The color change in rubies is primarily due to the presence of trace elements like chromium and iron in the gemstone. When the ruby is exposed to different light sources or environments, these elements can interact with light in a way that alters the perceived color of the stone. Temperature changes can also sometimes affect the color appearance of rubies.
What else can I help you with?
Are rubies always red or do they change colors?
Rubies are typically red due to the presence of chromium in their composition. However, some rubies may exhibit different hues such as pink or purplish-red depending on the levels of certain trace elements present. Generally, red is the most sought-after and valuable color for rubies.
What element is responsible for the red color in rubies?
The element responsible for the red color in rubies is chromium. Chromium ions in the crystal lattice of corundum (which is the mineral group that includes rubies and sapphires) cause the red color by absorbing certain wavelengths of light.
What are rubies composed of?
Rubies are composed of the mineral corundum with trace amounts of chromium that give them their vibrant red color. The presence of chromium in the crystal structure is responsible for the red hue seen in rubies.
The red color of rubies is due to the presence of chromium ions physical or chemical?
The red color of rubies is due to the presence of chromium ions in the crystal structure. Chromium ions replace aluminum ions in the crystal lattice of the mineral corundum, giving rubies their red hue. This is a chemical property of the gemstone.
How does paramagnetic color change occur in materials?
Paramagnetic color change in materials occurs when the material is exposed to a magnetic field. This causes the alignment of the material's magnetic moments, resulting in a change in its optical properties and color.
What is a rubies mineral class?
Rubies are a color variant of the mineral corundum, which is an oxide.
Which of gems is red in color?

Can rubies be green?
Yes, rubies can be green. Green rubies are rare and are typically a result of the presence of chromium impurities in the gemstone. These green rubies are often referred to as "chrome rubies" due to the chromium content giving them their green color.
How do rubies get their color?
The red color is caused mainly by the presence of the element Chromium.
What causes the stars seen in star sapphires and star rubies?
See the related links for a website that has a lot of stuff about star sapphires and rubies!
What are rubies composed of?
Rubies are composed of the mineral corundum with trace amounts of chromium that give them their vibrant red color. The presence of chromium in the crystal structure is responsible for the red hue seen in rubies.
What type of weathering makes iron change colors?
oxidation causes iron to change color. oxidation causes rust.
Are cut or uncut rubies worth more?
Uncut rubies are generally worth less than cut rubies because the cutting process adds value by enhancing their brilliance and color. Cut rubies are also easier to set into jewelry and more desirable to consumers for their finished appearance.
What is a mineral class?
Rubies are a color variant of the mineral corundum, which is an oxide.
