According to “The Classic Cuisine of Soviet Georgia,” it’s dried leaves, not the seeds.The Latin name is Trigonella caerulea, English name sweet trefoil. In Switzerland they call it Schabzigerklee and use it to flavor Schabziger cheese (Sap Sago).
Not sure this will help but a dear Russian friend brought me a number of Georgian spices from this company, https://kitchenceremony.com/. Their webpage is written in Cyrillic, and I think it is in Russian, not Georgian. It is giving Google Translate a headache. If you have any Russian speaking friends to translate I am sure they carry it. My friend gave me a number of Georgian spices I was able to identify thanks to this website, https://georgianrecipes.net/.
