April birthstone

The birthstones for April are diamond and morganite .

Diamonds are considered the standard for engagement rings and wedding rings. I think there are many women who admire the strong shine that is unique to diamonds. In fact, diamonds come in many colors, including yellow, brown, pink, orange, blue, and red, in addition to colorless diamonds. Depending on the color and size, many diamonds are traded for hundreds of millions of yen at famous auctions around the world due to their rarity.

Morganite is the name given to pink beryl. Beryl is called different names depending on the color, with the green emerald and blue aquamarine being particularly famous. It has a range of colors from bluish pink to orange-ish pink, so you can enjoy a variety of pink colors. Large crystals can also be harvested, so it is a gemstone that can be enjoyed by its size and cut.
