Gold Purity Basics
Gold purity is measured in karats, with 24 karat being pure gold. Because pure gold is too soft for most jewellery, it is alloyed with metals like copper, silver, or zinc. The karat number tells you the percentage of gold: 18 karat contains 75% gold, 14 karat contains 58.3%, and 10 karat contains 41.7%. Lower karat pieces are more durable but contain less gold.
Understanding this scale is critical for investment. A 24 karat gold bar holds more gold value than an 18 karat ring, but the ring may have higher craftsmanship value. Always check the karat stamp on the item. Common stamps include 24K, 22K, 18K, 14K, and 10K. In some countries, you might see a three-digit number like 750 for 18 karat.
How to Verify a Hallmark
A hallmark is a official mark that guarantees purity. In many countries, a hallmark includes the maker’s mark, the fineness (e.g., 750 for 18K), and an assay office mark. Look for a small stamp inside rings, on clasps of necklaces, or on the surface of bars. If you cannot find a stamp, the item may not be certified. Reputable sellers like Solanki Jewellers provide items with clear hallmarks.
To verify a hallmark, you can check the assay office’s online database or use a simple magnifying glass. Some pieces also include a year letter. For gold coins and bars, look for a certification card or a serial number. Hallmarks protect you from buying lower purity gold at higher prices.
Step-by-Step: Check Gold Purity Yourself
Step 1: Locate the Stamp
Use a jeweller’s loupe or a strong magnifying glass. Examine the piece for any numbers or letters. Common stamps are 585 (14K), 750 (18K), 916 (22K), and 999 (24K). If there is no stamp, the piece is likely not certified.
Step 2: Perform a Magnet Test
Gold is not magnetic. Use a strong neodymium magnet. If the piece sticks to the magnet, it contains ferrous metals and is not pure gold. This test works best for gold bars and coins. For jewellery, complex clasps may contain small steel springs, so test only the main body.
Step 3: Use a Testing Kit
Purchase an acid testing kit from a jewellery supply store. Scratch the gold on a testing stone, apply a small drop of acid corresponding to different karats. If the scratch dissolves, the purity is lower than the acid’s karat rating. For example, 18K acid will not dissolve 18K gold but will dissolve 14K gold.
Step 4: Check Weight and Dimensions
Weigh the item on a precision scale. Compare its weight to standard dimensions for that type of piece. A gold bar should match the expected weight exactly. For jewellery, this is less reliable because of design variations, but extreme lightness may indicate hollow construction or lower density.
Expert Tip: Always test in an inconspicuous area. For investment bars, do not scratch the surface—use an electronic gold tester instead. Many buyers prefer to have a professional jeweller verify before purchase.
What Determines Investment Value
The investment value of gold depends on four factors: purity, weight, market price, and liquidity. Pure gold (24K) at 1 gram is worth the spot price multiplied by its weight. But at Solanki Jewellers, you also pay a small premium for craftsmanship and certification. When selling, you will receive the melt value minus any refining fees.
Gold coins and bars from recognized mints hold higher resale value than jewellery. Jewellery value includes design and labour, which is usually lost on resale. If your primary goal is investment, buy 24K bars or coins. If you want wearable jewellery that retains some gold value, 22K is a good compromise.
Gold Prices by Karat
| Karat | Gold Content | Typical Use | Resale Value (per gram) |
|---|---|---|---|
| 24K | 99.9% | Investment bars, coins | Spot price × 0.999 |
| 22K | 91.7% | High-end jewellery | Spot price × 0.917 minus 5-10% |
| 18K | 75.0% | Fine jewellery | Spot price × 0.75 minus 10-20% |
| 14K | 58.3% | Everyday jewellery | Spot price × 0.583 minus 15-25% |
| 10K | 41.7% | Durable costume | Spot price × 0.417 minus 20-30% |
Buying Tips
- Compare total cost: Always ask for the final price including making charges and taxes. Some sellers add high making charges that reduce investment value.
- Check buyback policy: Solanki Jewellers often offers buyback at current market rates. Confirm this before purchase.
- Prefer hallmarked pieces: In many countries, hallmarking is mandatory. Avoid non-hallmarked gold for investment.
- Understand premiums: Coins and bars from mints like PAMP or Perth Mint have premiums around 2-5% over spot. This is normal and covers certification and packaging.
Troubleshooting Common Concerns
I Lost the Hallmark Stamp
A stamp can wear off over time, especially on rings. Take the piece to Solanki Jewellers or another certified jeweller for electronic testing. They can verify purity and re-stamp if needed.
My Gold Looks Discoloured
Discolouration usually comes from alloy metals reacting with chemicals. It does not necessarily mean low purity. Have it tested. Pure gold rarely discolours, but 14K and lower can show tarnish.
I Paid Above Spot Price
Paying above spot is normal for jewellery and small bars. Compare with current market rates. If you paid more than 30% above spot for a bar, you may have overpaid. For jewellery, making charges vary widely.
Is 10K Gold a Good Investment?
10K gold is the least valuable per gram. Its investment potential is low because high alloy content reduces gold value. It is best for affordable, durable jewellery, not for building wealth.
Frequently Asked Questions
How can I tell if my gold is real without a test kit?
Check for a hallmark stamp. Most real gold items have a karat stamp. Use the magnet test: real gold is not magnetic. Also look for discolouration at edges. If it leaves a black mark on ceramic, it is likely fake.
What does 585 mean on gold?
585 means 58.5% gold content, which is 14 karat. It is a common European marking. This stamp indicates the item contains 14 parts gold and 10 parts other metals.
Does Solanki Jewellers buy back gold?
Yes, most reputable jewellers including Solanki Jewellers offer buyback services. They pay based on current market price minus a small refining fee. Always ask for their buyback rate before purchasing.
Is 22K gold suitable for daily wear?
22K gold is softer than 18K or 14K. It can scratch and bend if worn daily, especially in rings and bracelets. It is better for special occasions or as a store of value rather than everyday jewellery.
How much gold should I buy for investment?
Start with a small portion of your portfolio, around 5-10%. Buy 1 gram or 10 gram bars from trusted sources. You can also buy gold coins. The goal is to have a liquid asset that holds value over time.
Final Checklist Before Buying

Conclusion
Evaluating gold purity and investment value comes down to three things: check the hallmark, test if you can, and compare the full price including premiums. Use the step-by-step guide to verify any piece before buying. Focus on hallmarked gold from sellers like Solanki Jewellers who provide clear information. For investment, prefer 24K or 22K bars. For jewellery, accept lower purity but understand the resale hit. Trust your verification methods and buy from sources with transparent pricing.
