It should also be UV tested and free from major inclusions. When selecting a square cut ruby for jewelry making, it is important to evaluate its quality based on clarity, cut, color, and durability. A high-quality ruby will not only look beautiful but will also last in a piece of jewelry. As a jewelry maker, I have learned that the clarity of a ruby is one of the most important factors to consider. A VVS (Very Very Slightly Included) ruby is a high-quality option that is free from major inclusions and has a clear, bright appearance. The cut of the ruby is also crucial. A square cut should be even and symmetrical, with well-defined facets that enhance the brilliance of the stone. A poorly cut ruby may look dull or unbalanced, which can affect the overall design of the jewelry. The color of the ruby is another important factor. A vivid red color is the most desirable, as it gives the ruby a rich and luxurious appearance. A lighter or more brownish ruby may not be as valuable or attractive. Finally, the durability of the ruby is important, especially if it will be used in rings or bracelets that are worn frequently. A UV tested ruby is a good indicator of quality and stability.

This will help preserve its brilliance, clarity, and color over time. As a jewelry maker, I have learned that proper care and maintenance are essential for preserving the quality of a square cut ruby. A well-maintained ruby will last longer and look better over time. One of the most important steps in caring for a square cut ruby is cleaning it regularly. I recommend using mild soap and warm water to gently clean the gemstone. Avoid using harsh chemicals or abrasive materials, as they can damage the surface of the ruby. Another important step is avoiding exposure to harsh chemicals. Rubies are not resistant to strong chemicals, such as bleach, ammonia, or chlorine. These can damage the surface of the ruby and reduce its clarity. Proper storage is also important. I recommend storing the square cut ruby in a soft cloth or jewelry box to prevent scratches and keep it away from other jewelry that may cause damage. Finally, it is important to inspect the ruby regularly for any signs of wear or damage. If you notice any cracks, chips, or discoloration, it may be time to have it professionally cleaned or repaired.
