The Science Behind Ruby’s Hardness and Durability

Introduction

Welcome to our comprehensive guide on the science behind ruby’s hardness and durability. If you are a jewelry enthusiast or someone looking to purchase a ruby piece, understanding the factors that contribute to its durability is essential. In this article, we will delve into the fascinating world of rubies, exploring their composition, hardness, and how they withstand the test of time.

What are Rubies?

Rubies are precious gemstones known for their rich red color and exceptional beauty. They belong to the corundum mineral family, consisting of aluminum oxide with trace amounts of chromium. The presence of chromium is responsible for the vibrant red hue that makes rubies so desirable. Rubies are one of the four precious gemstones, alongside diamonds, emeralds, and sapphires.

The Mohs Scale of Hardness

When it comes to assessing the hardness of gemstones, the Mohs scale is the most widely used method. Developed by Friedrich Mohs in 1812, this scale ranks minerals based on their ability to resist scratches. Rubies have a hardness of 9 on the Mohs scale, making them one of the hardest gemstones available, second only to diamonds, which have a hardness of 10. This exceptional hardness ensures that rubies can withstand everyday wear without being easily scratched or damaged.

Crystal Structure

The crystal structure of ruby also contributes to its durability. Rubies belong to the trigonal crystal system, which means they have a symmetrical three-fold axis. This crystal structure makes them less prone to breakage and enhances their overall strength. The tightly packed arrangement of atoms within the crystal lattice gives rubies their robustness, allowing them to withstand external forces and resist chipping or cracking.

Heat Resistance

Another remarkable aspect of ruby’s durability is its high heat resistance. Rubies can withstand extreme temperatures without significant damage. This property makes them ideal for use in jewelry, especially in settings where heat may be applied during the crafting process. Rubies can withstand temperatures up to 2,000 degrees Celsius (3,632 degrees Fahrenheit) without undergoing any noticeable changes, ensuring their long-term durability.

Treatment and Enhancement

It is important to note that not all rubies possess the same level of durability. Some rubies may undergo treatments or enhancements to improve their appearance or durability. Common treatments include heat treatment to enhance color or the filling of surface-reaching fractures with lead glass to improve clarity. While these treatments can enhance the beauty of rubies, they may also affect their long-term durability. It is crucial to purchase rubies from reputable sources and inquire about any treatments or enhancements before making a purchase.

Caring for Rubies

Proper care and maintenance can significantly prolong the lifespan of your ruby jewelry. Here are some tips to ensure the longevity of your precious ruby pieces:

• Avoid exposing rubies to harsh chemicals or cleaning agents.
• Store your ruby jewelry separately to prevent scratches from other gemstones or metals.
• Regularly clean your rubies using a soft cloth and mild soapy water.
• Remove your ruby jewelry when engaging in physical activities or sports.
• Have your ruby jewelry professionally inspected and cleaned periodically.

Summary

In conclusion, rubies are not only visually stunning gemstones but also possess exceptional hardness and durability. Their composition, crystal structure, high heat resistance, and natural properties contribute to their ability to withstand everyday wear and tear. However, it is essential to be aware of any treatments or enhancements that may affect a ruby’s durability. By following proper care and maintenance practices, you can ensure that your ruby jewelry remains a cherished and timeless piece for years to come.
