Lotus Hardcover Reports: The New Standard
Lotus Hardcover reports are elegant, highly customizable 15+ page reports with full-color photographs created to celebrate the rarity and value of gemstones. These reports enhance the value of your most precious stones by reinforcing the rarity and beauty of these gifts of nature. The Gold cover is strictly reserved for gems that are completely natural, with no enhancements beyond ordinary cutting and polishing. The hardcover report includes all of the identification information in the softcover report, with the addition of more extensive information and imagery. These are customized to suit the subject of the report and can include information on:
- Connoisseur's guides. How to recognize fine ruby, sapphire, and spinel with information on color and clarity.
- Origin. Maps, photos, and further details about the stone's origin.
- Pairs and sets. We describe the rarity factor and work that can go into composing matched suites.
- Additional photos. Inclusion photos, photos of suites or jewelry sets, and other additional images available on request.
- Padparadscha. A special supplement is included for padparadscha sapphire.
- Special Report Appendices. Customized special comments on the finest stones. These comments are only issued at the discretion of Lotus gemologists, and are only available with hardcover reports.
