("Shefa Gems" or the "Company")


Carmeltazite was chosen to be Mineral of the Year 2018

by the International Mineralogical Association (IMA)

Shefa Gems (LSE: SEFA), a company focused on advanced exploration and development of multi-gemstone projects in Northern Israel, is delighted to announce that the International Mineralogical Association ("IMA") Commission on New Minerals, Nomenclature and Classification has chosen Shefa Gems' Carmeltazite as its Mineral of the Year for 2018 (

Carmeltazite is a complex oxide (ZrAl2Ti4O11) which forms black inclusions in blue corundum crystals from Cretaceous pyroclastic rocks and associated alluvial deposits at Kishon Mid-Reach in northern Israel. Its name alludes to its discovery at Mt. Carmel and the three principal metals in its formula (Titanium, Aluminium and Zirconium). Carmeltazite was discovered as part of an academic collaboration involving distinguished geologists from Macquarie University, the University of Western Australia, the Università degli Studi in Italy and Shefa Gems.

Since the Carmeltazite description was published in Minerals (Griffin et al., 2018), Carmeltazite has gained significant publicity online as "the world's newest gemstone" (EraGem, 2019), and even as an "extraterrestrial mineral harder than diamonds" (Flatley, 2019). Although in fact it is perfectly terrestrial in origin, Carmeltazite contains Ti3+, which is rare in the geological environment, and has a peculiar crystal structure, which is reminiscent of the close-packed arrangement of spinel.

Vered Toledo, CEO of Shefa Gems, said: "I am excited, happy and thankful for the great honour we have received from the IMA and the recognition of our unique Carmeltazite. The association of Carmeltazite with other Ti3+ and carbide minerals, indicates very unusual geological conditions in our volcanic source rocks which presages new and exciting discoveries in the future. Carmeltazite is an integral part of our unique and rare gemstone Carmel SapphireTM."
