Most of you will know that back in 2008 I was lucky enough to find a 13th century Gold Stirrup ring


It's taken a while, and a bit of pestering through emails, but I finally have the Gold content of the ring, and analysis of the blue stone. From the British Museum.....
Non-destructive X-ray flouresence analysis of the surface of a Gold finger ring found in Durham, indicated a Gold content of 70-74%, Silver content of 14-16%, the remainder being copper. The blue stone was identified by Raman spectroscopy as corundom. Corundom with a blue coluration is known as Sapphire.
Now it's just the wait for the valuation commitee to sit in Febuary



PS...the pictures are from the BM, not mine
