💎 June Diamond Price Trends: What’s Falling, What’s Rising, A guide for Jewelers

image

The diamond market is a dynamic ecosystem where micro-trends reveal macro-opportunities. June 2025 proved this yet again, delivering a nuanced narrative of decline, resilience, and strategic openings. While headlines scream about falling prices, intelligent investors and buyers know the devil is in the details. Let’s dissect the data, explore the "why," and arm you with actionable insights.

The June Market at a Glance: Selective Pressure, Strategic Gains

June’s diamond landscape was a tale of two markets:

Downward Momentum: Overall index down 1.2% MoM (source: IDEX Online), driven by cooling demand for smaller/mid-tier stones.

Bright Spots: Large (4+ ct), high-color/clarity diamonds defied gravity, with select categories rising up to 4.5%.

Why the split? Post-pandemic, the market recalibrates. Lab-grown saturation pressures commercial goods (under 2 ct), while natural scarcity props up elite stones. As the Gemological Institute of America (GIA) notes, "Rarity economics increasingly bifurcates the diamond hierarchy."

Round Diamonds:

Rounds (~75% of the market) faced headwinds but not uniformly.

📉 Falling Segments

1.00–1.49 ct (G+/VS2+): Down 2-3% Cause: Overproduction + fading engagement ring demand in key Asian markets (JCK Market Report).

1.50–2.99 ct (J/SI1+): Down 3-5% Cause: Inventory glut from lab-grown alternatives squeezing mid-tier naturals.

📈 Rising Segments

4.00–4.99 ct (D-G/IF-SI1): Up 0.5-4% Cause: Ultra-wealthy "asset flight" amid volatile equities. Check CaratX’s investment-grade diamonds for vetted options.

5.00–5.99 ct: Steady 1-2% gains Cause: Museums/collectors targeting "exhibition-grade" stones.

Pro Insight: The 1.25–1.49 ct H-color/VVS2-VS2 range rose 1.5-3% – proof that "nearly flawless" mid-sizers offer value arbitrage.

Fancy Shapes:

Fancies danced to their own rhythm, with cuts like ovals and cushions outperforming.

🔺 Winners

1.00–1.24 ct (D/IF-VVS1): Up 2.5-4.5% Cause: Designers pivoting to "statement solitaires" for bespoke pieces.

1.25–1.49 ct (E-G/IF-VVS2): Up 1.5-4.5% Cause: Millennial love for elongated shapes (pears, marquises) in halo settings.

🔻 Losers

5.00–5.99 ct (G-N/IF-VVS1): Down 0.5-4% Cause: "Off-color" large fancies struggle vs. D-F benchmarks.

0.70–0.89 ct: Down 1-2% Cause: Lab-grown dominance in accent stones.

Balance Point: Fancies thrive in 1–2 ct "designer sweet spot" explore CaratX’s fancy shape inventory for curated picks.

Macro Drivers:

Small-Diamond Downturn: Accelerated by India’s lab-grown export surge (GJEPC Data).

Mid-Market Squeeze: 1–2 ct rounds face "death by discounting" as retailers dump stock.

Large-Stone Immunity: Supply constraints (Argyle closure, Canada mine pauses) shield +4 ct goods. The University of Arizona Gem Lab confirms "geological scarcity is permanent."
