Perettiite – A New Mineral Discovery From Burma & 20 Years of GRS Gemresearch Swisslab AG in Switzerland

GRS announces the discovery of a new mineral; Perettiite-(Y) found in Burma (Myanmar) by Dr. Adolf Peretti which has also been named for him. Dr. Adolf Peretti mineral’s discoverer is head gemologist and director of GRS Gemresearch Swisslab AG (Adligenswil, Switzerland).

“Perettiite” was identified after months of intense lab sessions with the support of a highly accomplished team of gemologists at his GRS Gemresearch Swiss Lab AG in Adligenswil, Lucerne, which celebrates its 20th anniversary this year; one of the finest examples of collaborative endeavor between the world’s most renowned gemologists and scientists.

Perettiite-(Y) with its chemical formula Perettiite-(Y), Y3+2Mn2+4Fe2+[Si2B8O24] is a new mineral containing some of the rarest elements in the universe, such as Yttrium, Samarium, Gadolinium, Terbium, Dysprosium, Holmium, Erbium, Thulium, Ytterbium and Lutetium – the rare earth elements (REE) which were created eons ago by the unimaginable force of multiple supernovae and red giant star explosions. When our planet earth was formed, those elements ended up in nature’s laboratory more than 10 kilometers below the earth’s surface where the Indian and Asian subcontinent collide; it was there that Perettiite was formed as fine needle inclusions in gemstones.

“Realizing that Perettiite is actually like a fingerprint containing elements like an echo from billions of years of history of the universe, made me unbelievably humble”, Dr. Peretti says.

Locating and retrieving samples of Perettiite was yet another of the many expeditions Dr. Peretti has taken upon himself during his thirty years of scientific discoveries. It lead him close to Momeik, an area about 30 kilometers north of Mogok in Burma, during an ongoing war between the Kashin state and the Burmese government. It is an area where, according to him, “the geology goes crazy and still a lot of research is needed to bring all the puzzles together.” It’s in this “Terra Incognita” in Burma that Perettiite was found, which very much reflects his lifestyle – always pushing the edge of science forward. With the help of a local geologist, Dr. Peretti was able to acquire sample materials from behind the front-lines and forward to his team at the GRS Gemresearch Swisslab AG in Lucerne (Switzerland).

Dr. Peretti commissioned the renowned French television TF1 film-maker Vincent Reynaud to shoot his new movie “From Rock to Treasure – A Lifetime Experience”. The documentary follows the journey of a ruby from its discovery in the mines of Burma along through the cutting process of a high value ruby rough.

A celebration of Dr. Peretti’s lifetime of scientific discoveries, the premiere of his new movie and the baptizing of an actual “Perettiite” crystal, together with a “Thank You & 20th Anniversary Party” for all supporters and scientists who helped GRS Gemresearch Swisslab AG to become the vibrant and well-equipped state-of-the-art Swiss laboratory which it is today, was held on 29th August 2015 at the Park Hotel Vitznau in Switzerland.


Dr. Peretti Discusses Perettiite

“This is a fantastically beautiful needle-like orange mineral with a new crystal structure that I discovered in the Mogok market. It actually originates from Momeik, however, I had never seen anything like this so I sent it to our scientists’ network in Switzerland,” explains Dr. Peretti. “Notice the phenakite inclusions in this image of Perettiite. It is a miracle of nature and certainly a pinnacle in my career for which I could never have imagined! Thanks to the scientists whose efforts rescued and decoded this unique natural creation. It would have been lost forever had we not had such brilliant scientists and the elite technology available to us.

Further crystallographic details for leading insider crystallographers on the new mineral Perettiite-(Y) will be included in the next edition of European Journal of Mineralogy at press now and will be released in time for the celebration.

“This is one of the finest examples of collaborative endeavor between gemologists and scientists in the world of mineralogical discoveries. No wonder no one had identified it yet.” Dr. Peretti said. “It needed the utmost effort from the world’s most renowned mineralogists.”
