Quick Answer
Compare 999, 925, and 900 silver purity for Indian buyers, including BIS hallmarking, resale value, jewellery use, coins, and gifting.
Walk into any jewellery store in India — whether it is a family-run shop in Jaipur's Johari Bazaar or a branded showroom in a Mumbai mall — and you will hear numbers thrown around: 999, 925, 900. The shopkeeper says them with confidence, but most buyers nod along without truly understanding what those numbers mean for their money.
If you have ever found yourself in that situation, this guide is for you. We will break down every silver purity grade you are likely to encounter, explain how BIS hallmarking protects you, and compare use cases across investment, jewellery, and gifting. By the end, you should know which purity fits your specific need — whether you are buying a 10-gram coin for Dhanteras or a set of silver glasses for a housewarming gift.
Silver purity is measured in parts per thousand. When someone says "999 silver," they mean that out of every 1,000 parts, 999 are pure silver and only 1 part is trace metal. Here is how the three common grades compare:
| Purity Grade | Pure Silver Content | Other Metals | Common Names | Primary Use in India |
| ------------ | ------------------- | --------------------- | ------------------------------ | --------------------------------------------------- |
| 999 | 99.9% | 0.1% trace | Fine silver, three-nine silver | Investment coins, bullion bars, religious offerings |
| 925 | 92.5% | 7.5% (usually copper) | Sterling silver | Jewellery, cutlery, decorative items |
| 900 | 90.0% | 10% (copper, zinc) | Coin silver | Vintage coins, some traditional utensils |
The remaining percentage matters more than you might think. Those 7.5% or 10% of added metals change the silver's hardness, colour, tarnish resistance, and — most importantly — its resale value.
ℹ️
Note
The Bureau of Indian Standards (BIS) currently recognises three grades for hallmarking: 999, 970,
and 925. If you see silver stamped "900" in a shop, it is not BIS-hallmarkable under current
rules. Always look for the BIS hallmark triangle and the purity number together.

Fine silver at 99.9% purity is the benchmark for investment-grade silver worldwide — and in India, it is the standard used by mints, banks, and platforms like Vittarq for coins and bars.
Transparent pricing. The silver spot price that you see on news tickers (currently around ₹95,000 per kilogram) refers to 999-purity silver. When you buy a 999 coin, the math is straightforward: spot price plus making charge plus GST. There is no guessing game about how much actual silver content you are paying for.
Universal acceptance. Any jeweller in India — from Tanishq to your neighbourhood goldsmith — will accept BIS-hallmarked 999 silver at its full weight for exchange or sale. With lower purities, the jeweller may apply a "purity deduction" before quoting a price, which quietly erodes your return.
Better resale value. Because 999 is the globally traded standard, your coins hold their value better over time. A 50-gram 999 silver coin bought in Chennai is worth exactly the same in Delhi, Kolkata, or Ahmedabad — the purity is not in question.
Fine silver is softer than sterling. If you press your thumbnail firmly into a 999 coin, you might leave a faint mark. This is why 999 is ideal for items that are stored and held — coins, bars, small bullion — rather than items that are worn daily.
Real-world example: A family in Pune buys five 10-gram 999 silver coins as Dhanteras gifts for their nieces and nephews. Total silver cost: approximately ₹4,750 (at ₹95/gram). With Vittarq's flat ₹350 making charge per coin and 3% GST, total outlay is about ₹6,700. Each coin is BIS-hallmarked, comes with HUID, and can be sold to any jeweller in India at full 999 purity value.
Sterling silver — 92.5% pure — is the global standard for wearable silver. The 7.5% copper alloy makes it significantly harder and more durable than fine silver, which is why virtually all silver jewellery you see in stores is 925.
While 925 silver is perfectly good material, it carries an overlooked cost for investors. When you eventually sell or exchange a 925 piece, the buyer (whether a jeweller or a platform) will value only 92.5% of its weight as silver. On a 100-gram necklace, that means 7.5 grams of your "silver" is actually copper — and copper is worth virtually nothing in comparison.
