Gold Sheen Sapphire Price Update 2nd Half 2017

This is the price update for Gold Sheen Sapphire for the 2nd half of 2017. It covers the reported sale prices from the September Hong Kong and Bangkok Gem and Jewelry Trade Fairs.

I have made the following changes to the chart layout:

  • Removed ‘Sell’ and ‘Buy’ prices 
  • ‘Street’ is now ‘Trade Price’
  • Reporting periods are now half yearly, not quarterly. 
  • Added ‘5 Point Moving Average’ price

Since price data comes principally from major trade fairs, ‘Trade Price’ of pieces sold is a more reliable indicator of current price. There are enough data points now to give a meaningful moving average, this should provide a good trend indicator for the future price.
