U.S. couples spent 5% less on engagement rings in 2024 : The Knot

In recent years, the engagement ring market has witnessed significant changes, particularly in consumer spending and gemstone preferences. According to a report by The Knot, U.S. couples spent approximately 5% less on engagement rings in 2024 compared to the previous year. The average cost of an engagement ring fell from $5,500 in 2023 to $5,200 in 2024, marking a 10% decline from 2022 and a 13% decrease from 2021. This trend aligns with the increasing preference for lab-grown diamond center stones, which, for the first time, accounted for more than half of all engagement rings purchased. The shift towards synthetic diamonds has surged by 40% since 2019, contributing significantly to the downward trend in overall spending on engagement rings.
The rise in demand for lab-grown diamonds is not only reducing costs but also influencing the size of center stones. While the average cost of a natural diamond engagement ring remains at $7,600, couples who opt for lab-grown alternatives tend to select larger stones. In 2024, the average engagement ring center stone measured 1.7 carats, an increase from the 1.5-carat average in 2021. This shift suggests that couples are prioritizing carat size while seeking more affordable alternatives to mined diamonds. Additionally, shape and metal preferences have remained relatively stable, with round and oval cuts being the most popular, and white and yellow gold accounting for over 70% of engagement ring settings. Notably, yellow gold has increased in popularity by 5% year-over-year, while white gold has declined by 3%.
Beyond gemstone and metal choices, setting styles are also evolving. Prong settings continue to dominate, with 35% of respondents selecting this classic option. However, the hidden halo setting—a cluster of diamonds encircling the base of the center stone—has gained traction, capturing 18% of the market and surpassing the traditional halo setting, which saw a decline to 13%. This trend reflects a shift in aesthetic preferences among modern couples who seek a balance between timeless elegance and contemporary design. Moreover, the engagement ring purchasing process has become more meticulous. Over half of proposers spent between one and four months researching and selecting a ring, with a quarter taking even longer. The increase in shopping duration correlates with a rise in the number of jewelers visited. On average, proposers explored five stores in 2024, compared to just two in 2022 and 2023, underscoring the importance of in-person evaluation before making a purchase.
The engagement ring industry continues to adapt to evolving consumer behavior, as financial considerations, ethical concerns, and aesthetic trends shape purchasing decisions. With lab-grown diamonds offering an affordable yet visually identical alternative to natural diamonds, the shift in spending and preferences is likely to persist. As couples become more discerning and invested in the selection process, the future of the engagement ring market may see further innovations and adjustments to meet the needs of modern consumers.

Fancy Colour Diamond prices soar 205% since 2005 amid growing luxury demand, Says NDC
Prices for fancy colour diamonds have surged by an impressive 205% since 2005, according to a new report by the Natural Diamond Council (NDC), in collaboration with Choron Group and the Fancy Color Research Foundation (FCRF).

These exceptionally rare gems—known for their vivid hues of pink, blue, yellow, green, and red—now rank among the most sought-after and resilient assets in the natural diamond market.
Representing just 0.01% of all natural diamonds mined, fancy colour diamonds have captured growing interest from collectors, luxury jewellery houses, and investors. Data from the FCRF shows that pink diamonds have skyrocketed in value by nearly 394% over the past two decades, while blue diamonds have risen by over 240%, and yellow diamonds by almost 50%. Overall, fancy colour diamonds have posted a compound annual growth rate (CAGR) of 5.7%.
Once considered a niche category, these vibrant stones now feature prominently in high-profile auctions and luxury jewellery collections. Recent standout sales include the 10.03-carat Mediterranean Blue diamond, which fetched $21.4 million at Sotheby’s Geneva—more than $2.1 million per carat—and the historic 10.38-carat Marie-Thérèse Pink, sold at Christie’s New York for nearly $14 million.
Auction houses are increasingly showcasing a broader selection of fancy colour diamonds, driven by both aesthetic allure and their perceived long-term investment value, especially in today’s uncertain economic climate.
Supply remains extremely limited, with fancy colour diamonds mined in only a few regions globally—such as Canada, Botswana, South Africa, Sierra Leone, and the now-closed Argyle mine in Australia—adding to their exclusivity.
As luxury consumers place greater emphasis on rarity, provenance, and artistry, fancy colour diamonds are expected to maintain their prominence. With upcoming events like Paris Haute Couture Week, these extraordinary gems are poised to continue leading trends in high jewellery, elite auctions, and alternative investments.

ALROSA’s Severalmaz ramps up output as Karpinsky-2 diamond pipe enters development
Russian diamond giant ALROSA has begun full-scale development of the Karpinsky-2 kimberlite pipe at the M.V. Lomonosov diamond field in the Arkhangelsk region, marking a major step forward for its local subsidiary, Severalmaz. Karpinsky-2 becomes the third active pipe at the site, alongside the existing Arkhangelsk and Karpinsky-1 operations.

Karpinsky-2 holds more than 40 million tonnes of diamond-bearing ore and was first evaluated in 2018 through pilot mining operations, which confirmed its commercial viability. Preparatory work for full development began earlier this year, and the project officially moved into the design phase during a recent visit by ALROSA CEO Pavel Marinychev.
Marinychev, who personally launched the design stage, also assessed Severalmaz’s performance for 2025 during his visit. In the first five months of the year, the company surpassed its ore extraction targets and improved operational efficiency, resulting in a 9.4% increase in ore processing. These gains translated into the production of more than 1.2 million carats of rough diamonds.
The CEO also reviewed progress on a new water recycling system at the Lomonosov processing plant and emphasized the importance of completing a gym facility for workers at the shift village by year-end, highlighting the company’s focus on both sustainability and employee well-being.
“I am sure that the work of the Severalmaz team will drive the enterprise’s continued growth. We remain committed to providing safe working conditions and contributing to the development of the Arkhangelsk region,” Marinychev stated.
ALROSA, which produces about 30% of the world’s diamonds and 90% of Russia’s output, reported production of 33 million carats in 2024. The company’s proven reserves exceed 1 billion carats, solidifying its position as the global leader in diamond mining.