Additionally, 925 jewellery typically carries much higher making charges than coins. A 30-gram sterling silver necklace might cost ₹4,500-6,000 at a jeweller, but the actual silver content is only about 27.75 grams — worth roughly ₹2,600 at spot. The rest is making charge, brand premium, and GST. If you sell it back, the jeweller will pay you for 27.75 grams of silver content, minus a small deduction.
| Factor | 999 Silver Coin | 925 Silver Jewellery |
| ----------------------- | -------------------------- | ---------------------------------- |
| Silver content per 100g | 99.9g | 92.5g |
| Resale value basis | Full weight at spot | 92.5% weight at spot |
| Making charges | Low (₹350 flat at Vittarq) | High (varies by design complexity) |
| Wearability | Not meant for wearing | strong for daily wear |
| BIS hallmark available? | Yes | Yes |
You are unlikely to encounter 900-purity silver in modern retail. It was historically used for coinage (the term "coin silver" comes from this grade) and some traditional Indian utensils. If you find 900 silver today, it is usually in:
Antique coins from the British Raj or pre-independence princely states
Vintage utensils inherited within families
Some temple offerings in specific regional traditions
For collectors and history enthusiasts, vintage 900 silver pieces have numismatic value that goes beyond their metal content. A British-era one-rupee coin in good condition might sell for ₹500-5,000 depending on rarity — far more than its silver melt value.
However, for investment purposes, 900 silver has no advantage over 999. It contains less silver per gram, is harder to verify without testing, and most modern jewellers will not accept it at face value without an assay.
⚠️
Warning
Be cautious if a seller offers you "90% pure silver" as an investment product at a price close to
999 rates. You are getting 10% less silver per gram. Always verify the BIS hallmark and purity
stamp before purchasing.
Before HUID, it was possible (and common) for unscrupulous sellers to stamp purity marks on sub-standard silver. The HUID system creates a traceable link between the physical article and the lab-tested purity record. When you sell or exchange a HUID-stamped coin at any jeweller in India, there is no argument about purity — the number proves it.
Key Takeaway
For any silver purchase where value retention matters — investment coins, gifts meant to be saved,
or high-value utensils — insist on 999 purity with a BIS hallmark and HUID. For wearable
jewellery, 925 sterling with BIS hallmark is the right choice. Avoid 900 purity unless you are
buying for collectible value.
Let us say you have ₹10,000 to put into silver today. Here is how the purity choice affects your position five years later, assuming silver appreciates 8% annually (its rough average over the past decade):
| Metric | 999 Coin (Vittarq) | 925 Jewellery (Jeweller) |
| --------------------------------- | ------------------ | --------------------------------------------- |
| Amount spent | ₹10,000 | ₹10,000 |
| Making charges | ₹350 (flat) | ~₹2,500 (25% of price) |
| Actual silver bought | ~101g at ₹95/g | ~82g (after making charges + purity discount) |
| Silver value in 5 years (8% CAGR) | ~₹14,150 | ~₹11,480 |
| Net return | ~41.5% | ~14.8% |
The difference is stark. Higher making charges and lower purity eat into your returns before the silver price even moves. This does not mean 925 jewellery is a bad purchase — it serves a completely different purpose. But if your goal is wealth preservation or investment, 999 coins are the only logical choice.
