Amber is a strong overall healer and cleanser. It has a warming and uplifting quality that is ideal for those who need an extra energetic but gentle "boost." I like to use it during the winter's darker months to bring a ray of sunshine to the winter "blahs" as Amber will quickly start to absorb negative energies and help build a positive, sunny mood and disposition.
A rough version of crystal is usually cut from a much larger piece of mined material that is too large or heavy to be used by a person. Rough chunks such as calcites are often acid washed to subtly smooth out rough edges that may cause cuts or injury and to prevent further flaking or breakage.
