In quantum mechanics and particle physics, Spin is considered as an intrinsic form of the quantum orbital angular momentum. The goal of this paper is to demonstrate that in accordance with the creative original idea of Kronig, Uhlenbeck and Goudsmit, Spin can be represented as an intrinsic form of quantum Spherical Top angular momentum. It will be shown that this internal symmetry can be realized on a set of the simplest geometrical quantities, which themselves do not exhibit this emergent property. That is why this phenomenon will be called Emergent Spin. The concept of Spin as an emergent property is more general than the habitual concept of Spin and, hence, it can be interesting in terms of discussion of possible ways to look for a physics beyond the Standard Model. Now, there is no doubt that new physics really exists and we need clear guidance on the best place to look.
