Under this study, an interdisciplinary classification is developed concerning the entities of the gemological law. The classification is grounded in a symbiosis of criteria that define the content and scope of responsibilities, type of gemological activity undertaken, and the condition and appearance of a gemological object. The classification holds practical applications in mining, jewelry, business and management. Additionally, it can be employed in academic studies focusing on theoretic advancements in gemology, mineralogy, geology and jurisprudence. Introduction of this classification into the current legislation would enable both the entities of gemological law and law enforcement to integrally understand the spectrum, possibilities, forms and means of fulfilling their interests, along with their interrelations with other stakeholders. This research underscores that the primary criterion for developing an interdisciplinary classification of gemological law subjects is the type of gemological activity. Its symbiosis with other criteria, determining an entity’s responsibilities, as well as the condition and appearance of objects, establishes a practically reasonable and scientifically substantiated approach to the perception and understanding of this branch of gemological law. To propose to classify the entities of gemological law, three criteria may be: 1) content and scope of duties; 2) type of gemological activity; and 3) condition and appearance of a gemological object. It is important to note that this classification cannot and should not have strict limits, as entities of gemological relations exhibit inter-group features that manifest in general, group-classified, and direct levels of connections between administrative, mining, and economic relations. The dynamics within these relations can reflect the development and change of one kind of relation to another, along with the accompanying relations.
