Gemological Properties
The Hardness Scale: Ranking on the Mohs Scale
When it comes to gemstones, including sapphires, one of the key factors to consider is their hardness. Hardness determines a gemstone’s resistance to scratching and abrasion.
The Mohs scale of mineral hardness, developed by Friedrich Mohs in 1812, is a widely used reference for comparing the hardness of different minerals. It consists of ten minerals ranked from softest to hardest, with talc being the softest at number one and diamond being the hardest at number ten.
Sapphires hold an impressive position on this scale with a rating of nine out of ten. This exceptional hardness makes sapphires highly durable and suitable for everyday wear.
Their resilience allows them to withstand daily activities without significant damage or scratches. However, despite their impressive hardness, it is important to remember that even sapphires can still be vulnerable to chipping or cracking if subjected to extreme force or improper handling.
Clarity Characteristics: Natural Inclusions
Natural inclusions are an inherent part of any gemstone’s journey from formation deep within the Earth’s crust. These unique internal characteristics contribute to a gemstone’s individuality and often serve as nature’s signature within each stone. Sapphires typically contain various types of inclusions that vary in size, shape, and position within the stone.
Common inclusions found in sapphires include needles, feathers, color zoning (variation in color intensity), fingerprints (growth marks), and rutile silk (fine needle-like crystals). These inclusions can provide clues about a sapphire’s origin and formation process while also influencing its appearance.
While some inclusions may affect a sapphire’s clarity, they do not necessarily diminish its beauty or desirability. In fact, certain types of inclusions, such as rutile silk, can create captivating visual effects like the star phenomenon in star sapphires.
