Idex July 2026 Price Report

General

Pre-holiday trading showed stable to slightly higher demand in the U.S. and Europe. The Chinese market is showing initial signs of recovery, although consumer demand remains focused on non-set gold jewelry.

1/6ct and Below

The size category that experienced the sharpest decline in 2026 is finally showing signs of stabilization. Our upcoming Rough Price Review also indicates early signs of stabilization in the rough market, with modest price recovery.

Pointers (0.20ct to 0.90ct)

This size category, which weakened over the past three years, is beginning to show positive signs.

Fancy shapes recorded price increases, particularly in the 0.70 to 0.90ct category, while smaller sizes remained stable.

Round diamonds remained generally steady, with price increases in 1/5ct lower-color goods. We attribute this improvement to renewed demand for lower color categories generated by De Beers' Desert Diamonds campaign, which celebrates warm hues such as "sand" and "honey." This color segment had seen very limited demand over the past three years.

4 to 6 Grainers (1.00 ct to 1.99 ct)

Fancy shapes recorded a general increase in prices, mainly in better-quality goods.

Round diamonds were relatively stable, with price increases concentrated in the 1.50 ct category.

2ct to 4ct

Fancy shapes experienced stronger demand, with price increases mainly in VS2 and higher clarities, while SI2-SI3 goods saw some price weakness.

Round 2ct diamonds recorded price increases in better clarities across the G to L color range. The 4ct category also performed well, with price increases in D to N colors and VS1 and higher clarities.

5ct

Fancy shapes recorded stronger demand, particularly for D to I color, IF clarity goods. Demand for other qualities remained stable, while VS2 and lower clarities experienced some price declines.

Round diamonds had a somewhat weaker month, with modest downward price adjustments in most categories.
