TASAKI bridal jewellery (engagement and wedding bands)

What distinguishes TASAKI from other brands?

TASAKI's bridal collection is conceived with the finest level of craftsmanship and a meticulous attention to detail. The collection encompasses a wide variety of pieces, from extravagant, design-focussed rings to simpler more everyday pieces. Our rings have been created to emphasise comfort, something that is endorsed by many of our clients. The bridal collection uses Pt950 platinum, a material which has been hardened with a specialist technique to create durable rings that will last for many years to come. Moreover, the diamonds in TASAKI's eternity rings are set perfectly flat and facing the same direction, bringing out the utmost sparkle through optimum light reflection.

What is special about TASAKI diamonds?

TASAKI showcases incomparable brilliance and quality, taking the finest rough stones and, through superior polishing techniques, transforming them into unique and fashionable creations.
TASAKI now achieves a grade of 3EX (Triple Excellent) for 100 percent of the diamonds it cuts. Only these 3EX diamonds are used for TASAKI BRIDAL pieces.

Can products be made to order?

We can create a new piece based on an existing design in your preferred size. For new pieces requested as full custom or semi-custom orders, a quotation will be provided.Please note that production is subject to certain limitations, and requests may not be accommodated depending on the design.

For products without a Diamond Grading Report or Gem Identification Report, please be assured that the TASAKI logo engraved on the product certifies that it was manufactured by TASAKI. Please note that we cannot replace a TASAKI Diamond Grading Report with one issued by an external agency.
