-Points for choosing ring size

The size of a ring varies depending on the design and other factors, even if the number is the same.
If you want to know the size yourselfRefer to the following

【Arm width】

  • thick：Tendency to feel a little pressure due to the large adhesive surface between fingers
    　　→ A slightly larger size is recommended.
  • thin：Tendency to turn easily and feel loose
    　　→ A slightly smaller size is recommended.

【feeling of wearing】

  • Too tight
    → If you feel congestion or pain when you goop your hands
  • Too loose
    → When removing it, the joint, skin, or flesh is not caught and it comes off easily. Or if it comes off when you wave your hand.

【How to measure your own size】

  1. Cut a long strip of paper about the width of the ring.
  2. Wrap the paper around the thickest part, such as the second joint of your finger or the base of your finger.
  3. Mark the areas where the paper overlaps with a pen.
  4. Remove the paper from your fingers and measure the length of the marker.
  5. Find the closest number in the "Finger Circumference" section of the ring size chart above.

#3931
This striking sapphire ring features a transparent light blue and a deep navy blue that blend naturally within a single stone. The appearance changes depending on the angle from which it is viewed, giving it a calm atmosphere with a playful nuance.

The rounded shape brings out the soft light of the stone, and the glossy finish fits gently on the hand. The stone contains minimal zoning and natural inclusions, which further highlight its unique character as a one-of-a-kind piece.  

The design features a gold line running horizontally across the center of the stone, a signature form of the “Band Series.” It preserves the stone's presence while achieving a refined finish. The gold frame is kept to a delicate thickness, creating a sleek appearance when worn on the finger. It adds a subtle touch of elegance to simple outfits.

Band series

Unlike conventional stone clasps, this unique stone clasp is set with gold lines and unevenness by digging a groove in the stone. The stone is not covered by claws, so the entire view of the stone can be seen, and the non-decorative structure is a feature of the design. The series is the result of handiwork that “only a person can do” to the nearest 0.1 millimeter, using advanced processing techniques by a precious stone engraver and a craftsman dedicated to metalworking in Kofu.

Material
  • gem stone (sapphire)
    It is famous as the birthstone for September. It belongs to the corundum mineral species and comes in a variety of colors, from pure blue to greenish blue and purplish blue.
