Color Change Garnet 6.7ct Cushion CC 027

A color-change garnet with a weight of 6.7 carats and a cushion cut that transitions from yellowish-green to pinkish-red is a fascinating gemstone. Here’s some information about it:

Type of Garnet: Color-change garnets are typically a variety of garnet known as “alexandrite-like garnets” or “color-change pyrope-spessartine garnets.” These gems exhibit the unique ability to display different colors under various lighting conditions.

Color Transition: The gemstone you described undergoes a color change from yellowish-green to pinkish-red. The yellowish-green tones likely appear under natural daylight or fluorescent lighting, while the pinkish-red hues emerge under incandescent lighting or other warm light sources.

Phenomenon Explanation: This color-change phenomenon is a result of the garnet’s chemical composition interacting with different wavelengths of light. The specific elements present in the garnet, along with its crystal structure, contribute to this optical effect.

Rarity and Value: Color-change garnets are relatively rare and highly valued for their unique optical properties. The intensity of the color change, along with factors such as clarity, cut, and carat weight, influences the gemstone’s value. A larger stone like the one you described, especially with a significant color change, can be quite valuable.

Overall, a 6.7-carat cushion-cut color-change garnet with a transition from yellowish-green to pinkish-red is a stunning and unique gemstone that would be a prized addition to any collection or jewelry piece.
