卖不动了？钻石价格大跌！十年前1.8万元买的钻戒 如今只能卖180元

Core Viewpoint - The diamond industry is facing one of its most severe and prolonged crises in modern history, influenced by declining luxury consumption in major markets and the rising popularity of lab-grown diamonds. The recent imposition of tariffs by the U.S. on India, the largest diamond exporter, has further exacerbated the situation [1]. Group 1: Price Adjustments and Market Dynamics - De Beers, the world's largest diamond producer, has announced a price reduction for rough diamonds, marking a significant move in response to declining market demand [2][3]. - During its first diamond auction of the year, De Beers implemented a unified pricing policy, making it difficult to assess the exact extent of the price cuts, with industry insiders estimating a reduction of 10% to 15% [3]. - The RapNet Diamond Price Index indicates that prices for smaller diamonds, particularly those between 0.3 to 0.5 carats, are expected to drop significantly, with a projected decline of over 20% for 0.5-carat diamonds in 2025 [3][4]. Group 2: Inventory and Sales Performance - De Beers has accumulated over $2 billion in inventory, and the success rate of its diamond auctions has been declining, reflecting weak end-user demand [5]. - The U.S. finished diamond imports are projected to decrease by 48% year-on-year in 2025, indicating a lack of consumer confidence and a shift towards lighter gold jewelry due to high gold prices [5]. Group 3: Impact of Lab-Grown Diamonds - Lab-grown diamonds are increasingly capturing market share, with their sales accounting for over 40% of the global diamond jewelry market by 2025, an increase of more than eight times since 2019 [10][11]. - The retail prices of lab-grown diamonds have plummeted by over 50% from their peak, with the price of a 1-carat lab-grown diamond dropping from 8,000 yuan to 3,500 yuan, significantly undercutting natural diamonds [11][15]. - The Chinese market for lab-grown diamonds is thriving, with a production increase of 144.44% in 2024, making up 63% of global output [13].
