Abstract：
The jewelry auction market serves a value-discovery function and is closely associated with mid-to-high-end consumption, making it a useful lens through which to examine trends in such consumption. This study draws on publicly available jewelry auction transaction records published by China Guardian Auctions and Poly Auction from 2011 to 2025 as its data sources. By integrating gemological classification standards with geospatial data processing methods, we developed the dataset through key technical procedures, including the construction of a Chinese jewelry lexicon, jewelry lot identification, and multidimensional data aggregation. The dataset includes: (1) spatiotemporal distribution data summarizing jewelry auction transactions from the two auction houses. The dataset covers the period from 2011 to 2025 and encompasses seven major jewelry auction centers in China: Shenzhen, Macau, Shanghai, Sanya, Xiamen, Hong Kong, and Beijing. It focuses on seven major jewelry categories: white diamonds, colored diamonds, rubies, sapphires, emeralds, jadeite, and pearls. (2) statistical data related to jewelry auction transactions conducted by the two auction houses from 2011 to 2025, including: (a) annual transaction scale in China's jewelry auction market; (b) transaction scale across seven major jewelry auction centers in China; (c) annual transaction volume, transaction value, average transaction price, the structural change indices of transaction volume and transaction value for the seven jewelry categories; (d) transaction volume, transaction value, average transaction price, the location quotients of transaction volume and transaction value for the seven jewelry categories across the seven major jewelry auction centers in China. The dataset is archived in .xlsx and .shp formats, and consists of 9 data files with data size of 123 KB (compressed into one file with 57.2 KB).
