The Government of Greenland’s Diamond exploration data package compiles over 50 years of diamond exploration data. In addition to samples derived from Greenland’s established areas of diamondiferous rocks in central West Greenland, a wide coverage of regional exploration data extending throughout the country is included.The Diamond exploration data package is the first of its kind to collate diamond exploration data country-wide in a publicly accessible fashion. It incorporates the locations of 25 000 diamond exploration samples. Associated with these samples are over 109,000 good-quality chemical analyses of mineral separate grains integrated into a standardised framework. In total, 100 discrete, named in-situ bodies, which in principle have diamond potential (kimberlites, lamproites, ultramafic lamprophyres, and carbonatites) have also been compiled in the diamond exploration data package. These occur among over 3000 compiled in situ occurrences of dykes, pipes, sills and blows.Size: 8.7 GB.

The market continues to evolve, with dynamic interplays between various sectors shaping its landscape. Diamond engagement rings remain a significant application, with GIA certification playing a crucial role in ensuring transparency and trust. Simultaneously, diamond auctions provide a platform for buying and selling polished and rough diamonds, influencing market prices. The 4Cs of diamonds - carat weight, color, clarity, and cut - remain the benchmark for evaluating diamond quality. However, the advent of technology has led to advancements such as irradiation treatment, polishing wheels, and blockchain technology, enhancing diamond certification and traceability. Irradiation treatment alters the diamond's color, while polishing wheels refine its shape.

Blockchain technology offers enhanced transparency and security, ensuring ethical sourcing and traceability. Retail markups vary, with luxury goods commanding premium prices. Meanwhile, the rough diamond sector undergoes continuous transformation, with mining, processing, and value assessment shaping its market dynamics. Rough diamonds are cut and polished to create stunning jewelry pieces, such as earrings, pendants, and bracelets. Investment-grade diamonds attract investors, with conflict-free diamonds gaining popularity due to ethical considerations. Synthetic diamonds, including lab-grown and cultured diamonds, challenge the traditional market, offering cost-effective alternatives. Diamond Mining equipment and processing technologies continue to advance, enabling efficient extraction and refinement. The market's continuous evolution reflects the interplay between technology, consumer preferences, and industry trends.
