Gravastars, theoretical alternatives to black holes, have captured theinterest of scientists in astrophysics due to their unique properties. Thispaper aims to further investigate the exact solution of a novel gravastar modelbased on the Mazur-Mottola (2004) method within the framework of generalrelativity, specifically by incorporating the cloud of strings andquintessence. By analyzing the gravitational field and energy density ofgravastars, valuable insights into the nature of compact objects in theuniverse can be gained. Understanding the stability of gravastars is alsocrucial for our comprehension of black holes and alternative compact objects.For this purpose, we presents the Einstein field equations with the modifiedmatter source and calculate the exact solutions for the inner and intermediateregions of gravastars. The exterior region is considered as a black holesurrounded by the cloud of strings and quintessence, and the spacetimes arematched using the Darmoise-Israel formalism. The stability of gravastars isexplored through linearized radial perturbation, and the proper length, energycontent, and entropy of the shell are calculated. The paper concludes with asummary of the findings and their implications in the field of astrophysics andcosmology.
