A single earring featuring a boulder opal with a blue-gray base and flashes of green and red. Rather than a type that sparkles intensely and dazzlingly, this stone subtly reveals its colors depending on the light and viewing angle. Its slightly irregular, almost triangular shape is also a distinctive feature, resulting in a design that retains the opal’s glamorous appeal while remaining easy to incorporate into casual outfits. This is a one-of-a-kind piece that allows you to enjoy the unique colors and shapes inherent to natural gemstones.
*As this is a one-of-a-kind item, it will be available only while supplies last.

Size & Fit
With a subdued color palette based on blue-gray and a play of color that isn’t too intense, these earrings are easy to incorporate into your everyday style despite being made with colored gemstones. Combined with their irregular shape, they avoid looking too polished, making them easy to pair with casual outfits like jeans and shirts.
Since these are sold individually, we recommend having fun with your look by mixing and matching instead of wearing matching pairs. You can freely experiment by choosing different colors or shapes from our other boulder opal selections, pairing one side with a pearl, or combining it with a simple metal earring. Choosing different earrings for each ear also helps bring out the unique character of each stone.
Details
Boulder opal is a type of opal that is polished while retaining a portion of its host rock, resulting in significant variations in base color, patterns, and play-of-color from stone to stone. This particular specimen features a subdued blue-gray base with fine play-of-color centered on green and red. Rather than displaying vivid colors across the entire surface, it is characterized by a subtle luster where colors appear and fade as light hits different areas.
The shape is not overly symmetrical, allowing the natural contours of the boulder opal to shine through. Since it is difficult to find stones of exactly the same color and shape, we have chosen not to force a pair but have instead selected each stone based on its individual charm and crafted it into a single-earring design.
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.
