ダイヤモンド市場規模、シェア、成長分析：製品別、用途別、カット別、カラー別、カラット別、流通別、地域別 - 産業予測 2025年～2032年

ダイヤモンド市場規模は 2023年に1,001億米ドルで、2024年の1,046億米ドルから2032年には1,487億6,000万米ドルに成長し、予測期間（2025-2032年）のCAGRは4.5%で推移する見通しです。

卓越した硬度と熱伝導性で知られるダイヤモンドは、高級な宝石として、また切削工具や研削工具に不可欠な材料として、二重の役割を果たしています。極度の圧力と温度下で形成されるダイヤモンドのバリューチェーンは、ダイヤモンド原石の探査や選別といった上流工程、カッティングや研磨といった中流工程、宝飾品のデザインや制作といった下流工程を含みます。アジア太平洋の新興経済国、特にインドと中国が、ダイヤモンドジュエリーの需要を急増させており、中国は歴史的に最大の採掘ダイヤモンド消費国となっています。技術の進歩が進むにつれて、中国は合成ダイヤモンドの主要生産国として台頭し、2024年から2031年の間に市場情勢を大きく変える可能性があります。
