THE. PIECE.
蒼心 | Sōshin - Blue Heart
Stillness. Truth. Strength.
Built from quiet power and calm awareness.
Rock Crystal holds steady — clear, calm, and unwavering. Sodalite sharpens truth and deepens vision.
Together, they bring a strong inner stillness. Finished with the silver seal — sharp, balanced, and focused.
Made for the man who sees through the fog.
YOUR BEADS. YOUR JOURNEY.
YOUR. FIT.
Your Fit
Each Rengetsu piece is sized by its inner circumference - designed to match the wrist it's made to fit.
How to Measure
Wrap a soft tape measure - or a string you can mark - around the smallest part of your wrist.
Measure tightly. The measured number is your Close Fit; add 0,5 cm (or 0.2") if you prefer a Comfort Fit.
Between two sizes? Go up.
True strength leaves room to move.
