In my healing practice, I use Golden Topaz as a "re-charger" in any situation that needs a boost either physically or spiritually. In Feng Shui it can be placed in the Helpful People bagua as an attractant or in the Career/Fame bagua to help you understand and promote your own abilities with charisma, charm, and confidence. It is one of the premier stones when one must energize, heal, cleanse, amplify and recharge on any level. Emotionally and physically it has an immediate and powerful effect to uplift and bring light into the aura. I recommend it as a basic staple in any medicine bag.
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.
