    Silver Tarnishing: Why It Happens & How to Prevent It

    Silver naturally reacts with sulfur in the air, forming silver sulfide (Ag©üS), which appears as a dark layer on the surface.

     

    🔹 How to Prevent Tarnishing

     Store silver in anti-tarnish bags or cloth

     Keep away from sulfur-rich environments (rubber, wool)

     Clean with a silver polishing cloth regularly

    Synthetic Diamonds: Are They Real?

    Yes! Synthetic diamonds are real diamonds but are made in a lab rather than naturally formed in the Earth.

     

    🔹 Types of Synthetic Diamonds

    -- HPHT (High-Pressure High-Temperature) – Mimics natural formation

    -- CVD (Chemical Vapor Deposition) – Grows diamonds layer by layer

     

    🔹 How Are Synthetic Diamonds Different from Natural Ones?

     

    Same chemical and physical properties

    Lower cost (typically 20-40% cheaper than mined diamonds)
