This is a bottle that more for collection. This bottle is from Mont Blanc and I have no idea when it was released and don’t know why it’s so hard to find. It’s blue but I have no idea why named Diamond.
It’s blue, slightly darker blue. Similar to Iroshizuku Shin-kai and lighter version of Sailor Yama-dori. About standard long long drying time for blue inks, pretty saturated with some shading. Wet ink flow and didn’t bleed through iPaper UCCU or PaperOne 70gm. No water resistant as usual.
CP value: 60/100, just for collection sake….
