Writing of 10 Jewelry articles

I need 10 articles for jewelry-related site. The articles must be original and never published before - no copy-pasting (this will be verified). After you receive payment - you tranfser all copyright rights to me. Therefore you can't give/sell this content to anyone else. The articles must be written in clean English, 400-500 words per article. No sales pitch whatsoever, no links to any sites, just plain information about jewelry, how good it looks, where it used, how to take care of it, history, etc. A list of keywords to base your articles on will be given to you if you need it. Example of previous articles will also be given. Example keywords could include "jewelry rhodium" (example article based on this keyword: "The usage of rhodium in jewelry"), "jewelry tibetan" (ex.: "What's special about Tibetan jewelry"), etc. No SEO work needed, no need for specific keyword frequency, this content is written for human readers and therefore must be at least a little valueable - meaning the user who reads must get to know something new and/or interesting from the article. The proposed method of writing is searching internet for info on subject and writing the articles in your own words basing on gathered facts. The project is for testing your skills, later I am planning for ordering much more. The payment will be made via GAF escrow account. The price is 10$ per article or less. The lesser your bid - the better. Please send 1-3 links to your previously written articles or the text of articles.
