KAJITA, a colored-stone jewelry brand based in Omotesando, Tokyo, and operated by Kajita Co., Ltd. (株式会社梶田), is adding three new pieces to its "KAJITA Diamond" collection: the "Diamond Bangle," the "Diamond Tennis Bracelet S" and the "Gradation Eternity Ring." They go on sale at "KAJITA JEWELLERY Showcase - Diamond and Chain -," which opens on Thursday, October 22, 2026.
KAJITA has long made jewelry that brings out the individuality of each gemstone, centered on richly colored stones. In recent years, its diamond jewelry, which reflects an eye for gemstones built up over many years and a commitment to quality and design, has also drawn attention from many customers.
To bring out the timeless beauty of diamonds, KAJITA pays close attention to every detail, from the quality of the diamonds to the setting of the stones, the overall proportions, and the beauty and comfort of the piece when worn.
The three new pieces are designed so that the sparkle of diamonds can be added naturally to everyday style. Each has a modern, timeless design that looks refined on its own and can also be layered with jewelry you already own.
Diamond Bangle (ダイヤモンド バングル)
Developed over a long period in response to many requests from customers, this bangle features carefully selected, high-quality diamonds set with delicacy to bring out the natural brilliance of the stones. Because the back is not hollowed out, the side that touches the skin feels smooth, and the bangle has the comfortable weight typical of fine jewelry.
It comes in two types: a 1ct type with a subtle sparkle that suits stacking, and a 2ct type that shows off the glamorous presence of the diamonds. Three materials are available: platinum, yellow gold and pink gold. With a minimal form that holds the elegance of diamonds, it gives daily style a more refined look.
PT950 Diamond: 1ct ¥630,000 / 2ct ¥860,000
K18YG Diamond: 1ct ¥690,000 / 2ct ¥960,000
K18PG Diamond: 1ct ¥690,000 / 2ct ¥960,000
The bangle is offered in two sizes, S and M. The M size costs ¥40,000 more than the prices above.
Diamond Tennis Bracelet S (ダイヤモンド テニスブレスレット S)
A new design joins the Diamond Tennis Bracelet, a KAJITA staple that has been well received. Fine lines of metal are placed between the diamonds, giving the bracelet a light, rhythmic look. It treasures the beauty of each individual diamond while blending naturally into everyday outfits.
PT850 Diamond: ¥352,000
K18YG Diamond: ¥388,000
Prices vary with the length ordered.
Gradation Eternity Ring (グラデーションエタニティリング)
This eternity ring varies the size of the diamonds to create a flowing sparkle. With attention to the quality of the diamonds and the beauty of the setting, it adorns the fingers with glamour while keeping a refined impression. It is also recommended as a pinky ring.
