Diamonds vs Gold: Which Is the Better Investment Option?

• Gold offers better liquidity compared to diamonds.
• Resale value of diamond vs gold favours gold as a long-term asset.
• Diamonds are harder to liquidate due to their specific characteristics.
• Gold provides a safer and more transparent investment avenue.

Jewellery has always been an integral part of Indian households, especially gold, symbolising wealth, status, and tradition. Over the years, gold has been a preferred asset class for both personal adornment and investment purposes. However, diamonds are increasingly making their presence felt, not just as a luxury accessory, but also as a potential investment. At Aditya Birla Capital, we believe it is important to carefully evaluate both asset classes before making a decision. On that note, let’s break down the key aspects of diamond vs gold investment, helping you choose the best option based on facts, financial goals, and market dynamics.

So which one actually makes sense as an investment? For most Indian investors, gold offers superior liquidity, price transparency, and regulated investment formats compared to diamonds. Diamonds can preserve their value over the long term, but they lack an organised resale market in India, making them a better fit for collectors than for those simply trying to grow their savings.

Before you put your money into either one, it helps to look past the emotional pull and weigh the numbers: liquidity, taxation, resale value, and how each asset actually behaves once gold rates swing or a diamond needs to be sold in a hurry.

Gold enjoys an established global market with regular trading practices, making it highly liquid. You can sell gold jewellery, coins, or bars at any recognised jewellery store or exchange with minimal hassle. Gold holds historical importance as a stable investment that appreciates over time and protects against inflation and market volatility.

Here's a sense of scale:

As of 23 June 2026, 24-karat gold was trading around ₹14,591 per gram, roughly ₹1,45,910 for 10 grams. Gold had already touched an all-time high of ₹1,78,850 per 10 grams (24K) on 29 January 2026 before pulling back.

Whatever the day-to-day number, the broader pattern is clear: gold in India has moved from under ₹100 per 10 grams in the 1960s to well past ₹1.4 lakh today, i.e., 23rd June 2026, riding through every major economic shock along the way.

In terms of how you can actually invest, gold in India comes in several shapes: physical gold (jewellery, coins, and bars); gold ETFs; gold mutual funds; and digital gold. There's one important catch worth flagging here: the Sovereign Gold Bond (SGB) scheme, which used to sweeten the deal with an extra 2.5% annual interest, isn't open to new investors any more. RBI hasn't issued a fresh tranche since February 2024, and the government has confirmed, most recently around the Union Budget 2025 announcements, that there's no plan to restart it.

If you already hold SGBs, you can still wait till maturity or redeem early after five years. If you don't, the only way in is to buy existing series on the NSE or BSE.

• Standardised pricing by purity and weight makes valuation straightforward.
• High liquidity; sellable at almost any jeweller, bank, or bullion exchange, often the same day.
• Several regulated formats to choose from: Gold ETFs, gold mutual funds, and digital gold.
• A long track record as an inflation hedge and a safe-haven asset during uncertain times.
• No counterparty risk when you hold physical gold or bullion-backed ETFs outright.

• Physical gold needs storage and insurance, and theft is a genuine worry for many households.
• No regular income from holding physical gold, since the SGB interest option is now closed to new buyers.
• Making charges on jewellery, typically taxed at 5% GST on top of the retailer's margin, quietly eat into your real returns.
• Import duty on gold jumped from 6% to 15% (10% basic customs duty plus 5% agriculture infrastructure cess) with effect from 13 May 2026, which can push up the landed cost of fresh purchases.

Diamonds, on the other hand, do not have a standard global market in the same way gold does. Each diamond is unique, and its resale value depends on characteristics such as cut, clarity, carat, and colour. This makes liquidating diamonds more complicated and time-consuming.

Diamonds are graded on what's known as the 4Cs: Carat, Cut, Clarity, and Colour, and no two stones are graded quite the same way. Unlike gold, there's no daily spot price you can check before walking into a shop, which makes honest price discovery tough for an ordinary buyer.

GIA or IGI certification goes some way toward resolving the problem by confirming a stone's authenticity and quality on paper, though a certificate still doesn't promise you'll find a buyer when you actually want to sell.

Wholesale prices for lab-grown stones fell by roughly 20-30% between 2023 and 2025, though the rate of decline has slowed to around 5-8% a year in 2025-26 as manufacturing costs are there; figures echoed across multiple industry pricing trackers.

