Hey Product Hunt 👋
We built The Diamond Price Index because diamond pricing is surprisingly difficult to understand.
Most buyers can find thousands of individual listings, but it’s much harder to answer a simpler question: are comparable diamond prices actually rising or falling?
The index tracks natural and lab-grown diamonds separately, using a fixed quality benchmark and daily median asking prices. You can explore:
💎 Natural and lab-grown price movements
📈 Changes over one, three, and six months
🔷 Trends for round, oval, princess, and pear shapes
🔍 Weekly sample sizes and a published methodology
🖼️ A live index image that can be embedded in articles and websites
One result that stood out to us: lab-grown prices have fallen much faster than natural diamond prices.
The index is free, and we’ve tried to be unusually direct about its methodology, limitations, and missing data. If a series doesn’t meet our reliability checks, we don’t publish it.
I’d especially value your feedback on two things:
1. What additional comparisons would make the index more useful?
2. Would you use an API, downloadable history, or embeddable charts?
Thanks for taking a look—and I’m happy to answer any questions about the data or methodology.
