My Title - B.Tech Research Report

I have had a little trouble deciding what title to settle on for my B.Tech Research Report. "Sustainable Jewellery",  "Environmentally conscious Jewellery" or  just "Eco Jewellery", or "Green Jewellery"? Although they all seem pretty much to say the same thing. Which one best describes what it is I am trying to achieve? I thought a little reading would help so I Googled and wikipedia-ed all related words and got blasted with an overload of info. In a nut shell, i have summarized and added my own understanding of what came up.

Environmental conservation influences the protection of natural resources and ecosystems to insure their sustainable management - through changes in public policy or individual practice.
This world wide drive towards environmental sustainability has become known as 'The Green Movement'. And has brought about commonly used contemporary words/or catch phases such as environmentally friendly, Eco friendly, nature friendly and green.  As nature is largely associated with the colour green, the word has been taken on to symbolize all things environmentally conscious.

The appropriate title is definitely- "Green Jewellery".
