Compared to diamonds from the Arkhangelskaya and Karpinsky-1 pipes, diamonds from the Pionerskaya pipe formed at higher temperatures and were exposed to such conditions for a longer time (the underwent high-temperature annealing). The Pionerskaya pipe has a slightly lower productivity, but the quality of diamonds is higher, especially in large size classes. In addition, it has a higher proportion of octahedra and highly transparent crystals that were not subjected to accessory etching. [ABSTRACT FROM AUTHOR] |
