هل الجرم السماوي من الذهب الخالص؟

Could you elaborate on the material composition of the orb? Is it indeed crafted entirely from solid gold, or does it incorporate other metals or alloys? If it's gold, is it pure 24 karat, or does it have a lesser purity? Additionally, is there any gemstone or other embellishment embedded within the orb? Furthermore, is the orb hollow, or is its weight indicative of a solid core? Understanding the specifics of the orb's construction is crucial in evaluating its authenticity and potential value.
