925 Gold Meaning
In fine jewelry manufacturing, precious metals assaying, and silversmithing, the stamp '925' (or 'S925', 'Sterling', 'Ster') is the universally recognized hallmark certifying that the piece is forged from authentic Sterling Silver, containing exactly 92.5% pure elemental silver alloyed with 7.5% other strengthening metals (almost exclusively pure copper). This 925 ratio represents the world's most prestigious and durable metallurgical standard for fine silver jewelry, luxury flatware, and hollowware.
