An expert gemmologist, Dr Gavrielov Gila, has valued cut and polished blue sapphire from the Kishon Mid Reach deposit owned by Shefa Yamim (ATM) LTD (LON:SEFA) at US$7,000 per carat.
Natural moissanite from the same project was valued at US$10,000 per carat.
Dr Gavrielov has over 40 years of expertise and experience in the appraisal and purchase of precious stones for use in jewellery.
Highlights of her career include joint ventures with Rapaport and the British Gemmological Institute evaluating gemstones, diamonds and jewellery. She has also established a jewellery design business.
The Natural moissanite found at Kishon Mid Reach is the largest in both volume and size ever found globally, with single crystals running at greater than four millimetres.
The Carmel sapphire is not found anywhere else in the world and is formed of the rare mineral carmeltazite, a newly discovered mineral internationally recognised by the International Mineralogical Association Commission on New Minerals, Nomenclature, and Classification.
Additionally, black Carmel sapphire was valued at US$5,000 per carat cut and polished, and valuations were also given for a suite of other gemstones and mineral sands.
“This is the first time ever that a large variety of precious and rare gemstones has been found in one deposit,” wrote Dr Gavrielov in her report.
“This is the reason why Shefa Yamim has called itself a "multi-commodity" exploration company. In my opinion, not only are the gems singular in their rarity and origins in the Holy Land, but the mine life is limited to an approximated 15 years maximum. This limited availability adds to the value of the gemstones."
