Most people in India have bought gold or grown up watching gold being bought, without ever really knowing what the number stamped on it means. The figures like 24K, 22K, 18K, 99.99%, and more, they’re everywhere. They sound important, but they’re rarely explained well.
Basically, they tell you how much of what you’re buying is gold, and how much isn’t.
That distinction sounds simple. But it has real consequences for what you pay, what you’ll get when you sell, and whether the gold you’re holding is actually working for you.
A Brief Comparison of Gold Purity
When most Indians say “gold,” they mean jewellery, and most of that jewellery is 22K gold. The karat number directly determines how much of what you paid is actually gold and how much of it you’ll recover when you sell.
A 22K bangle and a 24K coin bought for the same price do not hold the same gold value. That gap matters more the larger your purchase.
Here’s how the three common gold purities compare across the things that actually affect your money:
| Aspects | 24K (999.9) | 22K (916) | 18K (750) |
| Gold content | 99.99% | 91.67% | 75% |
| Typical use | Investment, digital gold, coins | Indian jewellery, bridal | Designer jewellery, diamond settings |
| Making charges | None (only if held digitally) | ₹300–1,500/g | Higher |
| Resale value | Based on full gold content | Based on pure gold content only | Based on pure gold content only |
| Daily wear durability | Low | Moderate | High |
| Best for accumulation | Yes | Limited | No |

The Karat System
Gold in its natural state is soft. It is too soft to hold its shape in everyday jewellery or for intricate designs. So when gold is used in jewellery, it’s alloyed, mixed with other metals like copper, silver, or zinc, to make it harder and more workable.
Karat measures how much of the final metal is actually gold, on a scale of 24.
- 24K = 24 parts gold out of 24. Essentially pure.
- 22K = 22 parts gold, 2 parts other metals. 91.67% gold.
- 18K = 18 parts gold, 6 parts other metals. 75% gold.
Higher karat means higher gold content. Lower karat means more alloy and a harder, more durable piece.
That’s not a flaw, but it’s all by design.
What Fineness Means
Alongside karats, you’ll see fineness numbers like 995, 999, or 999.9. These measure purity in parts per thousand rather than parts per 24. All three sit within the 24K category, but they’re not identical.
For instance, in 10 grams of gold:
- 995 fineness = 9.95 grams of pure gold
- 999 fineness = 9.99 grams of pure gold
- 999.9 fineness = 9.999 grams of pure gold
The gap sounds marginal. But when you’re accumulating and buying consistently over months and years, those fractions of a gram add up across your total holdings.
More importantly, fineness matters for resale. Investment-grade gold sold on international markets is priced at the highest refinement standards. If you’re holding 995 gold and the benchmark is 999.9, there’s a small but real discount baked in.
SafeGold holds 24K gold at 99.99% purity, the highest commercially available standard, because when you accumulate gold digitally, there’s no reason to accept anything less.
Where Each Karat Actually Makes Sense
- 24K: for accumulation, not adornment
Pure gold is soft. A 24K ring would scratch and deform within weeks of daily wear. That’s why you almost never see 24K jewellery designed to be worn.
But for investment gold coins, bars, and digital gold, 24K is exactly right. You’re holding it. And you want as much actual gold per gram as possible.
- 22K: the Indian jewellery standard
22K gold (also called 916, for its 91.6% purity) is the dominant standard in Indian jewellery. It offers near-pure gold content with enough alloy to withstand the demands of design work, bridal pieces, bangles, and heavy necklaces. It’s why most of the gold your family bought over the years is 22K.
One thing is worth knowing here. When you sell 22K jewellery, the price you’re offered is based on its pure gold content rather than its total weight. The alloy in it doesn’t count. So you’re paying a premium for durability on the way in, but that premium isn’t reflected on the way out.
- 18K: for design, not gold content
18K is 75% gold. It’s chosen when durability and design flexibility matter more than maximising gold content. For diamond-studded pieces, international designer jewellery, and coloured gold (rose gold, white gold), 18K is the standard because the alloy can be manipulated more freely.
