Key Development:

United States: Recent Lab‐Grown Diamond Developments

✅ In October 2025, the Gemological Institute of America (GIA) launched a new quality‐assessment service for D‐to‐Z lab‐grown diamonds, replacing the detailed 4Cs grading with simpler categories: "Premium" or "Standard."

✅ In October 2025, GIA clarified that stones failing to meet the minimum criteria under the new LGD quality‐assessment system will not receive a full report, but still be evaluated (at a lower fee), and will be laser-inscribed "laboratory-grown" with a GIA assessment number.

✅ In October 2025, the CVD lab‐grown diamonds segment was reported to grow from US$ 12.75 billion in 2024 to US$ 13.81 billion, underlining continued strength in synthetic diamond manufacturing globally.

✅ In October 2025, industry analysts alerted that prices of 1-2 carat lab-grown diamonds have plummeted, hurting consumer confidence and signaling oversupply issues.

Japan: Recent Lab‐Grown Diamond Developments

✅ In October 2025, research commentary highlighted that lab-grown diamonds in Japan are attracting more designer and colored stone collections, driven by broader product variety and shifting consumer tastes.

✅ In October 2025, reports noted that synthetic diamond production in Japan is being eyed for higher technological use (not just jewelry), helping expand demand beyond traditional markets.

✅ In October 2025, the global pricing collapse in lab-grown diamonds (especially in China and India) was called out as a risk also for Japanese producers competing in export markets.

✅ In September 2025, the World Diamond Council head publicly warned that lab-grown gems are "losing their sparkle" because of oversupply and declining prices-comments that could influence regulatory and trade sentiment in Japan's diamond trade.
