Why consider such metals for jewelry purchase?
First, these metals are plentiful in the environment, you do not have to be concerned with the excess amount of mining and processing that takes place with precious metals (better for the environment). Second, due to the high supply in the market compared to precious metals, their costs are reasonable. Finally, the jewelry designs and styles are impeccable and rival those of precious metal jewelry.
When purchasing jewelry consider the following eco-friendly tips:
1) Consider purchasing vintage jewelry (it's a form of recycling).
2) Consider purchasing recycled jewelry (avoids excess mining for precious metals).
3) Consider alternative metal sources such as the example from www.titaniumkay.com.
4) Consider purchasing handmade jewelry source from fair trade practices. In addition to helping those in need, it makes a great statement piece.
Finally, consider whether you are actually going to wear the piece and how often. If you need a piece for a special occasion, consider borrowing the item. Celebrities always borrow high end jewelry for major occasions and really stick with 2-3 key jewelry items for daily wear so maybe they are on to something.