If accumulating gold is the goal, 18K is the least efficient way to do it. You’re paying for workmanship and design.
The Hidden Cost Most People Don’t Calculate
Here’s where the investment angle becomes genuinely important.
When an Indian family buys 22K jewellery, they typically pay:
- The gold rate (at 22K purity)
- Making charges (₹300–₹1,500 per gram, sometimes more for intricate designs)
- 3% GST on gold value + 5% GST on making charges
When they sell that same jewellery back, they receive:
- A price based on the pure gold content (the 22K rate that day)
- No credit for making charges
- Sometimes, a small deduction for “testing” or “melting.”
The making charges are gone completely. You paid them, and they don’t come back.
With 24K digital gold, there are no making charges. You buy gold at the live market rate, and when you sell, you sell at the live market rate. The spread exists; that’s how any traded asset works, but you’re not carrying a permanent cost that never recovers.
This is the real reason purity matters for accumulation. It’s about the total cost structure of how you hold gold.
How to Know What Purity You’re Actually Getting?
For physical jewellery, BIS hallmarking is the regulatory standard in India. Since September 2021, hallmarking is mandatory for 14K, 18K, and 22K gold jewellery. Each piece carries a six-digit HUID (Hallmark Unique Identification) number that you can verify on the BIS Care app.
For digital gold, purity is a structural guarantee.
SafeGold’s gold is stored by Brinks, a professional vault operator, and held under an independent trustee structure (with Vistra as the administrator). It’s separate from the platform’s corporate assets and delivered as assay-certified coins upon physical redemption. See delivery steps here.
So Which Purity is Right For You?
If you’re buying to wear for a wedding, a festival, or a gift, 22K is the right call for most traditional pieces. It’s how jewellery gold has always worked in India, and it works well for that purpose.
If you’re buying to accumulate, to build a gold position over time, to hold value, to eventually convert into coins or jewellery when you choose, 24K is the only purity that makes complete sense. You get the most gold per gram, no making-charge overhead, and full liquidity to sell at any time at the live rate.
The mistake most people make is using the same purchase logic for both goals. Jewellery and accumulation are different activities. Gold is the common thread, but the buy structure is completely different.
Know what you’re buying gold for and then choose accordingly.
Conclusion
Gold has appreciated nearly 100% in India over the past year alone. Whether you’re a long-term accumulator or someone who just inherited jewellery and is now thinking more carefully about it, understanding what purity you hold, and what that means for your actual position, is not a small thing.
It’s the difference between owning gold and owning the idea of gold.

FAQs
Q. If I buy 22K jewellery and gold prices double, do I gain the full benefit?
A. Not entirely. Your resale is calculated on the pure gold content (91.67%), not the total weight you paid for. The making charges you paid upfront don’t appreciate with the gold price.
Q. Does higher fineness, say 999.9 vs 999, actually change what I earn when I sell?
A. Yes, marginally but measurably, especially if you’re holding large quantities over time. International bullion benchmarks at 999.9, so anything below that can attract a small discount at redemption.
Q. Can I convert my SafeGold holdings into 22K jewellery even though the vault holds 24K?
A. Yes, through partners like Tanishq, your 24K digital holdings can be redeemed into jewellery. The conversion to 22K occurs at that stage; what you hold digitally remains pure until you choose to act on it.
Q. Is there any point in buying 18K gold purely as a financial asset?
A. Practically, no. 25% of what you’re paying for isn’t gold, and that portion doesn’t appreciate when gold prices rise. 18K makes sense for design; it doesn’t make sense as an accumulation strategy.
Q. Why do jewellers quote the “gold rate” but the final bill is always much higher?
A. The gold rate covers only the raw material. When charges, wastage, and GST are stacked on top of each other, they can add 15–25% to your total cost. That gap is what you avoid entirely when you buy gold digitally at the live market rate.
