Just landed - the GET-Diamonds December update. Baby Boomers are ageing, and with them, the most powerful luxury-buying generation we’ve ever seen. The Inside Edge reveals global trends and an insight into the natural diamond trade.
GET-Diamonds Market Report — December 2025 Edition
Baby Boomers (1946–1964) are ageing — and with them, the most powerful luxury-buying generation we’ve ever seen. What they leave behind is a potential goldmine: millions of dollars’ worth of unworn, inherited jewellery now passing to children and grandchildren.Dealers in the US are already reporting increased trading in second hand goods, both cash purchases and trade-ins. A NY-based jewelry restoration business reports that there has also been a big lift in restoration requests from those wanting to re-sell.
The Opportunity:Retailers and diamantaires who embrace trade-ins have the opportunity to transform “grandma’s old jewels” into purchasing power — attracting young customers who otherwise couldn’t afford to buy new... Read the full story
Wholesale Up / Auctions Up
October average wholesale asking prices across all stones in all regions were up very slightly by about 2%. In a surprise trend auction sale results for diamonds in New York, Paris, London, Geneva & Hong Kong were up around 10%.
The GET-Diamonds Auction Price Estimator and the GET Spot Market Index (DSX) are based on 20,000 real-time public auction results for natural diamonds and diamond jewellery captured from ten of the world’s top auction houses and are available for free on the GET-Diamonds platform.
The holiday season kicked off with natural diamonds taking center stage in New York as Saks Inc. partnered with the Government of Botswana and De Beers for the unveiling of its window displays and light show at its Fifth Avenue store.
Record Season
US holiday retail sales are expected to exceed $1 trillion for the first time after the National Retail Federation (NRF) projected growth of 3.7% to 4.2% during the November-December period. Online sales grew 8% in the first three weeks, according to Adobe.
Trade Levels Slide
Belgium’s rough diamond imports fell 19% year on year to $255.4 million in October, while polished exports inched up 1% to $524.9 million, Antwerp World Diamond Centre (AWDC) data showed. India’s rough imports plunged 45% to $385 million amid the US’s 50% tariffs on Indian goods, and polished exports dropped 27% to $1.03 billion, according to the Gem and Jewellery Export Promotion Council (GJEPC).
India's Growth Plan
The GJEPC presented Prime Minister Narendra Modi with a roadmap to boost India’s gem and jewelry sector to $100 billion in exports and $500 billion in domestic sales by 2047. Proposed reforms include concessional export credit for SMEs and a National Gem & Jewellery Park Policy to enhance global competitiveness.
Healthy Collaboration
Botswana’s minerals and energy minister Joy Bogolo Kenewendo visited the AWDC to thank 18 Belgian diamond companies for humanitarian aid. Antwerp’s diamond community mobilised after Botswana’s medical emergency, helping restore access to essential care for over 35,000 people for a year.
Easing Compliance
The AWDC introduced a digital customer-screening tool that automates anti-money laundering (AML) and know-your-customer (KYC) checks for Antwerp’s 1,470 diamantaires. The EUR 250,000 ($288,000) platform is designed to simplify compliance requirements for members.
Leadership Changes
Key industry bodies announced new leaders ahead of 2026. The Responsible Jewellery Council appointed Purvi Shah, formerly head of De Beers’ ethical-sourcing strategy, as executive director effective February 7. The Natural Diamond Council named Amber Pepper, managing director at Mytheresa and former CMO, as CEO starting February 1, replacing David Kellie. Jewelers of America elected Matthew Rosenheim, president of Tiny Jewel Box, as its new board chair.
Minors Sqeezed
Diamond miners remained under pressure during the third quarter, with revenue slumping at Mountain Province Diamonds (-58%), Burgundy Diamond Mines (-43%), Gem Diamonds (-40%), and Alrosa (-6%). Lucara Diamond Corp. was the exception, posting a 16% increase on strong demand for specials over 10.8 carats.
Tariff Deal Close
The US and Switzerland are nearing a trade agreement that would cut tariffs on Swiss watch imports from 39% to 15%. A US-India deal remains the industry’s top priority, given India’s dominant role in global diamond manufacturing, Jewelers of America CEO Dave Bonaparte said in a webinar.
Lab-Grown Fraud
Gemological Science International (GSI) detected undisclosed lab-grown stones mixed with natural brown diamonds in jewelry, underscoring the need for stronger screening and disclosure as the trade is increasing its marketing of brown diamonds.
Origin to Retail
De Beers launched its Origin brand to 19 retailers in the US and Canada, enabling them to share the story of each natural diamond sourced by De Beers through the Tracr traceability platform.
Gems of Geneva
The Geneva auctions featured notable diamonds, though not all found buyers. The Mellon Blue, a 9.51-carat fancy vivid blue, VVS1 pear shape, led Christie’s Magnificent Jewels sale at $25.6 million, contributing to a $75.6 million total. Sotheby’s achieved CHF 41.3 million ($51.3 million), topped by a 4.50-carat fancy vivid blue, IF diamond at CHF 4.8 million ($6.1 million). The Glowing Rose diamond, expected to fetch about $20 million, was withdrawn.
Florentine Found
The Florentine Diamond, missing for over a century, has reportedly been found in a Canadian vault, The New York Times revealed. The 137.27-carat citron-yellow gem vanished after World War I, when the Habsburgs sent their jewels to Switzerland for safekeeping. Long presumed lost, it reappeared when family members invited the paper to view their private collection.
Argyle Masterpieces
Rio Tinto’s third and final Beyond Rare Tender, Into the Light, attracted strong global demand from jewelers and collectors. The 52-lot, 45.44-carat collection included six “Masterpieces,” featuring some of the last pink, red, and violet diamonds from Argyle’s legacy stock after the mine’s 2020 closure
Reform Failure
The Kimberley Process failed to expand the definition of conflict diamonds, the WDC reported. A small group of participants blocked reform for political reasons, weakening efforts to strengthen the system, WDC president Feriel Zerouki said at the KP Plenary in Dubai.
Personnel Shifts
Stuller, Inc. promoted Danny Clark to CEO effective January 1, 2026, succeeding founder Matt Stuller, who becomes executive chairman of the jewelry wholesaler. Belit Myers will assume the role of president while continuing as COO. De Beers named Kevin Smith chief operating officer, replacing the retiring Burger Greef. Smith’s current role as executive vice president of corporate affairs and strategy will pass to Eirik Wærness, the group’s chief economist. The International Gemological Institute (IGI) appointed Jeff Bennett president of North America operations. Bennett previously spent over 20 years at Tiffany & Co., most recently as vice president of business development and strategic partnerships.
Gold Surges, Diamonds Stall: A look at China’s Shifting Jewellery Landscape
Amid the challenges facing the diamond market in China, jewelry retail appears to have stabilised. Chow Tai Fook’s revenue slipped just 1% in the fiscal half year ending September 30, with same-store sales rising in both Mainland China and Hong Kong-Macau. Luk Fook Holdings, another leading regional jeweler, reported a 26% jump in revenue and a 44% surge in profit during the same period.
Still, most of that growth came from the fixed-price gold jewelry segment. Luk Fook’s diamond sales, by contrast, continued to fall in the low double digits. And consumer caution remains tied to China’s... Read the full story
