The natural diamond market in April 2025 revealed significant pricing trends across clarity and color categories, shaped by supply chain shifts, evolving consumer demand, and competition from lab-grown diamonds. This month’s data highlights both resilience and challenges across premium, mid-range, and lower-tier diamond grades.
Premium Grades
The upper-tier diamond categories experienced mixed movements, with some clarity grades showing resilience while others faced downward pressure. D/FL clarity diamonds saw a slight increase, rising from $12,092 in March to $12,353 in April, indicating a renewed interest in flawless diamonds, possibly driven by seasonal demand or a shift in high-net-worth consumer sentiment. D/IF clarity diamonds, however, declined slightly, dropping from $13,770 in March to $12,472 in April, signaling a softening in demand for internally flawless stones. This could reflect cautious spending among affluent buyers or competition from alternative investment options. E/FL clarity diamonds also experienced growth, increasing from $10,439 in March to $10,674 in April, suggesting sustained interest in high-quality diamonds within this color grade. These trends highlight a polarization in premium categories, with selective grades benefiting from targeted consumer demand while others face headwinds.
Mid-Range Grades
The mid-range clarity and color categories, often popular among PriceScope’s audience, demonstrated varying dynamics. F/VVS1 clarity diamonds remained stable, with prices moving slightly from $8,507 in March to $8,326 in April, reflecting consistent demand in this segment. G/VVS2 clarity diamonds, which saw a significant increase in March, faced a slight decline in April, dropping from $6,187 to $6,191. This marginal change suggests a plateau in demand following March’s surge. H/VS1 clarity diamonds showed a modest decline, falling from $4,735 in March to $4,509 in April, indicating potential inventory adjustments or a shift in consumer preferences toward other clarity grades. The mid-range segment continues to reflect strategic buying patterns, with consumers prioritizing value-focused options while remaining selective about specific clarity and color combinations.Â
Lower Grades
The lower-tier clarity and color categories remained under pressure in April, with a few exceptions. J/SI1 diamonds, which experienced a slight recovery in March, saw further stabilization, moving from $2,281 to $2,233. This suggests a continued, albeit modest, improvement in demand for budget-conscious stones. K/SI2 diamonds, however, declined further, dropping from $1,890 in March to $1,888 in April, underscoring the ongoing challenges in the lower end of the market. This decline is likely exacerbated by the growing appeal of lab-grown diamonds, which offer competitive pricing and perceived ethical advantages. The lower-tier segment remains the most vulnerable to competitive pressures from lab-grown alternatives and shifts in consumer priorities, particularly among cost-conscious buyers.
Market Implications
The April 2025 natural diamond market trends reveal a complex and evolving landscape. Premium categories, while stable, show signs of softening in certain high-clarity grades, suggesting a cautious approach among high-end buyers. Retailers should focus on targeted marketing to sustain interest in premium options. The mid-range segment continues to exhibit relative stability, with selective price fluctuations highlighting strategic consumer behavior. This segment remains a key area of opportunity for retailers seeking to capture value through competitive pricing and inventory optimization. Lower-grade diamonds face persistent challenges, driven by lab-grown competition and shifting consumer preferences. Retailers should monitor these trends closely and consider diversifying their offerings to include lab-grown options or value-focused natural diamonds.
Popular Diamond Shapes
In our latest analysis of the Top 5 Popular Natural Diamond Shapes from March to April 2025, the natural diamond market revealed significant shifts in shape preferences, reflecting evolving consumer behavior.
In April 2025, Round diamonds maintained their position as the most popular shape, though their market share declined slightly from 65.40% in March to 64.90% (-0.50%). This suggests that while the Round brilliant cut, with its optimal light performance and timeless symmetry, remains highly desirable, buyers are increasingly considering alternative designs. Oval diamonds, characterized by their elongated silhouette and high brilliance, saw a marginal decrease from 9.94% to 9.50% (-0.44%), yet continue to appeal to those seeking a contemporary yet elegant aesthetic. Pear-shaped diamonds, known for their distinctive teardrop form and versatility in various settings, dropped from 6.92% to 6.55% (-0.37%), indicating a potential shift in consumer preferences. Meanwhile, Emerald cuts, prized for their step-cut faceting and understated sophistication, experienced notable growth, rising from 5.52% to 6.30% (+0.78%), reflecting a resurgence in demand for clean, architectural designs. Cushion cuts, recognized for their soft, rounded corners and vintage appeal, continued to decline, moving from 4.63% to 4.31% (-0.32%), as buyers increasingly favor more structured and elongated shapes.
