-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.

Size & Fit

Size & Fit

The clean, elegant luster of platinum enhances the sapphire’s vivid color, while the slim band feels light on the finger and gives the hand a sleek appearance.
Wear it as a refined accent with a shirt or jacket, or add a subtle touch of brilliance to casual looks such as knits and cut-and-sew tops. It looks beautiful on its own, layered with platinum or white gold for a cohesive palette, or paired with yellow gold to emphasize the contrast between metals.

Details

Details

This sapphire layers a hint of purple over translucent pink, revealing either a fresh clarity or a calmer purple tone depending on the light. As with all natural stones, variations in color depth and the way light enters the stone make every piece unique.

The setting is carefully balanced to give the stone presence without feeling overpowering. The natural color of the sapphire and the crisp character of platinum come together in a special piece designed to be worn and enjoyed for years.

BAND

BAND Collection

Unlike conventional stone-setting techniques, this series uses januka’s original setting method, in which grooves are carved directly into the stone to secure it with lines and raised sections of gold. With no prongs or other elements covering the stone, its entire form remains visible, allowing the structure itself—rather than added decoration—to become the design.
Each piece is created through the highly specialized craftsmanship of a gemstone carver in Kofu and a dedicated metalworker. Working with precision down to 0.1 mm, the series is defined by a level of handcraft and expertise that only these individual artisans can achieve.

FAQ

Q. The design looks delicate. Is it fragile?

A.The BAND series is designed with minimal visible metal in order to showcase the natural beauty of each stone. Because of this delicate construction, strong impacts or contact with hard surfaces may cause the stone to chip or break. Please note that durability also varies depending on the hardness and characteristics of the natural stone you choose.

Rather than wearing these pieces continuously every day, we recommend treating them as special jewelry to be worn when going out and handling them with care. With normal wear while out and about, they can be enjoyed comfortably without concern.

Q. What should I do if my jewelry becomes damaged?

A.Please contact us through our official LINE account or the contact form on our website. Once we have assessed the condition of the piece, we will provide you with a repair estimate.

If the stone has broken, we may be able to source another stone with a similar character and remake the piece. However, as every natural stone used in the BAND series is one of a kind, we cannot recreate a piece with exactly the same color, shape, or appearance. We appreciate your understanding.

Q. Can I change the ring size or necklace chain length after purchase?

A.Yes. Please contact us through our official LINE account or the contact form on our website.

Ring resizing and necklace chain length adjustments are available after purchase. The cost will vary depending on the type and extent of the adjustment, and we will provide an estimate once we have confirmed the details of your request.

Q. Will I receive the exact stone shown in the product photos?

A.Yes. You will receive the exact piece shown in the photographs.

Every piece in januka’s BAND series is one of a kind, and each item shown in our online store is individually photographed. The photographs therefore show the actual piece you will receive.

We invite you to take your time exploring the unique shape, color, and individual character of each natural stone and choose the piece that speaks to you.

Q. How should I care for and store my jewelry after wearing it?

A.After wearing your jewelry, gently wipe away any perspiration or oils with a soft cloth or jewelry cloth before storing it.

Because the BAND series exposes a larger surface area of the stone, we recommend storing each piece separately in its own case or pouch to prevent it from coming into contact with other jewelry and becoming scratched.

Please also avoid direct contact with water, cosmetics, perfume, and other substances that may affect the stone.

Q. Can I purchase from outside Japan?

A.Yes. We offer international shipping via DHL.

International orders are subject to a shipping fee of ¥7,000 in addition to the product price. Any customs duties, import taxes, or other fees imposed by the destination country are the responsibility of the customer.

If you have any questions or concerns about placing an international order, please feel free to contact us by email. We will be happy to assist you.

Q. Can I see and try on the pieces in person before purchasing?

A.Yes. You can view and try on pieces at our flagship store in Omotesando, Tokyo.

The store may also have one-of-a-kind loose stones and finished pieces that are not listed in our online store. As our in-store selection changes over time, we recommend contacting us in advance if you are looking for a particular type of stone.
