Debt-free jewellery exporter with 90% LGD mix and ₹504 crore cash chest becomes the sector’s most compelling trade deal play

By S. Jha

Mumbai, April 16, 2026 — Shares of Goldiam International Ltd (NSE: GOLDIAM) surged approximately 14% on Wednesday, extending a remarkable multi-week run that has established the Mumbai-based lab-grown diamond jewellery exporter as one of the standout momentum stories in India’s mid-cap universe. The stock, which trades near the ₹380–390 range, has recovered sharply from its 52-week low of ₹251.35 — driven by a near-perfect convergence of geopolitical tailwinds, sector-specific catalysts, and company-specific fundamentals.

The Big Macro Trigger: India-US Trade Deal

The story of Goldiam’s rerating begins with the landmark India-US trade framework announced in early February 2026. Goldiam International hit the 20% upper circuit at ₹357.70 on the NSE on February 3, as shares of Indian gold jewellery makers and exporters zoomed up to 20% after the US reduced reciprocal tariffs on India from 25% to 18%. In the week following the trade deal announcement, the stock zoomed 43% — supported by a three-fold jump in average trading volumes.

But Goldiam’s advantage goes deeper than a tariff cut. The recent US trade deal, combined with Goldiam’s ‘Made in USA’ strategy — casting in the US, finishing in India — results in effectively zero tariff on their jewellery exports to the US, creating a significant competitive advantage over peers. According to analysts at MNCL, the company delivered its best-ever quarterly performance in Q3 FY26, highlighting the strength of its B2B export franchise, advantage following adoption of the US-based casting strategy, and scaling of the B2C franchise. MNCL reiterated a ‘BUY’ with a revised target price of ₹515.

Q3 FY26: Best Quarter in Company History

The financial underpinning of this rally is rock-solid. Goldiam’s consolidated net profit stood at ₹68.4 crore in Q3 FY26, up 37% year-on-year, while revenue grew 18% to ₹339.7 crore. EBITDA rose 28.2% with margins expanding to 26.7% from 24.6% a year ago. PAT margin improved to 20.1% from 17.3%.

For the nine months ended December 2025, revenue jumped 30% year-on-year and PAT soared 42%, with EBITDA margins improving by 210 basis points to 26.7%. Crucially, the company maintained its debt-free status with cash and investments of ₹5,041 million as of December 2025 — a rare balance sheet fortress in a capital-intensive sector.

Executive Chairman Rashesh Bhansali said that the B2B jewellery export business “continues to deliver consistent growth and margins, supported by higher wallet share from existing customers, addition of new large-format US retailers, and expansion into Europe, the Middle East and Australia,” according to Business Standard.

Lab-Grown Diamonds: The Structural Shift

Lab-grown diamond jewellery exports contributed 90.5% to overall export sales in Q3 FY26, up sharply from 80% in Q3 FY25, while online revenue contribution rose to 31.6% of total revenue. This is not a passing trend — it is a deliberate, multi-year strategic transformation that has repositioned Goldiam as a pure-play LGD exporter at a time when US consumer appetite for lab-grown diamonds continues to grow.

Indian companies exported gems and jewellery products worth $9.15 billion in 2024, making it the second biggest export category to the US after electrical and electronic equipment. Goldiam, with the highest export intensity in the listed space, stands to capture the maximum upside from every percentage point improvement in the trade relationship. Analysts at Finowings estimate Goldiam’s EPS could improve by 15-20% for FY27 as a direct result of the India-US trade deal.

ORIGEM: The B2C Wildcard

Beyond exports, Goldiam is quietly building a domestic retail empire. The company opened its 24th ORIGEM store in Faridabad on April 9, 2026, following store openings in Hyderabad and Bengaluru on April 6. ORIGEM is positioned as a right-priced lab-grown diamond jewellery brand, supported by Goldiam’s integrated sourcing and manufacturing advantages, offering IGI-certified jewellery with lifetime buyback and exchange — differentiating it from peers. Management targets approximately 40 stores by the first half of FY27.

Technicals and Valuation

Technically, the stock has broken out of a prolonged consolidation zone on above-average volumes — a bullish signal across all timeframes. The 52-week high stands at ₹444 against a low of ₹251.35, and the stock trades at a P/E of 27.20x and P/B of 4.27x — reasonable for a company growing PAT at 37–42% with zero debt, ₹500 crore of cash, and a structural tailwind from global lab-grown diamond adoption.

The key risk to watch: any reversal in the India-US trade relationship or a sudden crash in lab-grown diamond prices — both of which have been volatile in recent years.