| Your Goal | Best Purity | Why | Where to Buy |
| -------------------------- | ----------- | ---------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------- |
| Long-term investment | 999 | Maximum silver content, lowest making charges, universal resale | Platforms like Vittarq, bank branches, authorised mints |
| Festival gifting (coins) | 999 | Beautiful, valuable, and the recipient gets maximum silver value | Vittarq, jewellers, bank counters |
| Daily-wear jewellery | 925 | Durable enough for regular wear, widely available in beautiful designs | Your trusted jeweller (Tanishq, Malabar, local artisans) |
| Wedding gifting (utensils) | 925 or 999 | 925 for items that will be used; 999 for items that will be displayed/stored | Jewellers for utensils, Vittarq for coins in gift boxes |
| Vintage collecting | 900 | Historical and numismatic value beyond metal content | Antique dealers, numismatic societies, auction houses |
One category that often gets overlooked is gift boxes. A beautifully packaged silver coin inside a premium gift box — whether for Diwali, a baby's naming ceremony, or a corporate Dhanteras gift — combines the investment value of 999 silver with the emotional impact of thoughtful presentation. The coin retains its full resale value; the gift box adds the experience. It is a combination that works beautifully for both personal and corporate gifting.

Tip
When gifting silver coins for occasions like Dhanteras, Akshaya Tritiya, or weddings, always
choose 999 purity. The recipient gets a gift they can cherish and one that grows in value. Pair it
with a gift box for the full experience.
Every silver coin on Vittarq is 999-purity, BIS-hallmarked with HUID, and carries a flat ₹350 making charge regardless of weight. Whether you buy a 5-gram coin or a 100-gram coin, the making charge stays the same — which means the per-gram cost advantage improves dramatically as you buy larger weights.
This flat-fee model is fundamentally different from the percentage-based making charges common in the jewellery industry (where making charges can range from 8% to 25% depending on the item and the store). For silver coins specifically, the flat-fee approach keeps costs transparent and predictable.
Buying 925 for investment. Sterling silver is beautiful for jewellery but costs you 7.5% of your silver content upfront — money you never recover.
Ignoring making charges. A ₹350 flat charge on a 50-gram coin is 0.7% of the silver value. A 15% making charge on jewellery is over 20x more expensive in relative terms.
Not checking the BIS hallmark. Without it, you have no guarantee of purity. The HUID number is your insurance policy.
Comparing prices without comparing purity. A "cheaper" 925 piece is not cheaper once you account for the 7.5% purity difference.
Overlooking silver entirely. Many Indian families default to gold for every occasion. Silver coins and gift boxes offer strong value, especially for festivals and milestone gifts.
Yes, 999 fine silver is softer than 925 sterling silver and is not recommended for rings,
bracelets, or items that experience daily friction. However, it is perfect for coins, bars, and
stored items where softness is not a concern. The slight softness is actually a sign of high
purity — it means there are almost no hardening alloys mixed in.
Can I exchange a 999 silver coin at any jeweller in India?
Yes, provided the coin carries a BIS hallmark and HUID. Under current regulations, any
BIS-registered jeweller must accept hallmarked silver at its stated purity for exchange or
purchase. The HUID number allows the jeweller to verify purity instantly through the BIS Care app,
so there is no argument or negotiation about content.
How do I verify the BIS hallmark on a silver coin?
Download the BIS Care app (available on Android and iOS). Enter the six-digit alphanumeric HUID
code stamped on the coin. The app will display the registered purity, weight, and the assaying
centre that tested the article. If the HUID does not return results, the hallmark may be
fraudulent — do not complete the purchase.
Is silver a good investment compared to gold?
Silver and gold serve different roles in a portfolio. Silver is more affordable per gram, has
higher industrial demand (electronics, solar panels, medical devices), and historically shows
larger percentage swings in bull markets. Gold is the traditional safe haven. Many financial
advisors recommend holding both — see our silver-gold ratio
guide for a framework on when to favour which metal.
Why does Vittarq only sell 999 silver coins and not 925?
Because Vittarq's coins are designed for investment and value retention, not for wearing. At 999
purity, every gram you buy is virtually pure silver with maximum resale value. If you want
beautiful wearable silver jewellery, your local jeweller is a strong choice for 925 sterling
pieces — and your 999 Vittarq coin will always be there as a store of value alongside your
jewellery collection.
