This dual stamp combines a standard purity fineness mark with the maker's initials. The numeral "925" designates solid sterling silver (containing 92.5% pure silver by weight), while the adjacent "NH" stands for Noble House, the jewelry manufacturing and design firm established by Canadian designer Michael Valitutti, primarily known for his Gems en Vogue collection.

Pieces carrying the "925 NH" stamp are typically substantial, ornate statement rings, pendants, and bracelets. They frequently incorporate multi-gemstone settings, Byzantine- or Renaissance-inspired filigree, pierced undergalleries, and selective 14k or 18k yellow gold-plated accents over solid sterling silver cast mounts.

When examining the interior of a band, look for the letters "NH" struck in block capitals directly beside or beneath "925". This mark should not be confused with standard New Hampshire regional marks or unrelated contemporary makers using NH initials, which typically lack the distinctive, heavy gemstone-set aesthetic and cast undergallery construction of Valitutti's Noble House line.
