounting, and metal combinations that mass retail cannot match. The conversation that begins with 'I want a non-diamond engagement ring' is now a routine part of bridal client consultations.
In the trade
The quiet-engagement shift is not a complete displacement of the traditional diamond solitaire, which retains the largest single share of the bridal market. Rather, it represents a meaningful diversification of the category, with coloured-stone, lab-grown, and moissanite alternatives growing from negligible market shares in the early 2010s to substantial positions today. For Skyjems and other dealers, the practical implication is that bridal inventory and consultation practice must accommodate the broader range of preferences, and that the educational role of the trade adviser — explaining durability trade-offs, treatment status, sourcing, and care implications across categories — has expanded substantially.
