Natural Diamond Prices in 2026
Natural diamonds continue to dominate the high-end jewellery market, but prices have experienced notable fluctuations. Retail prices for smaller and lower-grade diamonds have generally declined, with some reports suggesting up to a 40% decrease from 2021 peaks, largely due to competition from lab-grown stones.
However, high-quality, ethically sourced, or large-carat diamonds have experienced modest price growth of around 15%, reflecting their rarity and ongoing demand.

Value Retention: Moissanite vs Diamond
While price is important, value retention is a key factor for many buyers. Diamonds, especially natural stones, outperform moissanite in this area due to rarity and established market demand.

Moissanite is designed for affordability and visual appeal, rather than resale value. Natural diamonds continue to hold their market value better due to scarcity, certification, and traditional desirability, while lab-grown diamonds sit in the middle.
Why Moissanite Is a Budget-Friendly Alternative
Moissanite’s cost-effectiveness stems from lab production, which eliminates mining costs and allows for precise control over size, clarity, and color. A 1-carat moissanite can cost up to 90% less than a similar natural diamond, while still offering exceptional durability and brilliance.
