Determining the origin and treatment of a ruby is an important step in evaluating its value and quality.
The origin of a ruby can significantly affect its price. Rubies from certain regions, such as “pigeon’s blood” ruby from Burma (now Myanmar), are known for their high quality and command a premium price.
To determine the origin of a ruby, gemologists use a combination of scientific testing and visual inspection. One way to identify the origin is to examine inclusions or natural imperfections, as rubies from different regions may have distinct inclusions that help identify their origin. Additionally, gemologists may use spectroscopy to analyze the chemical composition of the ruby and compare it to known samples from specific regions.
