If you’ve been watching the diamond market—or browsing for an engagement ring—you may have noticed a recurring theme in late 2025: natural diamond prices are softening. Industry reports, including Rapaport market insights, show widespread price declines across several natural diamond categories.
So what’s really going on? And more importantly:
Is now a good time to buy a natural diamond in Australia?
Let’s dive into the trends you actually need to know.
Why Are Natural Diamond Prices Falling in 2025?
1. Global Demand Has Shifted
Consumer behaviour has changed. While jewellery continues to be loved, broader economic uncertainty has softened demand for mined stones—especially in the U.S., India and China. That naturally applies downward pressure on prices.
2. Lab-Grown Diamonds Are Thriving
Lab-grown stones are booming across Australia and globally. Their affordability and sustainability story have encouraged many couples to comparison-shop across both categories.

3. Oversupply in Select Carat Ranges
Wholesalers and cutters are holding excess inventory in certain shapes and sizes. When supply outweighs demand, pricing adjusts.
4. Macro & Market Forces
Geopolitical changes, polished supply bottlenecks, sanctions, and fluctuating currency markets have all contributed to unpredictable pricing behaviours through 2024–2025.
