When you buy gold in India — whether as jewellery, coins, or digitally — the purity matters enormously. Yet most buyers don't fully understand what "karat" or "fineness" actually means.

What is Karat?

Karat (k) measures the proportion of pure gold in an alloy, on a scale of 24. So:

  • **24k gold** = 99.9% pure gold (also written as 999 or 999.9)
  • **22k gold** = 91.6% pure gold (also written as 916)
  • **18k gold** = 75% pure gold (also written as 750)
  • The remaining percentage is made up of other metals like silver, copper, or zinc, which add hardness and colour.

    Why Does Purity Matter?

    For investment purposes, higher purity = higher value. When you sell, buyers assess purity. 24k gold commands the best resale value because there's no alloy to discount.

    For jewellery, 22k is common because pure gold (24k) is too soft and can bend easily. But for coins, bars, and digital gold? 24k is always preferred.

    What is 999.9 Fineness?

    The global standard for investment-grade gold is 999.9 fineness — meaning 99.99% pure. This is what you get with digital gold on platforms like Sana Gold, stored in LBMA-compliant vaults.

    The Takeaway

    If you're buying gold to save and invest, always go for 24k / 999 purity. That's what Sana Gold offers — and it means your savings hold maximum value.
