Natural Baltic amber has the highest concentration of succinic acid. The acid is released when the raw nugget comes into contact with the skin. We can see it perfectly on non-glossy amber (it gradually covers itself with a thin glossy layer). Formed over millions of years, amber crystals have retained many of the sun's energy and healing properties.
If you are looking for jewelry that will not only look beautiful, but also provide benefits: necklaces with bark - thyroid gland activity. Bracelets with amber peel - for joints.
