First bridal collection by PRMAL

Ethical diamond jewelry brand PRMAL launched its first bridal collection on March 25, 2022.

Engagement rings are available in 72 different arm and top combinations, and wedding rings are available in 12 different styles. Each ring is available in platinum, yellow gold, or white gold.

The minimalistic designs that maximize the charm of the lab-grown diamonds themselves are expressed with exceptional craftsmanship. We propose reasonable prices that are possible only online, and you can purchase diamonds twice the size of natural diamonds for the same budget.

All jewelry pieces are hand-made by jewelry artisans in Kofu, Japan, and 1% of the purchase price will be donated to environmental conservation organizations through the 1% for the Planet program. We can deliver custom-made rings in as little as 30 days.

Bridal Collection

Bridal is the beginning of a new journey with your lifelong partner. From timeless designs to unique pieces, you can choose bridal jewelry representing the strong bond between you and your future partner.

All engagement rings are accompanied by a diamond certificate of authenticity from the International Gemological Institute (IGI), based in Belgium. The center stone is the subject of the certificate.

Home Try-On

A ring is a symbol of eternity to be shared for a lifetime. We offer a ring sample rental service so that you can try on rings.

By trying on the ring at home, you can try it on to your heart's content to see how it looks on your finger, how comfortable it feels to wear, and how it will look with your other jewelry.

About ring samples

The ring has the same design as the actual ring, with four different ring arms and tops, and you can choose the size and layout of your favorite diamond at home. The sizes are standardized as to size 9 for women and size 15 for men. You can check your ring size with the included ring sizer.

How to try

After ordering your desired sample set online, we will send you a ring sample along with a ring sizer. The loan period is 10 days. A deposit is required at the time of order and will be refunded upon return.
