After looking at authentic dzi there's no way i can afford the price.

1) but what about synthetic dzi that arent found in grasslands by people in agricultural professions? is there any function or are they just a stone?

2) dzi are energy absorbers, correct? so they establish an equilibrium with the wearer. when ratio of bad to good energy is low, it absorbs the wearer bad energy. when the ratio of good to bad energy is high, it transfers good energy to the wearer?

3) is there any other way to cleanse dzi of previous wearer's energy than asking a high level monk?