The knock-on effect is real: natural diamonds typically hold on to 40-60% of their purchase price at resale, while lab-grown stones often fetch just 20-40%, per resale. There's also a new layer of regulation to be aware of; in January 2026, the Bureau of Indian Standards (BIS) began enforcing standard IS 19469:2025, which requires that the company reserve the word "diamond" for natural stones only and requires that lab-grown diamonds be clearly labelled as such to prevent misleading buyers at the counter.

• Diamonds are far easier to store and carry than an equivalent amount of value in gold.
• Genuinely rare, high-quality natural stones tend to hold their price better than average-quality diamonds.
• Exceptional or coloured diamonds can appreciate significantly at auction.
• Diamonds are the hardest known natural substance, so unlike gold jewellery, they don't wear down or scratch with everyday use.

• Low liquidity is the single biggest drawback; there's no organised market for reselling individual diamonds in India.
• Pricing isn't transparent.
• Retail markups from making charges and dealer margins can be steep, sometimes reaching 30-50% over the wholesale value.
• Without proper certification, authenticating a stone is genuinely challenging, which adds risk for both buyer and seller.
• Continued growth in lab-grown diamond supply continues to weigh on resale prices across the category, including natural stones.

Resale value of diamond vs gold tends to favour gold because of consistent market demand and minimal intermediaries. Diamonds typically face lower resale returns due to significant retailer markups and the need for specific buyer interest. Gold is also far more fungible; you can easily exchange gold bars or coins for others of the same type, weight, and purity, while diamonds can only be exchanged for stones with near-identical characteristics.

• Physical gold and digital gold: if you sell within 24 months of buying, the gain counts as short-term and is taxed at your income slab rate. Hold it longer than 24 months, and the gain becomes long-term, taxed flat at 12.5% with no indexation benefit.
• Gold ETFs and gold mutual funds: follow the identical STCG/LTCG structure as physical gold, i.e., 12.5% LTCG without indexation past 24 months and slab-rate STCG before that.
• Sovereign Gold Bonds (SGBs): if you were an original RBI subscriber and you hold your bond all the way to its 8-year maturity, the capital gains exemption still applies in full. But from 1 April 2026, Budget 2026 tightened this; anyone who bought their SGB on the secondary market (NSE or BSE, rather than directly from the RBI) now pays 12.5% LTCG if held for over 12 months or slab-rate STCG if sold sooner. The 2.5% annual interest, by the way, has always been taxable at your slab rate for every holder, and that part hasn't changed.
• Diamonds: treated as capital assets under the Income Tax Act, just like gold. Sell within 24 months, and you pay slab-rate tax on the gain; hold beyond 24 months, and it's a flat 12.5% LTCG with no indexation.
• GST on purchase: physical gold and gold jewellery attract 3% GST on the gold's value (split as 1.5% CGST and 1.5% SGST), plus a separate 5% GST on making charges. Gold ETFs and gold mutual funds skip GST on the underlying gold entirely, though fund-management or service charges can attract 18% GST.

Gold is widely regarded as a safe investment, especially during economic downturns. Moreover, its authenticity is easier to verify with recognised hallmark stamps. With the advent of lab-grown diamonds, verifying the purity and authenticity of natural diamonds becomes challenging. This lack of transparency makes gold a safer choice for long-term investments.

Gold is far more fungible than diamonds. You can easily exchange gold bars or coins for others of the same type, weight, and purity, ensuring easier trade and liquidity. Diamonds can only be exchanged for others with identical characteristics, making fungibility limited and liquidity harder.

• Choose gold if you want liquidity, a regulated investment format, an inflation hedge, or a place to park savings for the short-to-medium term.
• Consider diamonds if you're a genuine collector with a 10+ year horizon, you're buying certified natural stones rather than lab-grown ones, and you've accepted upfront that selling won't be quick or easy.
• Consider both if you want exposure to physical assets beyond paper investments; just treat the diamond purchase as a lifestyle or heirloom decision, not a core part of your investment plan.

Choosing between gold and diamonds for investment depends on your financial goals and risk appetite. While diamonds are often purchased for their beauty and occasional resale value, gold stands out as a more stable and reliable investment asset due to its liquidity, fungibility, and store of value.

• Assuming that jewellery is automatically a good investment can be misleading. Making charges and GST often mean you'd need a sizeable price rise in gold just to break even on resale.
• Buying diamonds without certification can make it difficult to prove their quality or authenticity when it's time to sell.
• Forgetting the 24-month holding period rule can lead to being surprised by the slab-rate tax instead of the lower LTCG rate.
• Assuming SGBs are still available to buy fresh and treating an existing SGB the same as a new one can lead to tax surprises after April 2026.
• Confusing a lab-grown diamond's sticker price with its resale value; the two can differ by 60% or more.
