Color Transitions of Natural Stones in Jewelry: Chemical Processes

The unique color transitions that natural stones exhibit in jewelry are created by the various chemical elements they contain and the interaction of these elements with light. For example, the purple color of amethyst is determined by the way the iron element in the stone absorbs light. Similarly, the blue-green tones of turquoise are due to the copper components in its content. In addition, some stones exhibit properties such as pleochroism , which causes light to appear different colors from different angles.

The Role of Elements

• Iron : Creates purple and yellow tones in stones such as amethyst and citrine.
• Copper : Determines the blue-green tones of turquoise.
• Chromium : Causes green tones in stones such as emerald and jade.

Impact of Geological Processes

Chemical changes and heat-pressure effects that occur during the formation of stones also shape color transitions. These processes change the structure of the mineral components within the stone, creating unique patterns and colors.

This aesthetic aspect of natural stones in jewelry allows them to add value to both works of art and personal accessories.
