Understanding Gold Purity: 18K, 22K, and 24K Gold Explained

When buying gold in Kerala, understanding purity levels is crucial for making the right choice. Gold is measured in karats (K), which indicate the percentage of pure gold in the alloy. Let’s explore the different purity levels and their uses.

What is Gold Purity?

Gold purity is measured in karats, with 24K being the purest form. Pure gold (24K) is too soft for jewelry, so it’s mixed with other metals like copper, silver, or zinc to create alloys of different karat values.

Gold Purity Levels Explained

24K Gold (99.9% Pure)

• Purity: 99.9% pure gold
• Characteristics: Bright yellow color, very soft and malleable
• Best For: Investment, gold coins, bars
• Not Ideal For: Daily wear jewelry (too soft, scratches easily)
• Price: Highest price per gram

22K Gold (91.7% Pure)

• Purity: 91.7% gold, 8.3% other metals
• Characteristics: Rich yellow color, durable yet malleable
• Best For: Traditional jewelry, especially in Kerala
• Common Use: Most popular for Indian gold jewelry
• Price: Lower than 24K, higher than 18K

18K Gold (75% Pure)

• Purity: 75% gold, 25% other metals
• Characteristics: Slightly less yellow, more durable
• Best For: Modern jewelry, rings, chains
• Common Use: Contemporary designs, diamond settings
• Price: More affordable than 22K and 24K

Which Karat is Best for You?

For Traditional Kerala Jewelry

22K Gold is the preferred choice because:

• Traditional designs require the malleability of 22K
• Cultural preference for higher purity
• Better resale value in Kerala market
• Suitable for intricate Kerala designs

For Investment

24K Gold is ideal because:

• Pure gold has universal value
• No making charges (for coins/bars)
• Easy to sell anywhere
• Best for long-term investment

For Modern Jewelry

18K Gold works well because:

• More durable for daily wear
• Better for settings with gemstones
• Modern, contemporary designs
• Lower making charges

Understanding Making Charges

Making charges vary by karat:

• 24K: Minimal or no making charges (for coins/bars)
• 22K: Moderate making charges (6-15% typically)
• 18K: Higher making charges (10-20% typically)

Price Calculation

When buying gold jewelry, the total price includes:

1. Gold Rate: Current market rate per gram × weight × purity percentage
2. Making Charges: Percentage of gold value or fixed per gram
3. GST: 3% on gold + making charges

Example for 22K Gold:

• Gold rate: ₹5,838 per gram (22K)
• Weight: 10 grams
• Making charge: 10% = ₹5,838
• Subtotal: ₹64,218
• GST (3%): ₹1,926.54
• Total: ₹66,144.54

Hallmark Certification

Always look for BIS (Bureau of Indian Standards) hallmark certification which guarantees:

• Purity level (22K, 18K, etc.)
• Fineness number (916 for 22K, 750 for 18K)
• Assay center mark
• Year of marking

Tips for Kerala Gold Buyers

1. 22K is Standard: Most Kerala jewelers work primarily with 22K gold
2. Check Hallmark: Always verify BIS hallmark for purity assurance
3. Compare Rates: Check current rates across different districts
4. Understand Making Charges: Negotiate making charges, they’re not fixed
5. Resale Value: 22K and 24K have better resale value than 18K

Common Misconceptions

• Higher Karat = Better: Not always true; depends on your purpose
• 24K is Best for Jewelry: Actually too soft for most jewelry
• All 22K Gold is Same: Purity is same, but quality of alloy metals can vary
• Making Charges are Fixed: They’re negotiable, especially for larger purchases

Understanding gold purity helps you make informed decisions whether you’re buying for investment, traditional occasions, or modern jewelry. Always buy from certified jewelers and verify the hallmark to ensure you’re getting the purity you’re paying for.
