July birthstone
July's birthstone is Ruby Sphene .
Ruby can be said to be the representative of red gemstones. It is a gem that has been loved all over the world since ancient times. In fact, it belongs to the same mineral corundum as the striking blue sapphire. Corundum is said to be the second hardest material after diamond, and due to its durable properties, it can be enjoyed as everyday jewelry. The stronger the red and the more vivid the color, the more valuable it is, and the highest quality is called "pigeon blood."
Sphene is a gemstone that is also known for emitting dispersed light (fire) that is stronger than diamond. One of its characteristics is that it is highly pleochroic, showing different hues depending on the viewing angle. Depending on the angle of light, fire and pleochroism can appear at the same time, giving it an enchanting beauty that captivates the viewer.
