The Bohr Radius of Stars | Rose Quartz, Labradorite & Ruby Bracelet

a0 = 4 pi epsilon0 h-bar squared over m e squared. How do you measure the distance between two stars gazing at each other across an endless sky? How do you reckon when two grains of sand in the vast ocean will finally meet? The Bohr radius, from the atomic model physicists proposed in 1913, is the smallest orbit an electron can travel, and it is known as the closest distance in the universe. The galaxy above, the deep sea below. I would fall like a meteor into your Bohr radius.

About the crystals. Every MenWen piece is built around natural stones, chosen for their color and character and set in brass by hand in Taiwan. We treat crystals less as talismans and more as material for wearable art, so each bracelet is a small design object you can carry with you.

Materials. Rose Quartz, Lavender Amethyst, Labradorite, Ruby, Synthetic Quartz. Set in brass.

Sizing. Bead sizes run roughly 3mm to 10mm, and may vary slightly between batches. Choose the wrist measurement closest to your own and we adjust the length so the bracelet sits comfortably and can still turn on the wrist. If your measurement falls between sizes, for example 15.5cm, pick 15cm for a closer fit or 16cm for a looser one.

Shipping. Orders usually ship 1 to 3 days after purchase, excluding national holidays. During promotions, dispatch may take a little longer.
