India's diamond market booms as Gen Z and women drive everyday luxury

Across India, younger shoppers and financially independent women are buying diamonds for everyday wear rather than special occasions, propelling the country to become the world’s second‑largest diamond jewellery market and creating a $12 billion industry [1].

Key takeaways

• Gen Z (ages 18‑28) now accounts for 51% of India’s diamond jewellery market value [1].
• More than half of newly purchased natural diamonds are worn daily, up from a minority in 2014 [1].
• Self‑purchasing women are a major growth segment, buying diamonds to mark personal milestones [1].
• India’s consuming class is limited to about 130‑140 million people, deepening wealth gaps and driving premiumisation [2].
• The luxury market’s expansion is supported by a $12 billion tax rebate and a strong rural harvest, though broader middle‑class spending remains constrained [2].

Gen Z and women reshape diamond buying habits

A De Beers India study shows that Indian Gen Z consumers now contribute more than half of the diamond jewellery market’s value, with an average spend of nearly Rs 1.98 lakh per piece [1]. This cohort prefers “wearable luxury,” opting for diamond studs, pendants or rings that can be integrated into daily wardrobes rather than saved for weddings. Women buyers are similarly redefining the market: many are purchasing diamonds for themselves to celebrate career achievements, birthdays or personal milestones, reflecting growing financial independence and a shift away from the traditional gifting model [1].

The shift is also evident in product usage. In 2014, over 50% of diamond purchases were reserved for special occasions; today, more than half of new natural‑diamond pieces are worn regularly, indicating a move from “locker luxury” to everyday adornment [1]. Lighter designs and modern styles are catering to this demand, aligning with broader lifestyle trends that value self‑expression and experience over ceremonial display.

Premiumisation amid a constrained consumer base

While the diamond sector thrives, broader Indian consumer dynamics reveal a stark contrast. A report by venture‑capital firm Blume Ventures estimates that only about 130‑140 million Indians belong to the true consuming class, comparable in size to Mexico’s entire population [2]. The remainder of the population is either “emerging” or lacks discretionary spending power, limiting mass‑market growth. This has accelerated “premiumisation,” where brands focus on high‑end products for affluent shoppers, evident in rising sales of ultra‑luxury housing, premium smartphones and high‑ticket concert events [2].

The report notes that a $12 billion tax giveaway in the recent budget, along with a record agricultural harvest, may modestly boost consumption, but structural challenges—stagnant middle‑class incomes and shrinking savings—remain significant headwinds [2].

Why it matters

India’s diamond boom illustrates how niche luxury segments can expand even when the broader middle class is under pressure. The rise of Gen Z and self‑buying women signals a durable shift toward personal luxury, supporting a market projected at roughly Rs 497 billion and expected to keep growing as higher‑income households expand [1]. However, the sector’s reliance on a relatively small affluent consumer base underscores the importance of broader economic reforms that address income inequality and job displacement, especially as automation reshapes the services sector [2]. Continued premiumisation may sustain high‑value markets, but without wider purchasing power, growth could remain confined to affluent urban pockets.
