Gemstones
Authentic gemstones
Allowed
Authentic gemstones that have been enhanced can be listed in the Fine Jewelry category as long as you select the correct Main Stone Treatment when listing the item. For treated gemstones, you also need to clearly specify in your listing if the treatment is one of the following:
· The treatment is not permanent and loses its effect over time.
· The treatment creates special care requirements for the gemstone to retain the benefits.
· The treatment has a significant effect on the gemstone's value.
Manufactured gemstones
Not Allowed
Manufactured stones can be listed only in these categories:
· Engagement & Wedding
· Fashion Jewelry
· Categories especially designated for them (for example, the Pearl, Imitation category or the Simulated Stones category)
· Other
Don't list manufactured stones in the Fine Jewelry category or in any categories intended for genuine gemstones.
If the mineral composition of the stone or gem is different from the natural mineral, you must clearly identify the item as such throughout your listing. For example, use words like "imitation pearl" or "simulated ruby" in both your listing title and your description.
Fine Jewelry
To list items in the Fine Jewelry category, both the setting and the stones (if there are any) must follow these guidelines:
Allowed
· Precious metal settings of 10 karats or higher, silver of 925 parts per 1000 pure silver or more, or platinum group metals of 850 parts per 1000 pure platinum or more
· Natural stones or stones with the optical, physical, and chemical properties of natural stones
· Pearls, naturally formed or cultured
· Diamonds, as long as they follow the guidelines below
Not Allowed
The following kinds of items should only be listed in the Fashion Jewelry category:
· Plated or filled metal
· The setting is solid precious metal, but the stones are manufactured
· The stones are natural, but the setting is plated or filled metal
· The main stone is natural, but the accent stones are manufactured
· The accent stones are natural, but the main stone is manufactured
Precious metal
A precious metal is defined as:
· Gold of 14 karats or higher
· Silver of 925 parts per 1000 pure silver or above
· Platinum group metals of 850 parts per 1000 pure platinum or above
Solid precious metals cannot be plated or filled. If your item doesn't qualify as a precious metal, be sure to follow these guidelines:
Diamonds
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
Stone Treatment:
When listing diamond jewelry, you must select the Main Stone Treatment that matches the diamond's characteristics:
· Natural, Not Enhanced: Choose this option only if you have unenhanced, natural diamonds.
· Traditional, Normal Enhancement: If you're selling natural diamonds that have been enhanced (for example, "clarity-enhanced" to reduce flaws), you should specify the enhancement by using item specifics.
· Other (Diffusion, Dyed, etc.): If the diamond is altered or enhanced but does not fall into the above category.
· Unknown: If you don't know if the diamond has been altered or enhanced.
Loose diamonds:
When listing loose diamonds, you must sell them in the category that matches the diamond's characteristics.
· Diamonds (Natural): Select this category only if you have unenhanced natural diamonds.
· Diamonds (Enhanced Natural): Select this category if you have natural diamonds that have been enhanced (clarity-enhanced to reduce flaws, for example).
· Diamond (Lab-Created): Select this category if you are selling diamonds with the same mineral composition as naturally mined diamonds but that are lab-created. While lab-created diamonds can be listed in the Diamond or Fine Jewelry category, you must list them in this category and indicate in your item description that the diamond is lab-created.
Rough Diamonds:
All rough diamonds must be listed in the Loose Diamonds & Gemstones > Diamonds (Rough Natural) category and must comply with the Kimberley Process Certification Scheme (KPCS), an international initiative to control and monitor the trade of rough diamonds. Countries participating in the KPCS, including the United States, prohibit the import or export of rough diamonds to non-participant countries. In addition, shipments of rough diamonds from or to a participant country must be controlled through the KPCS.
All listings for rough diamonds on eBay must state that the seller complies with the Kimberley Process and that the diamond is accompanied by a Kimberley Process certificate. For more information on this process, visit the US Department of State website.
Stones not meeting the definition of diamond:
If the stone doesn't meet the above definition for a diamond, you can't list your item in the Diamond or Fine Jewelry category and you can't use the word "diamond" in your listing title or description. You should describe the actual material the stone is made of, such as:
· Briolite
· Cubic Zirconium
· Diamonique
· Glass
· Moissanite
· Plastic
· Quartz
· Rhinestone
· Strontium Titanate
