These moonstone earrings look as if they’ve captured actual particles of light.
A subtle shimmer floats within the translucent stone. That fleeting flicker of light glows softly, as if whispering in your ear. The pale glow that streaks across the stone’s surface like a ribbon changes its expression depending on the angle and lighting, creating a subtle yet striking presence that catches the eye in unexpected moments.
This moonstone features a unique cut that is almost a soft triangle, leaving a fresh impression on the viewer. The setting follows the “Band Series” design. A single gold line running through the center of the stone tones down the sweetness, giving the overall piece a crisp, refined look.
Wear one in each ear for an asymmetrical look, or pair them together to incorporate into a monochromatic, transparent-toned outfit. These earrings add a core of style to your look without being overly flashy. Because they are set at an angle relative to the piercing hole, their three-dimensional form stands out even when viewed from the front.
Pair them with off-white or gray tops to highlight the earrings’ translucence and create a sophisticated look. Even when mixed with different materials like denim or leather, the moonstone’s soft glow maintains a perfect balance.
A statement piece that blends seamlessly with your skin. This neutral, elegant pair delivers both.

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.

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.
