The Second Diamond

Double Diamond promises elegant convergence, but real growth happens through the fractal madness of self-repetition, accumulation, and crystallisation under pressure.

Whether you’re strolling along the shore or heading to a daily stand-up meeting, this T-shirt brings the coastal calm with you — grounded, reflective, and city-ready.
