Natural diamonds (natural and enhanced – see below) should be listed in the Fine Jewelry category.
A diamond is a mineral consisting essentially of pure carbon, crystallized in the isometric system with a:
Hardness of 10
Specific gravity of approximately 3.52
Refractive index of 2.42
Diamond creation and enhancement:
When listing a diamond, you must include information about what type of diamond you are listing, as well as the gemstone creation method of the diamond, in the title, item specifics and description.
Natural, Not Enhanced: Choose this option only if you have an unenhanced, natural diamond.
Enhanced: If you are listing a natural diamond that has been enhanced (for example, “clarity-enhanced” to reduce flaws, dyed, etc.), you are required to include “enhanced” in the title and to specify the enhancement in the item specifics and description.
Lab-created: Select this option only if you are listing a lab-created diamond that has the same mineral composition as a natural diamond. Do not list a lab-created diamond in the Fine Jewelry category unless it is accompanied by a fine metal setting or other fine gemstone. You are required to identify the diamond as “lab-created” in the title, item specifics and description immediately preceding the name of the lab-created diamond. All lab-created diamonds not mounted on a fine metal setting or accompanied by a fine gemstone should be listed in the Fashion Jewelry category.
Simulated: Select this option if you are listing a simulated diamond that has the same appearance but not the same mineral composition as a natural diamond. A simulated diamond should only be listed in the fashion jewelry category unless it is mounted on a fine metal setting or accompanied by a fine gemstone, in which case it should be listed in the Other or Simulated categories. If the mineral composition of the diamond is different from the natural diamond, you are required to identify the diamond as “simulated” in the title, items specifics and description immediately preceding the name of the simulated diamond. All simulated diamonds not mounted on a fine metal setting or accompanied by a Fine Gemstone should be listed in the Fashion Jewelry category.
Unknown: If you do not know if the diamond has been enhanced, or if it is lab-created or simulated, you should consider having the diamond certified. All unknown diamonds should be listed in the fashion jewelry category unless mounted on a fine metal setting or accompanied by a fine gemstone.
Gemstones not meeting the definition of a diamond:
If the gemstone does not meet the above definition for a diamond, you cannot list your item in the Diamond or Fine Jewelry category. If the mineral composition of the gemstone is different from the natural gemstone, you must clearly identify the item as such in all areas of your listing. For example, use words like “simulated” immediately preceding the use of diamond. You must also clearly describe the actual material the gemstone is made of in the item specifics and description, such as:
