When it comes to investment, gold still beats diamonds

Gold demand in India continues to remain strong heading into 2026, reflecting a blend of traditional consumption and evolving investment preferences.

At the same time, the global diamond market is expanding steadily, driven by jewellery demand and export growth. But from an investment perspective, how do gold’s stability and diamonds’ appreciation potential compare in terms of risk and returns?

Gold has long been the go-to asset for Indian investors—valued not just for its beauty but also for the financial security it offers.

For generations, buying gold was not only about wedding jewellery; it was a thoughtful move rooted in culture, tradition, and long-term wealth preservation. However, in a world of evolving investment choices and rising aspirations, a new debate is gaining traction: investing in gold versus diamonds. Which truly stands the test of time?

For most investors, gold outshines diamonds due to its superior liquidity, lower entry barriers, and relatively stronger returns. Diamond investment in India requires specialised knowledge and higher initial capital, with investment-grade stones appreciating at a more modest average of about 8 per cent annually.

Both gold and diamond jewellery attract a 3 per cent GST at the time of purchase. Capital gains taxation also applies when these assets are sold.

Long-term capital gains (LTCG) are taxed at 20 per cent with indexation benefits or 12.5 per cent without indexation if the asset is held for more than 24 months. Short-term capital gains (STCG) are taxed according to the investor’s applicable income tax slab. When comparing the two, gold offers better price transparency and well-established trading markets, while diamonds provide aesthetic appeal, exclusivity, and the possibility of premium pricing for rare stones.

A comparison between physical gold and gemstones also highlights differing risk profiles. Gold prices can fluctuate due to macroeconomic factors such as inflation, currency movements, and geopolitical tensions.

Diamonds, on the other hand, carry risks related to authentication, liquidity, and changing fashion trends. As a result, financial planners often suggest allocating a larger share to gold than diamonds if both are included in a portfolio for diversification.

Although Indians have long adorned themselves with diamond jewellery, viewing these sparkling gemstones as a serious investment option is a relatively recent trend. Both gold and diamonds are precious assets, but their valuation mechanisms differ significantly.

Gold is a commodity with standardised pricing and globally recognised benchmarks. Diamonds, by contrast, are luxury goods whose value depends heavily on the 4Cs—cut, colour, clarity, and carat.

This difference is not merely academic; it directly affects liquidity, pricing transparency, and value appreciation.

One of the biggest advantages of gold investment in India is this standardisation. One gram of 24-carat gold in Mumbai is essentially identical to one gram in Delhi or Chennai. In contrast, every diamond is unique, making the investment landscape far more complex.

Gold clearly wins the liquidity battle. Gold jewellery or coins can typically be converted into cash within hours at thousands of jewellers, banks, or gold buyers across the country. The same cannot be said for diamonds. Gold generally maintains its value upon resale—apart from deductions for making charges—based on weight and purity. However, diamond resale values can vary widely, with sellers often receiving only 20–60 per cent of the original purchase price.

Moreover, finding a buyer may take weeks or even months. A major reason for this difference is familiarity. Gold prices are quoted daily and widely understood. Turn on any financial news channel and the day’s gold rate is readily available. Diamond pricing, however, is far less transparent.

Even with certification, determining the value of a specific diamond requires expertise that most investors do not possess. Additionally, while gold buyers are widely available, diamond buyers with both the expertise and liquidity to purchase stones are relatively rare.

This lack of price transparency often gives dealers an advantage over individual investors when it comes time to sell.

Gold has also delivered strong returns over the past decade. Prices have surged more than 200 per cent during the last 10 years. In comparison, according to the Knight Frank Luxury Investment Index 2024, natural diamonds have generated average annual returns of about 8 per cent over the same period.

Gold prices are influenced by macroeconomic drivers such as geopolitical tensions, inflation concerns, and central bank purchases. Diamonds, however, are influenced more by jewellery demand, luxury spending patterns, and marketing efforts by major industry players.

The tax structure for both gold and diamond jewellery investments includes a 3 per cent GST at the time of purchase. When sold, gains on assets held for over 24 months are treated as long-term capital gains and taxed accordingly.

GST has standardised taxation for both assets across India, eliminating the state-level variations that previously existed. From a capital gains perspective, gold enjoys another advantage. Its standardised pricing makes calculating purchase and sale values relatively straightforward. In contrast, the lack of uniform pricing for diamonds can make tax reporting more complicated.
