Pre-colonial Caribbean jade objects from the National Museum of Denmark Hatt Collection were subjected to a provenance and microwear analysis. Thirty-nine jade celts and bodily ornaments from the US Virgin Islands, i.e., St. Croix, St. Thomas, St. John, and five celts from the West Indies of unknown location, St. Vincent, Cuba and the Dominican Republic were analysed.

A comprehensive in-depth examination of jade adornments from St. Croix, combining typo-technological and microwear analysis, is compared to other lithologies used for pre-colonial ornaments. A portable laser ablation system was used to sample jade celts and bodily ornaments on site in a quasi-non-destructive manner. Low-blank trace element and Sr-Nd isotope ratio data were evaluated with a multiclass regression provenance prediction model.

This study demonstrates that the pan-Caribbean exchange of jade raw materials, pre-forms or finished objects during the Ceramic Age (400 BC to AD 1492) occurred on a more complex scale than previously thought involving jade sources in Guatemala, eastern Cuba and the northern Dominican Republic. In addition, the study of ornaments recovered from St. Croix reveals use of specific lithologies suggesting stronger ties to Indigenous communities on Puerto Rico than other Lesser Antillean Islands.

丹麦国家博物馆哈特收藏的前殖民时期加勒比海玉器经过了出处和微磨损分析。分析了来自美属维尔京群岛（即圣克罗伊岛、圣托马斯、圣约翰）的 39 件玉石和身体装饰品，以及来自西印度群岛、圣文森特、古巴和多米尼加共和国的 5 件玉石。 .

对 St. Croix 的玉器装饰品进行了全面深入的检查，结合了打字技术和微磨损分析，并与用于前殖民装饰品的其他岩性进行了比较。使用便携式激光烧蚀系统以准无损的方式在现场对玉石和身体装饰品进行采样。使用多类回归来源预测模型评估低空白微量元素和 Sr-Nd 同位素比数据。

这项研究表明，在陶瓷时代（公元前 400 年至公元 1492 年）期间，泛加勒比地区的玉石原料、预制件或成品的交换规模比以前认为的涉及危地马拉、古巴东部和多米尼加共和国北部。此外，对从圣克罗伊岛回收的装饰品的研究揭示了特定岩性的使用，表明与其他小安的列斯群岛相比，波多黎各与土著社区的联系更为紧密。
