About Gold Purity

Here's a breakdown of gold purity:

• Karat System:
  Gold purity is measured in karats (k), where 24k is pure gold (999.9% gold). 

• Common Alloys:
  Common gold alloys include 22k (91.6% gold), 18k (75% gold), 14k (58.3% gold), and 10k (41.7% gold). 

• Durability:
  Lower karat gold (like 14k or 10k) is mixed with other metals (like copper, silver, or nickel) to make it harder and more durable for everyday wear. 

• Appearance:
  The addition of other metals can also alter the gold's color, leading to variations like white gold, rose gold, and yellow gold. 

• Hallmarking:
  In India, the Bureau of Indian Standards (BIS) hallmarks gold to guarantee its purity and authenticity. 

• Investment:
  For investment purposes, higher purity gold (24k or 22k) is preferred due to its higher intrinsic value. 

• Testing:
  Methods to check gold purity include acid testing, X-Ray Fluorescence (XRF) testing, and professional appraisal.
