What Does KDM Gold Mean for Investment? Unpacking Its Market Value
As an investment, KDM gold is valued on its gold content alone: measured purity multiplied by net weight at the live rate. The KDM label adds nothing and takes nothing away. Most KDM-era ornaments were bought when 24K gold cost between about ₹4,400 and ₹48,000 per 10 grams, so the gold inside them has grown roughly 3 to 34 times. Making charges were never an investment and do not come back. Held for more than 24 months, gains on sale are taxed at 12.5% without indexation.
Families across Durgapur, Asansol and Bankura hold a surprising amount of wealth in ornaments bought during the KDM years, roughly the late 1980s to the mid-2010s. They were bought for weddings and festivals, not as a portfolio. But thirty years later, that jewellery often turns out to be the best-performing asset the household owns. This guide looks at KDM gold purely as an investment: what it is worth, how that value is measured, what eats into it, and when it makes sense to convert it.
The Investment Value of KDM Gold Comes From One Thing
An investor in gold owns grams of fine gold. Everything else, such as the design, the stamp, the shop's name and the solder used to join it, is packaging. KDM describes packaging. When a KDM ornament is valued as an asset, the calculation is the same as for a coin or bar:
Value = live 24K rate per gram × measured purity × net gold weight. At Auriksha, the payout is that figure less a fixed 2% margin and a 1% dust-and-wax deduction, and nothing else.
Two consequences follow. First, a KDM stamp cannot make a piece worth more than its tested purity, even if the family always believed it was "pure 22K". Second, the absence of a hallmark cannot make it worth less. The assay decides the value, not the label.
How Much Has KDM-Era Gold Actually Grown?
The table below takes a 20-gram, 22-carat ornament and compares the value of its gold content in the year it was bought with its value on 25 September 2026, when the 22K base rate stood at ₹13,667 per gram. Historic figures are approximate annual averages for 24K gold, converted to 22K content.
| Year bought | Approx. 24K rate (per 10 g) | Gold value of 20 g 22K then | Same gold on 25 Sep 2026 | Growth |
|---|---|---|---|---|
| 2000 | ₹4,400 | ≈ ₹8,060 | ₹2,73,340 | ≈ 34× |
| 2005 | ₹7,000 | ≈ ₹12,820 | ₹2,73,340 | ≈ 21× |
| 2010 | ₹18,500 | ≈ ₹33,890 | ₹2,73,340 | ≈ 8× |
| 2015 | ₹26,340 | ≈ ₹48,260 | ₹2,73,340 | ≈ 5.7× |
| 2020 | ₹48,650 | ≈ ₹89,130 | ₹2,73,340 | ≈ 3× |
The comparison is gold content to gold content. The price originally paid at the counter was higher than the "then" column because it included making charges and, later, GST. Those were costs of buying jewellery, not part of the investment, which is why a resale offer never matches a receipt.

Three Things That Quietly Reduce a KDM Ornament's Value
1. Purity drift from the declared karat
Before hallmarking was compulsory, many shops sold 22K ornaments that actually assayed at 21K or a little below. Ironically, cadmium solder is the reason many KDM pieces test well: it kept joints high in gold. Pieces from lesser workshops, however, may read closer to 88% than 91.6%. On 20 grams, that gap is worth more than ₹10,000 at today's rates. It is worth knowing before you plan around a number.
2. Non-gold weight
Old Bengali ornaments are often hollow and filled with lac, or set with stones, glass or enamel. None of that weight is gold. An honest valuation deducts it; a careless one pays for it at the gold rate and then recovers the difference with a lower rate.
3. The exit route you choose
The same ornament can fetch noticeably different amounts depending on whether it is exchanged at a jewellery counter, pledged, or sold outright to a buyer who prices on the live rate. For an investor, the exit route is part of the return.
KDM Jewellery vs Coins vs Bars as an Investment
| Form | What you paid for beyond gold | Resale basis | Best use |
|---|---|---|---|
| KDM-era ornament | Making charges, wastage, stones | Measured purity × net weight | Wear, heirloom, or convert when needed |
| Hallmarked 22K jewellery | Making charges + GST | Measured purity × net weight | Wear first, store of value second |
| 24K coin or bar | Small premium + GST | Measured purity × weight | Pure savings; lowest cost to buy and sell |
If an ornament is no longer worn, keeping it as an ornament holds no investment advantage over holding the same grams as a coin or a bar. What decides whether to keep it is sentiment and need, not market value, because the gold grows at the same rate in any form.

Tax on Selling KDM Gold
Physical gold, including jewellery, held for more than 24 months counts as a long-term capital asset. For sales made after 23 July 2024, the long-term gain is taxed at 12.5% without indexation. Gains on gold held for 24 months or less are added to your income and taxed at your slab rate. For inherited gold, the previous owner's holding period and purchase cost carry over to you, so most inherited KDM ornaments qualify as long-term. Keep your sale invoice, and speak to a tax adviser if the amount is significant.
Hold, Exchange or Sell? A Simple Test
- Is the piece still worn or emotionally important? If yes, hold it. The gold inside keeps pace with the market regardless.
- Is it lying unused in a locker while you pay locker rent or insurance? Its return is being taxed by storage costs, so converting to a smaller coin or selling is reasonable.
- Do you need money for a specific purpose, such as education, a medical bill or clearing a costly loan? Selling at a fair live-rate valuation is usually cheaper than borrowing against it at interest.
- Are you replacing it with new jewellery? Get a sale valuation before you accept an exchange offer, so you can compare the two numbers directly.
