Comment: Finest cornflower blue at day, changing to soft violet-purple at night - the classic CC in sapphire. Sought-after cleanest crystal without inclusions. No window, no treatments, no inclusions. Flawless handcut by celebrated local artisan earning a rare 'excellent' without precision cut. It does not get better in classic CC sapphire only bigger. AIGS certified pedigree 'Sri Lanka' and no heat. Always dripping with color, zero black-out, never 'just' blue, never pale, no weakness in mixed light but magic show of blue-violet-purple melange. Even in lowest light, still a glowing purple (see last night image). This gem makes me wish I had paid more attention to quantum physics at school. Luster rolls smoothly from left to right. Full size in perfect-color best-quality untreated CC sapphire for rings over 5 and upto 12, with many setting-options due to shape, deserving a halo of best diamonds for gents or ladies.
