Gents,

I was asked to translate short Polish text into English. My friend wants to put it into elegant card attached to jewelry she makes.
May I ask you gentelmen to read my poor translation below and make all the corrections to make it like written by British/American native from jewelery business? To become correct, distinguished and royal English as possible Smile
Thank you in advance.

Here is the text:

"Dear Cusomers,

Congratulations on purchasing this unique jewelry handmade in traditional methods by Polish goldsmith manufacture.
All the models from our collection are based on historical patterns.
The jewelry has been made from silver of 925 hallmark electrically covered with a 3 microns layer of red gold, which ensures exceptional durability and long use without the risk of jewel’s colour changing.
There have been used stones and crystals of first quality only in whole collection.
We recommend to avoid direct contact of jewelry with perfumes, cosmetics and salt water"
