"DNT" on 925 Sterling Silver: Meaning, Benefits, and Care

DNT stands for "Do Not Tarnish." It indicates the chain or component has been coated with a proprietary anti-tarnish layer (often rhodium, lacquer, or nano-ceramic) that slows oxidation and sulfur-induced discoloration.

Benefits

• Keeps jewelry bright longer—months to years vs. weeks for untreated silver.
• Reduces polishing frequency.
• Helpful for sensitive skin (barrier against nickel leaching).

Care Tips

• Store in anti-tarnish pouch or zip-lock bag with silica gel.
• Avoid contact with chlorine, perfume, lotion, sweat.
• Clean gently with a soft microfiber cloth; avoid abrasive polishes that strip coating.

Note: DNT is a treatment, not a purity mark. The 925 stamp still guarantees 92.5% silver.
