''Product Details
A 100% pure Baltic Amber Teething necklace made from different shaped pieces of amber in a choice of colours, every necklace is handmade so no two are identical. As with all our necklaces each piece of amber is double knotted to ensure a strong, safe necklace.
Babies do NOT chew on the amber - it works by warming against the skin and releasing minute amounts of soothing oils which is absorbed into the bloodstream.
Available in an impressive range of colours including the best seller, cognac as well as dark cognac, honey, honey light, milky and multi coloured amber.
The amber weighs between 5.5 and 6 grams, so lightweight to ensure a comfortable fit for your baby. The length is approximately 32cm so suitable from 4 months 5 years.
Amber is a natural analgesic and when worn on the skin, it releases natural healing oils that calms babies and young children to make them more relaxed whilst teething.''
