Mohs Scale of Rubellite Tourmaline

Rubellite Tourmaline is a stunning gemstone known for its vibrant red to pink hues, making it a popular choice for jewelry. When considering this gemstone for everyday wear, it’s essential to understand its hardness and how it compares to other gemstones. The Mohs scale of Rubellite Tourmaline plays a crucial role in determining its suitability for different types of jewelry and how to care for it properly. In this blog, we will explore the Mohs scale of Rubellite Tourmaline, what it means for durability, and how it impacts your choice in jewelry.

Mohs Scale of Rubellite Tourmaline

What is the Mohs Scale?

The Mohs scale is a standard used to measure the hardness of minerals and gemstones, ranking them on a scale from 1 to 10. Developed by Friedrich Mohs in 1812, this scale is based on a mineral’s ability to scratch or be scratched by another substance. The scale is ordinal, meaning that each mineral can scratch those below it on the scale but not those above it.

Mohs Scale of Rubellite Tourmaline

Rubellite Tourmaline ranks between 7 and 7.5 on the Mohs scale, which means it is relatively hard and can resist scratches from many common materials. The Mohs scale indicates that it is harder than some other popular gemstones like opal and turquoise but softer than sapphires and diamonds.

This hardness level makes Rubellite Tourmaline a durable choice for various types of jewelry, including rings, necklaces, and earrings. However, while it is resistant to scratches, it is not completely impervious to damage, especially from harder materials like sapphires (9 on the Mohs scale) and diamonds (10 on the Mohs scale).

Durability of Rubellite Tourmaline

Understanding the Mohs scale of Rubellite Tourmaline is essential for assessing its overall durability. While hardness measures resistance to scratches, durability also considers the gemstone’s toughness (resistance to chipping and breaking) and stability (resistance to heat, light, and chemicals).

  • Hardness: With a Mohs scale rating of 7 to 7.5, Rubellite Tourmaline is hard enough for daily wear but should still be protected from contact with harder materials.
  • Toughness: Rubellite Tourmaline has fair to good toughness, meaning it can withstand some impact but is still susceptible to chipping or breaking if struck hard.
  • Stability: Rubellite Tourmaline is generally stable, but it can be sensitive to sudden temperature changes and prolonged exposure to high heat, which could cause cracking or color changes.

Caring for Rubellite Tourmaline Based on Its Mohs Scale Rating

The Mohs scale of Rubellite Tourmaline provides guidance on how to care for this gemstone to maintain its beauty and longevity. Here are some tips for proper care:

  • Avoid Hard Contacts: To prevent scratches, avoid contact with harder gemstones like diamonds and sapphires. Store Rubellite Tourmaline jewelry separately, ideally in a soft pouch or a lined jewelry box.
  • Clean Gently: Clean Rubellite Tourmaline with warm soapy water and a soft brush. Avoid harsh chemicals or ultrasonic cleaners, especially if the stone has undergone any treatments.
  • Protect from Extreme Conditions: Keep Rubellite Tourmaline away from extreme heat or sudden temperature changes to avoid potential damage. When not wearing the gemstone, store it in a cool, stable environment.
