How to Measure Your Correct Ring Size

Thank you for choosing YophieMade for your ring purchase. To ensure that you find the perfect fit, please follow the instructions below on how to measure your ring size.

  1. Choose a Piece of String: Use a piece of string instead of paper or tape for a more accurate measurement.
  2. Wrap the String Around Your Finger: Gently wrap the string around the finger you wish to measure. Ensure it is neither too tight nor too loose.
  3. Mark the String: Mark the point where the ends of the string meet with a pen or marker.
  4. Measure the String: Lay the string flat and measure the length from the starting point to the mark with a ruler. Note the measurement in millimeters or inches.
  5. Determine Your Ring Size: Refer to the ring size chart below to convert the measurement to your corresponding ring size.

A personalized astronomical sphere ring that unfolds from five bands into a small celestial sphere. Add two birthstones to make the piece personal: two people, two children, two memories, or a meaningful pair of months.

When closed, it wears as a ring. When opened, it becomes a sculptural astronomical sphere inspired by antique armillary and celestial rings. You can also choose the necklace option and wear it as a pendant, giving one piece two ways to be carried.

Details
- Style: foldable astronomical sphere ring
- Personalization: two birthstones
- Material options: brass or sterling silver
- Ring width: approximately 4-4.5 mm when closed
- Thickness: approximately 2.5 mm
- Wear options: ring only or with necklace
- Necklace choice: Without Necklace = ring only; With Necklace = ring plus chain
- Handmade to order by YophieMade

The design is inspired by a 16th-century astronomical ring preserved by the Swedish History Museum. The structure is adjusted for everyday wear, with a comfortable thickness and a satisfying opening motion.

This ring is a meaningful choice for a birthstone gift, promise gift, anniversary gift, celestial jewelry lover, fidget ring, or keepsake for someone who loves objects with movement and story.

Open and close the ring gently, and avoid forcing the bands. Remove it before swimming, bathing, heavy exercise, or applying lotions and perfumes. Store it dry and clean gently with a soft cloth.
