What happened
Cormac Kinney discussed trends in the diamond market on CNBC on September 26, 2026. Kinney noted that natural diamonds have lost more than half their value over the past five years. The average price for a 1-carat stone is currently $3,898, down from an average of $8,007 in 2021. This decline is occurring amid a glut of mined stones and the rise of lab-grown diamonds.

Why it matters
The Diamond Standard Index, which tracks investment-grade diamonds, recently hit 2,490, marking its lowest level ever. Kinney attributed the market pressure to the initial excess inventory from 2023 and 2024, compounded by the availability of lab-grown alternatives.
