This Ametrine ring from the Band Series features a striking layering of translucent colors. Ametrine, in which shades of purple and pale gold coexist within a single stone, reveals different expressions depending on the angle of the light and the viewer’s perspective, evoking a sense of quiet depth. The gradient where different colors blend naturally is a charm unique to natural gemstones that is difficult to reproduce artificially.
The stone has been meticulously shaped into an elegant form, and the sharpness of its outline accentuates the color boundaries with greater clarity. A single line—a signature feature of the Band Series—is positioned to traverse the center of the stone, creating a finish that is simple yet structurally cohesive as a design element in its own right. Rather than encasing the stone, this structure supports it like a ribbon, naturally highlighting the stone’s transparency and shifting hues.
The ring is crafted from 10K yellow gold. The subdued gold hue harmonizes gently with the ametrine’s purple and gold tones, lending the piece an overall soft impression. The slender band is designed to balance and highlight the central stone, resulting in a comfortable fit that lightly hugs the finger.
Ametrine, whose color shifts depending on the viewing angle, allows you to enjoy subtle changes throughout your daily activities. Rather than making a bold statement, the layers of color spreading within the transparent stone serve as a subtle accent, lending a gentle presence to your hand.
The design of the Band Series, with its minimalist structure, focuses on expressing the stone’s individuality as it is. By avoiding unnecessary embellishments, the design naturally highlights the stone’s color, form, and the way it catches the light.
Since ametrine is a natural stone, the distribution of color, shades of intensity, and the placement of gradients vary from piece to piece. Even with the same cut, each stone possesses its own unique character, and no two are exactly alike. These subtle differences are what shape the jewelry’s individuality.
The Ametrine Ring from the Band Series harmonizes the simplicity of its structure with the stone’s colors. The two hues that unfold within the transparent stone shift quietly on your hand, adding a gentle splash of color to your everyday life.
As this is a one-of-a-kind piece, it will be available only while supplies last.
If you purchase a size other than 11, please allow 1.5 months for resizing.
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.

Details
アメトリンは、アメジストとシトリンがひとつの結晶の中で共存する天然石です。
紫と淡いゴールドが織りなす自然なグラデーションは、光の当たり方や見る角度によってさまざまな表情を見せ、静かな奥行きを感じさせます。
天然石のため、色の入り方や濃淡、グラデーションの位置は一点ごとに異なります。同じカットであっても、それぞれが固有の表情を持ち、同じものは存在しません。
リングにはK10イエローゴールドを使用。落ち着いたゴールドカラーがアメトリンのやわらかな色彩と調和し、肌に自然と馴染みます。bandシリーズならではの枠を持たないセッティングにより、側面や裏側からも石の内部まで眺めることができ、天然石本来の美しさを存分に楽しめます。
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.
