Frequently asked questions
Everything you need to know before subscribing.
The 7-day free trial gives you full access to search, filter, and navigate the entire GemmoPrice database. All records and filters are active — prices are masked during the trial period. This lets you experience the full depth of the search tools and understand exactly how the platform works before committing to a subscription.
All plans — Silver, Gold, and Platinum — include identical access to the full GemmoPrice database. There are no feature tiers or data limits. Every record, every searchable field, every image, and every direct link to the original auction lot is available to all subscribers. The only difference between plans is the subscription duration.
No. GemmoPrice is a professional market intelligence tool, not a valuation service. The database provides real auction results — pre-sale estimates and hammer prices — from leading international jewellery sales. This data is intended for use by trained professionals as a reference and analytical resource. It does not constitute a formal valuation, a price guarantee, or investment advice. Gemstone prices are influenced by many factors beyond the searchable parameters, and comparable stones can achieve significantly different results at auction.
GemmoPrice currently covers specialized jewellery sales at Sotheby's, Christie's, Bonhams, Phillips, Artcurial, Heritage Auctions, Koller, and Boetto. Coverage spans from 2011 to the present and is updated with each major new sale. Note that colorless diamonds below 5 carats are excluded from the database — GemmoPrice focuses on the complex market for important colored stones, fancy color diamonds, and significant white diamonds where professional judgment and market intelligence matter most.
Subscriptions are individual and linked to a single user account. However, you can share search results, comparables, and reports with colleagues and clients directly from within the platform.
Subscriptions are fixed-term and do not auto-renew. At the end of your plan period, you will be notified and can choose to renew. For any questions about your account, contact us at info@gemmoprice.com.
