Nickel White Gold Protection

This is a post I wrote a few weeks ago. I never put it up as we decided to completely remake the ring in a non toxic gold alloy so she wouldn't have any possible nickel or toxin exposure, but there is some good possibility along the vein we explored here for people who do not or cannot remake their jewelry:

Today I am working on a ring of someone special to me, and once again I am forced to overcome the shortsightedness and lack of consideration by this jewelry industry. Her fiance got her the ring because it was simple, which is what she wanted, white gold as it is precious and had a Canadian diamond for a touch of tradition (which was nice for them too as they're Canadian). However, at no time when he was purchasing the ring was he told what the white gold in the ring was alloyed with. Almost no one does, as it is not brought up during sales presentations and there aren't any pretty and lacy full page ads in bridal magazines talking about the perfect alloy to go with a sparkly new diamond. He proposed to her and she wore it every day as most newly engaged do. As time went on, she started to develop an itchy finger, which soon turned into a full blown rash. She was perplexed, and had no idea her body was trying to fight off and reject the ring. They had no idea the ring was alloyed with Nickel, a heavy metal that causes cancer with prolonged exposure, then shuts down the immune system so our bodies can't fight it. As well, once in the body, it is very difficult to get rid of. The ring is special because he gave it to her, and yet she can't wear it because she breaks out as soon as she puts it on.
After lots of brain storming and feeling my way around how to help her (you may have noticed a previous post says we weren't taking in any nickel white gold jewelry because it is unsafe to work with) I believe there is a way to help. The main problem is the contact with the skin, as it is absorbing the nickel which breaks down and leaches out of the ring from her sweat and chlorinates (pools, cleaning products, shampoo, tap water etc). The idea is, create a non-toxic and allergy free barrier (her body has already grown more sensitive to metals from her ordeal). A problem is, to put a liner inside we will have to make the ring larger as the liner will make the inside of the ring smaller. We can't size her ring by cutting or grinding as it will expose the jewelers themselves to the nickel in a much worse form, dust. Instead, we will be stretching the ring larger by cold forging. Very different from hot forging, which heats up the metal to the point it begins to de-gas which would release the nickel into the air as a vapor, worse than dust. We will cold forge by simply hammering the ring larger, preventing any release of nickel via dust or vapor into the air we breathe!
The liner itself will be made of platinum iridium, a non toxic and hypoallergenic alloy. We will make a tube, put it through the inside of the ring and fold it around the edge of the ring, then laser weld the liner to the ring to create a sealed and seamless barrier. No soldering, as that would result in the metal heating and degassing the nickel.
I am very excited about this, as it is a potential to help people who love their rings and either can't or don't want to remake them enjoy their jewelry without absorbing all the toxins contained within!

With Everything,
