From deep, mysterious royal blue to fancy pink. We offer the rich colors unique to natural sapphires.
KENSINGTON DIAMONDS Co., Ltd. (Headquarters: Minato-ku, Tokyo; Representative: Thompson Hanna) has launched a new jewelry collection using natural sapphires, in addition to its natural diamond jewelry.
Since its founding, the company has adhered to the philosophy of “maximizing the inherent beauty of natural diamonds,” carefully assessing the quality of each stone to deliver jewelry that can be cherished for years.
This new collection extends that philosophy to natural sapphires.
From the deep, captivating royal blue to the gentle, delicate pink, and the unique colors of natural stones—no two are alike. Sapphire jewelry that highlights each stone’s individuality adds a new dimension to the diamond collection.
All jewelry is semi-custom and made to order. Customers can choose from platinum or gold settings, tailored to their lifestyle and preferences. Additionally, GIA certificates are provided for sapphires, ensuring a commitment to quality.
Sapphires, with a hardness second only to diamonds, are gemstones meant to be passed down through generations.

Natural Pink Sapphire 1.19ct K18YG ¥451,000 (including tax, after setting)
Sapphires boast high hardness, second only to diamonds, combining beauty and durability. Due to these excellent properties, they have long been cherished worldwide for engagement rings and anniversary jewelry.
Depending on rarity factors such as color, clarity, and origin, sapphires can sometimes trade at values exceeding natural diamonds, making them highly regarded gemstones globally.
KENSINGTON DIAMONDS selects natural sapphires with the same quality standards as its diamond jewelry, offering a diverse collection of designs.
We propose the beauty that only natural sapphires can express: a sophisticated contrast with colorless diamonds, deep blue enhanced by yellow gold, and an elegant combination with platinum.
Not just for engagement rings, but as lifelong jewelry to adorn daily life.

KENSINGTON DIAMONDS believes jewelry should accompany life not only at milestones but also in everyday moments.
Sapphire jewelry can be chosen not only for engagement rings or anniversary gifts but also as a reward for oneself or a talisman to wear.
Layering with existing diamond jewelry creates new expressions in your outfit.
At our showroom, you can try on actual samples while we propose a piece that resonates with your personal story.
KENSINGTON DIAMONDS is a diamond-specialist jewelry brand handling the highest quality natural diamonds.
Designed in London and meticulously crafted one by one by skilled Japanese artisans, each piece is made to bring out the diamond’s natural brilliance.
We pursue designs that highlight each stone’s individuality and ensure comfortable wear even for extended periods. Our range includes bridal jewelry such as engagement rings and eternity rings, as well as fashion jewelry like necklaces, earrings, and bracelets to adorn daily life.
In summer 2026, we add a new natural sapphire collection, offering colored stone jewelry selected with the discerning eye of a diamond specialist brand.
