This report provides an in-depth analysis of consumer preferences and purchasing trends within the natural diamond jewellery market.
One of the key highlights of the report is the detailed breakdown of the 4Cs—Cut, Colour, Clarity, and Carat weight—revealing the most sought-after features among buyers. It explores the most popular diamond shapes, colour trends, and clarity grades, giving a comprehensive overview of consumer preferences in 2024.
Round diamonds continue to reign supreme, making up 82% of centre stones in natural diamond jewellery. However, the report notes a rising interest in fancy shapes, particularly elongated silhouettes such as Oval diamonds. These shapes offer a distinct aesthetic and enhance the elegance of the wearer’s hand, allowing consumers to showcase their individuality.
VS-clarity diamonds are becoming increasingly popular, while SI (Slightly Included) diamonds remain a long-time favourite among American consumers. This shift suggests a growing preference for higher clarity grades as buyers look for a balance between visual appeal and value.
Consumers are gradually moving beyond the traditional 1-carat benchmark, opting for larger centre stones. This trend reflects an increasing willingness to invest in standout pieces that make a bold statement.
Bridal diamond jewellery accounted for 33% of all natural diamond jewellery sales in 2024, with brides and brides-to-be prioritising heirloom-quality pieces to mark their special day. The report delves into the most popular engagement ring sizes and styles, alongside the impact of celebrity influence on bridal jewellery trends.
Despite evolving trends, natural diamonds remain highly valued for their timeless appeal and emotional significance. They continue to be a preferred choice for commemorating life’s milestones, reinforcing their status as meaningful gifts.
The report also examines seasonal buying patterns, price trends since 2020, and the rise of self-purchasing consumers. Notably, the average price of diamond jewellery purchased for Valentine’s Day increased by 2.7% to $2,066 (£1,638), with diamond rings emerging as the top choice for this occasion.
