  • I wanted you to wear the engagement ring at the wedding,
    so I kept it unopened until this day.
    From today on, we will be together forever.
  • He always walks on my left side,
    so I want to arrange a small diamond
    to the left of the diamond.

    that you will never forget.

Make Your Proposal a Memory for a Lifetime

A diamond engagement ring is a symbol of a man's commitment to spend the rest of his life with the woman he loves. Every time she looks at it, she remembers the moment he proposed, the love they share, and the emotions they felt. The ring is not only a testament to their love, but a treasure that will be passed down through generations.

The Eternal Charm of Diamonds

The Miracle Crystal Born in Nature

Diamonds are natural minerals that were born in nature. They were formed deep underground billions of years ago and were pushed up to the surface by volcanic eruptions, which is how they became accessible to humans.

The Symbol of Eternal Love

It takes over three billion years for diamonds to form on Earth. To achieve the dazzling sparkle that captivates people, diamonds require a lot of time and human effort. This includes opening up mines, conducting mining activities, and polishing only the high-grade raw diamonds. Only after going through these processes do diamonds gain their value as gems and shine brightly in front of the couple's eyes.

How rare are diamonds?
On average, a diamond deposit yields about 5 grams (25 carats) of diamonds from 100 tons of kimberlite ore. Only 1 gram (5 carats) of that is said to be of gem quality.

4C

The sparkling brilliance of a round brilliant cut diamond is evaluated based on four clear criteria, known as the 4Cs: Carat weight, Color, Clarity, and Cut. This standard, known as the "4Cs," was proposed by the American Gemological Institute (GIA) in the mid-20th century. Today, 4Cs is adopted as the quality standard for diamonds worldwide, including many well-known high jewelers.
