Start with a verbal color check
We’ll contact you with the result by the next business day, subject to availability.
What we can check & how it works
Ask for a Verbal Color Analysis* at submission and we’ll tell you how we would describe the color on the report. This could include what color type it would get (Pigeon’s Blood, Royal Blue, etc.) and/or what hue, tone and saturation will appear on the report.
Things we can check for
- Will the report say Pigeon’s Blood, Padparadscha, Royal Blue, etc.?
- Will my stone be considered a pink sapphire or a ruby?
- Will my stone get a vivid saturation?
- Is my stone a color change?
- Is my spinel Cobalt Blue?
- Will my stone be “purplish red” or just “red”?
- Will you mention the term “Paraíba” on my report?
*Important limitations of Verbal Color Analysis
The verbal color analysis is a strictly verbal, non-binding visual check of a stone’s color. The final color call on a report is still contingent on further gemological testing.
Loose gems or jewelry
We test both loose gems and gems mounted in jewelry. Loose gems are preferred for the most accurate examination.
For mounted gems, we examine as fully as the setting allows. If the setting limits testing, we may ask you to have the stone unmounted.
Gold, Silver & Black
Lotus cover colors reflect the testing findings.
Gold
Natural gems with no enhancement beyond cutting and polishing.
Silver
Natural gems enhanced to better display their beauty.
Black
Synthetic and/or heavily treated gems.
