A clear, brilliant blue or somewhat bluish-green turquoise is highly advised astrologically. When selecting a Feroza or Turquoise stone for astrological use, one should always search for a stone with few, if any, noticeable defects and good clarity. Most Persian stones are well-colored, with few if any noticeable veins or blemishes. As a result, it may be the best option for those looking for a natural Feroza stone to achieve the greatest level of success in life.
