Frequently Asked Questions
Do I need to know gemology to use the guide?
No. The guide starts with the fundamentals and organizes entries by family and variety, with an index of common names. You can start with the gem you want to learn about and refer to the explanations as questions come up.
Can I authenticate a gemstone using an image from the guide?
No. The illustrations help you compare observable characteristics, but appearance and photographs cannot establish the identity, treatment, or provenance of an individual piece. For information about a specific piece, consider the stated details and available documentation.
Are the listed prices appraisals of specific pieces of jewelry?
No. The value references are approximate and include the unit, currency, date, condition, and source. The guide also distinguishes a value reference for a loose gemstone from the price of a finished piece of jewelry; it does not appraise individual pieces.
What's the difference between the Basic and Complete Plans?
Both plans include the complete main guide. The Complete Plan adds the three selected supplementary materials: jewelry storage panels, gemstone cut shape charts, and a timeline of gemstones in jewelry.
What is the purchase guarantee?
The stated guarantee for both plans is lifetime and unconditional, under the terms presented on this page.
