A recent study revealed that approximately 90 percent of the turquoise gemstones available in the market are actually dyed Howlite. The physical appearances of both are exactly similar, which means that customers who are in the market to buy turquoise diamond rings may find it difficult to ensure they are getting a real turquoise ring with diamonds. This is why diamond cutters advise customers to thoroughly check the diamond certification documents of their preferred ring before making a purchase.
Turquoise gemstones were originally discovered approximately 3,000 years ago. Ancient Egyptians and Persians who were very fond of turquoise gemstones used to believe that the distinct blue color of the stone represented the heavens. Turquoise gemstones are still embedded into the entrance of several places of worship in Iran even today. The native American Indians also loved turquoise gemstones and they even believed that throwing the stone into a river will make it rain.
The Persian turquoise with a robin egg blue color is considered the finest variety of turquoise due to its unique and captivating color. Due to this, the Persian turquoise was sought after by Emperors, Kings, and Queens. This, in turn, made Persian turquoise very expensive.
