    A terrific presentation, thanks for sharing this! $60,000 a carat for Paraiba was a surprise.

    I think that Kashmir sapphires with their top color are worth more than both the Burmese ruby & Paraiba tourmaline, auction results are often above $150,000 per carat

    I own an emerald cut violet tourmaline, 1 or 2 shades darker than the oval violet positioned between the two green ovals in the lower image of the slide that kicks in at the 19:50ish point. I would love to heat with the hopes of it turning that caribbean blue but the minor air bubbles and inclusions have me fearful of it exploding into shards. It's also strangely attracted to my high power magnet when I do a drift test floating it on polystyrene on water. I wonder if it has "paraiba" color potential. Are paraibas magnetic? Does anyone know? Thanks.

    What about Chrome Tourmaline that turns pink/red when under UV light? Is the price of those per ct the same as just the Chrome one listed?
