Abstract

Diamonds of the Pioneer pipe, compared with the Arkhangelsk and Karpinsky-1 pipes, formed at higher temperatures, as well as were in such conditions for a longer time (experienced high-temperature annealing). Pionerskaya pipe has slightly lower productivity, but higher quality of diamonds, especially in large size classes, it also has a higher proportion of octahedra and highly transparent crystals that are not subject to accessory etching.
