The diamond industry is navigating its most volatile period in decades as geopolitical tensions, punitive tariffs, and shifting consumer behaviors collide. With the U.S. imposing 10% tariffs on Indian diamonds, 125% duties on Chinese jewelry, and delayed tariff hikes sparking inventory gambles, stakeholders face unprecedented uncertainty.

US Tariffs: Inventory Windfalls and Looming Shortages

The Biden administration’s 90-day postponement of a 26% tariff hike on Indian diamonds (initially set for April 9) triggered a frenzied inventory rush. Indian manufacturers shipped $2B+ of goods to U.S. subsidiaries, creating a temporary tariff-free stockpile. However, the U.S. International Trade Commission warns of Q3 shortages as replenishment costs spike post-deadline.

Signet’s Price Freeze: The jewelry giant locked in prices for confirmed orders, but MIT Sloan School of Management research shows rigid pricing during inflation erodes demand by 15-20%.

GIA’s Lab Relocation: By halting U.S.-bound shipments and expanding Hong Kong/Dubai services, the Gemological Institute of America (GIA) reshapes certification flows. Expect 2-3 week delays for non-U.S. goods.

Deferring Cullinan’s sale reflects miner anxiety. The World Diamond Council forecasts 5-10% Q2 price corrections for rough diamonds.

Stat: U.S. polished inventories are 30% tariff-free, per the National Bureau of Economic Research (NBER), but restocking post-deadline could raise consumer prices by 12-18%.

Fancy Diamonds Defy Chaos:

While rounds stagnate, fancy shapes thrive, driven by celebrity influence and social media trends:

Ovals Dominate: 2.50–2.99 ct. D-I/VS-SI ovals command 5-10% premiums over pears. The American Gem Society (AGS) links this to Blake Lively’s pink oval engagement ring and TikTok’s #OvalObsession.

Emeralds & Radiants Surge: Elongated cuts in 2+ ct. sizes see 15-20% price hikes, fueled by the “quiet luxury” aesthetic (Fashion Institute of Technology (FIT)).

Marquise Mystique: Scarcity of well-cut stones (L/W ratio >1.85) lifts premiums by 12%, per RapNet data.

Warning: Poorly cut fancies (e.g., shallow radiants) are 40% discounted, warns the International Gem Society (IGS).

Conclusion -

Historic tariff shifts have plunged the diamond market into uncertainty, freezing trade and forcing industry adaptation.
