Gold Purity Guide: How to Check Hallmark, Carats, and Color Before You Buy

• Gold purity varies, making it crucial to understand hallmarking, carat value, and color to avoid losses.
• A hallmark is an official stamp by BIS in India, confirming gold's purity and authenticity, ensuring it meets government standards.
• Check for BIS Logo, Purity Mark (e.g., 22K/916), Jeweler's Identification Mark, Assaying Center Mark, and Hallmarking Year.
• Carats (K) measure pure gold content: 24K (99.9% pure, soft), 22K (91.6% pure, common for jewelry), 18K (75% pure, for diamond jewelry), 14K (58.3% pure, strong for daily wear), and 10K (41.7% pure, durable).
• Gold color indicates purity and composition: Yellow (natural, higher K), White (gold + palladium/silver), and Rose (gold + copper).
