GRS laboratory reports for important gemstones signed by Dr. A. Peretti have been referenced in catalogs of internationally acclaimed auction houses all over the world, starting more than two decades ago.

Currently, he serves as the CEO and owner of GRS laboratories. In 2015, Dr. Peretti discovered the new mineral Perettiite-(Y), Y3+2Mn2+4Fe2+[Si2B8O24], in Burma (Myanmar), which was named in his honor.

In 2020 the Peretti Museum Foundation was established. The foundation's purpose is the operation of its own museum with exhibitions covering the topics of paleontology, mineralogy, and earth sciences. The extensive amber collection with inclusions of lifeforms shall be conserved for the public and science and shall be made available for researchers. The foundation aims to describe new minerals and extinct and non-extinct lifeforms in various international journals.

In November 2020, a newly discovered amphibian animal species with a ballistic tongue was named Yaksha perettii in his honor, as published in the prestigious journal Science.
