Terms of Use

Last updated 2026-08-26. By using Gem Index you agree to these terms.

Informational use only

Gem Index provides indicative, informational estimates of coloured-gemstone trade value. It is not a formal appraisal, a laboratory certificate, financial advice, or an offer to buy or sell. Do not rely on it as the sole basis for any purchase, sale, insurance, tax or estate decision.

No warranty

The site and its estimates are provided "as is" and "as available", without warranties of any kind, express or implied, including accuracy, completeness, merchantability or fitness for a particular purpose. Gemstone markets move and every stone is unique; actual transaction prices will differ from any estimate.

Limitation of liability

To the maximum extent permitted by law, Gem Index and its maker are not liable for any loss or damage arising from use of, or reliance on, the site or its estimates.

Acceptable use

• Do not scrape, bulk-download, resell or reverse-engineer the pricing engine or attempt to disrupt the service.
• Do not present Gem Index estimates as a certified appraisal or as endorsed by any laboratory or authority.

Intellectual property

The Gem Index name, content, design and pricing model are the property of their maker. You may reference and link to the site; you may not copy the pricing model or substantial content without permission.

Advertising

The site carries third-party advertising. We are not responsible for the content of ads or of external sites they link to.

Changes

We may revise these terms; continued use after changes constitutes acceptance. Questions: hello@gemindex.world.
