I have been tracking the price of Gold Sheen Sapphire since I first started to buy it in 2014. Recently the street price has seen a dramatic increase, certainly due to its increasing popularity with designers and investors.
From the very start Tanzim Khan (the discoverer of Gold Sheen Sapphire) has been maintaining an impressive effort to provide information and education about this new variety of corundum. I have made a fact sheet available on my website and I am working on a grading system that I am developing in conjunction with Tanzim and Gemological Labs interested in participating.
This is the two year price history of Gold Sheen Sapphire:
Some explanation about the chart.
Currently we have 3 grades for GSS:
Grade 1 – No surface defects, no structural defects, or ‘very rare’
Grade 2 – Eye clean surface, no structural defects, or ‘rare’
Grade 3 – Minor surface defects, minor structural defects. or ‘common’
Anything less than Grade 3 is not available for sale and either discarded or re-cut.
“Buy” is the wholesale price for Grade 3 stones in large quantities over 10,000 carats
“Sell” is the price offered for sale from retail or trade fare for single stones or small sales.
“Street” is the negotiated price for small quantities of stones of various grades.
Gold Sheen Sapphire can also be ‘unique’, which are typically collectors pieces over 50 carats in size. The price for these can vary from $100 per carat to simply ‘no price’ since it only depends on what the seller and buyer are willing to negotiate. Some examples of wholesale stones in calibrated sizes are on my website.
The good news is that for jewelry designers and retailers, the wholesale price of Gold Sheen Sapphire has not caught up to the street price yet.
