The varying viewing conditions between graders and polishers may lead to inconsistencies in the evaluation of the polish grade, frequently sparking vivid discussions between graders and polishers. With the Avalon +, a discussion on the polish grade is no longer an issue as all is objectively measured.
Smoothness can be observed by the polisher during the polishing process and without having to remove the stone from the tang, which allows him to intervene immediately when necessary.
To minimise the polisher's subjectivity when assessing a diamond's smoothness, Avalon + allows facet's smoothness to be objectively measured and colour graded according to the HRD Antwerp standards for polish grade.
Avalon + is also equipped to perform facet measurements. Unlike other measuring tools, the Avalon + uses a plane through the girdle as reference for its measurements. This implies that the girdle has to be perfectly round and parallel to the table.
