Ruby gemstones
Ruby gemstones. Rubies are a red variety of the mineral corundum (aluminium oxide). It is the second hardest mineral after diamond, rated 9 out of 10 on the Mohs scale. Artificial rubies are used in industrial lasers and also in analogue watch mechanisms. Inclusions of the mineral rutile (titanium oxide, not seen) cause a six- pointed-star light effect (asterism) to form star ruby

EDITORS COMMENTS
This print showcases the mesmerizing beauty of ruby gemstones. Known for their vibrant red hue, rubies are a type of corundum, an aluminum oxide mineral. Renowned for their hardness, they rank second only to diamonds on the Mohs scale with a rating of 9 out of 10. In this image, multiple cut and polished rubies are displayed in blurred focus, creating an ethereal effect that enhances their allure. While not visible in the photograph, these natural gemstones can exhibit a unique phenomenon called asterism when they contain inclusions of rutile (titanium oxide). This results in a stunning six-pointed-star light effect known as star ruby. Beyond their aesthetic appeal, artificial rubies find practical applications in various industries. They are utilized in industrial lasers due to their ability to emit intense beams of light. Additionally, analogue watch mechanisms often incorporate synthetic rubies for enhanced durability and smooth movement. As we admire this exquisite portrayal of nature's marvels captured by Science Photo Library, let us appreciate the geological wonders found within our planet's depths. These precious gems serve as reminders of Earth's intricate composition and its ability to produce such breathtaking treasures like these ruby gemstones.
