Our jewelry is handcrafted by Lithuanian artisans, known locally as Masters, who carefully polish and round the shape of each Baltic amber bead so it rests gently against the skin. The string in each of our amber necklaces and bracelets is knotted by hand in between each and every bead, so should the necklace break, the rest of the beads will not scatter. In the unlikely event that a bead should be ingested, amber is a non-toxic substance and is not harmful. The necklace fastens with a plastic amber-colored clasp that opens and closes easily. All amber is fossilized tree resin, however only amber mined from near the Baltic Sea, known as Baltic amber, contains concentrations of succinic acid, a naturally occurring substance already produced by the body and in many other plants and animals. When worn on the skin, Baltic amber releases an oil containing succinic acid which is absorbed in small amounts. Our customers have reported the succinic acid to work like a natural Ibuprofen, safely dulling pain and reducing inflammation, and reducing dependancy on traditional painkillers. To function well, the amber jewelry must be worn close to the source of pain. Note that its an alkalinizing acid (like lemon juice) so it wont add to your bodys acidity, and may actually slightly lower it. Baltic Amber has some of the highest concentrations of succinic acid found in nature. The salt of succinic acid (succinate) is one of the most active substances in the processes of cellular respiration and intercellular energy creation. Baltic amber has been safely used in Europe for hundreds of years, there are no known unwanted side effects. Much more information about baltic amber is available at Hazelaid.
