Ok so after much debate I bought this necklace. I have lots of food sensitivities as well as late stage lyme disease, have had many surgeries, and am in quite a bit of pain sometimes. I tend to be a little too acidic. So I bought this necklace.

I have worn it continually for about 2 months now, taking it off only for bathing (but I do get it wet as directed) and One christmas party. The inner wood is starting to darken, like they say it would if you are quite acidic, but in all honesty- I don't feel a whit different. And it certainly has NOT helped with acne. As it is just past christmas, and I ate some foods I shouldn't have I have a big ol' zit right above the necklace (but not caused by it).

I DO LIKE this necklace. I like that it is a smaller company. They put a lot of thought into their product. I like the natural materials, they are beautifully made. But whether it will heal all your woes?
  Also- I am allergic to most metals. Like nickle and such, I have to be very careful with belt buckles and earings, necklaces... so far the clasp has not bothered me. What ever it is made out of (aluminum?) it is exceptionally light weight. I feel like I'm going to break it, yet after playing with it for so long now, every time I bathe- I have decided it is actually quite sturdy.

I do NOT like that this is too light. The problem with that is it is constantly spinning. It weighs less than a bird its so super light. So I would suggest getting one of their necklaces with a gem stone in front to keep it more comfortable and aesthetic. My 2 year old is constantly reminding me its backwards. The light weight aluminum-ish clasp is the heaviest thing on here!
  Also it is either too long or too short for an adult woman. Every time I bend over it falls over my chin and gets caught on my mouth, and is too tight to fall back down. Seems silly, but its REALLY annoying after the fifteenth time a day, every day.
  The image is not quite right either, if I knew how I would have added a picture, but mine doesn't have a Single large amber in the front, it has 5 pieces of the same size. My 2 year old loves counting them. Ha ha ha... who would have thoght a necklace that teaches counting!

Okay so seriously- for the price of jewelry in general, these are worth buying just because they are lovely. Just don't get your hopes up, but you never know, maybe they will help. For me, diet is EVERYTHING in pain and acne management. No dairy (sad face) no gluten (hello- my background is itallian), no sugar, no grains. Lots of healthy meat, Lots of veg, and some fruit.

Best wishes to you and yours.
