Our Products:

• Colored Diamonds

As the name implies, colored diamonds are diamonds that are naturally colored, authentic diamonds. It is very difficult to show the true color and brilliance of a diamond through pictures. Colors on the website often differ depending on the environment, in which the diamond is viewed on the computers. We would like to avoid possible misconceptions, such as “the actual color of a purchased diamond is different from what is shown on the website.” Therefore, we highly recommend our customers to visit our office to see our products in person before purchasing if possible. We have a variety of colored diamonds, and we are confident that you will find colors you have never seen before. You may also be one of the first to see some of the diamonds before they appear on our website.

　

　

• Uniquely Shaped Diamonds

We have many uniquely shaped diamonds that are hard to find anywhere else.
You can see the precision of the cut as well as the high quality of the design in person, which are difficult to see in pictures. As reflections sometimes make it hard for you to see every detail of a cut, we recommend our customers to come into our office to check out our products in person.

In addition to offering colored diamonds and rare set stones, we provide consultation on the custom-made jewelry, such as rings and necklaces. Please feel free to contact us for more information. 。
