Purple Ruby
Purple Ruby, sometimes referred to as “Purple Sapphire” or “Purple Corundum”, is a rare and visually striking variety of corundum — the same mineral family to which ruby and sapphire belong. While “purple ruby” isn’t a formal or standard gemstone classification, the term may be used informally to describe ruby or sapphire stones with notable purple hues. This coloration is caused by trace amounts of elements such as chromium (for rubies) or iron and titanium (for sapphires).
Characteristics of Purple Ruby (Purple Corundum):
- Color: The most defining characteristic of purple ruby is its unique shade, which ranges from lavender to deep violet. The color can vary based on the specific elements involved in its formation, and it may include secondary hues such as pinkish or bluish tones.
- Composition: Corundum (Al₂O₃) with trace elements that impart its purple hue. For rubies, this trace element is chromium, while for sapphires, it is typically iron and titanium.
- Hardness: 9 on the Mohs scale, making it one of the hardest natural materials, second only to diamond. This exceptional hardness makes purple ruby incredibly durable and suitable for use in fine jewelry.
- Transparency: Generally transparent to translucent, though higher-quality stones can be quite clear.
- Luster: Vitreous, giving it a brilliant, glass-like shine when polished.
Formation and Occurrence:
Purple rubies or sapphires form in high-temperature and high-pressure environments, typically in metamorphic rocks such as marble or igneous rocks like basalt. The purple color occurs due to specific trace elements present during the crystallization process.
- Ruby: True rubies are colored red by chromium; purple rubies contain both chromium and trace amounts of titanium or iron, giving them a more complex hue.
- Sapphire: Sapphires are typically blue, but when they appear purple, the combination of titanium and iron imparts this distinctive color.
Locations:
Purple rubies or purple sapphires can be found in a few places, including:
- Sri Lanka
- Myanmar (Burma)
- Thailand
- Madagascar
- Montana, USA (where purple sapphires are notably found)
Uses:
- Jewelry:
- Due to its hardness and vibrant color, purple ruby is used extensively in rings, necklaces, earrings, and other fine jewelry.
- It is typically faceted to highlight its brilliance, although some stones are cut into cabochons to emphasize color and clarity.
- Collecting: Due to its rarity and unique coloration, purple ruby is highly sought after by gem collectors.
- Metaphysical Properties:
- Spiritual Growth: Like other varieties of ruby and sapphire, purple ruby is believed to enhance personal strength, stimulate the mind, and provide clarity.
- Emotional Healing: It is associated with stimulating the heart chakra, promoting love and emotional balance, while also connecting to the third-eye chakra to enhance intuition and insight.
Care and Maintenance:
- Cleaning: Clean purple rubies with warm, soapy water and a soft cloth. You can also use a mild gemstone cleaner. Avoid using harsh chemicals or ultrasonic cleaners, as these can potentially damage the stone or its setting.
- Storage: Store separately from other gemstones to avoid scratches, as rubies are extremely hard but can still be scratched by diamonds.
- Handling: While purple rubies are durable, they should be handled with care to prevent any sudden impact, which could cause chipping or breakage, particularly in jewelry.
