Matters needing attention in purchasing red corundum
1, color: The color of red corundum is one of its most important characteristics. The ideal ruby should be bright and full red, such as cherry red or pomegranate red. Avoid colors that are too dark or too pink, because this may be a ruby of lower quality.
2. Transparency: High-quality red corundum should have good transparency. Being able to see bright and clear light through rubies is a good indicator. Avoid choosing rubies with obvious cracks, inclusions or uneven transparency.
3. Cutting: Cutting is very important to show the beauty and sparkle of rubies. Excellent cutting can improve the luster and brightness of ruby. Ensure that the cutting ratio of ruby is reasonable, and there is no obvious asymmetry or distortion. Check whether the ruby is cut accurately and observe whether it produces beautiful refraction and reflection under the light.
4. Purity: The purity of red corundum refers to the inclusions and cracks inside it. A high-quality ruby should have a clear interior and no obvious flaws. Choose rubies without obvious cracks, bubbles or other impurities.
