Sure, but there are limitations. I cannot infringe on any copyright or registered trademark, or replicate someone elses' work.
Well, since I have many allergies, I try to keep my space as clean as possible. My Apartment is smoke free, and I keep my workspace free of common food allergens. I do have a cat, and he does not climb on my work area or come in direct contact with my materials and supplies, but occasionally sleeps on the floor next to my supply bin when I'm working. :)
Nickel allergies are the very common allergy causing material, and I cannot guarantee your piece is free of this material, unless I specifically note that it is on the item's page.
The Federal Trade Commission, with the cooperation of the Jewelers Vigilance Commission , American Gem Trade Association, as well as several other organizations requires sellers of gemstones to declare a) if the gemstone is natural, and/or b) what enhancements have been applied to gemstones. These measures are in place to prevent unfair or deceptive trade practices. Here are the common ones I will be using: (N) Meaning it's a natural gemstone with no enhancements. (D) Dyeing: The introduction of coloring matter into a gemstone to give it color, intensify present color or improve color uniformity. (H) Heating: The use of heat to effect desired alteration of color, clarity and/or phenomena. You can find more information on gemstones and their enhancements at AGTA.com: http://agta.org/gemstones/agta-gim.pdf and http://www.firemountaingems.com/resources/encyclobeadia/charts/c76f
No, sorry. I have had too many packages to international destinations disappear in transit.
