Converting a tumbled stone into jewelry?
Gemrock Perus high quality polished tumbled stones allow for creating stylish jewelry for a demanding customer.
You can buy our tumbled stones to make your own jewelry or buy finished jewelry from us.
A word about silver:
Studies in Europe and the United States have shown that so called sterling silver manufactured in China and India (and probably elsewhere) in most cases contains toxic metals like cadmium, lead and niquel, that have been mixed into the silver in order to save money. In some cases investigators have found up to 44% of cadmium content in silver jewelry from India.
This silver from India and China may be cheap, but it puts the health of your customers at risk.
Also: The famous 925 stamp on the sterling silver jewelry is of no use at all. These stamps are put on the jewelry by the producer itself. There are no governmental or independent entities supervising or controling the use of this stamp. In most countries there are not even regulations concerning the contents of toxic metals in jewelry.
We at Gemrock Peru have joined ranks with a new jewelry company and do produce our own sterling silver from pure silver. Our sterling silver is real sterling silver (92.5 % silver and 7.5% copper), no matter if stamped or not. Our sterling silver is free of any tocix metals.
How can you be sure?
We can teach you how to perform an acid test on our batches that will not damage the jewelry but proof that our silver is real and good.
Improved shine and anti-tarnish:
Whenever the jewel design allows for it, our sterling silver gets an electrolytic bath in fine silver (99.99 % pure silver) and in anti-tarnish. This way we can give you a 9 months guarantee that our silver will not tarnish. If you store and treat our silver jewelry the way we will recommend in the care instructions that come with your order, you can massively prolong the time of our anti-tarnishing guarantee.
