Sapphire crystals are one of the most popular choices for watch crystals, and for a good reason. They are extremely scratch resistant and also resistant to shattering. In addition, sapphire crystals can be treated with a special coating that makes them even more resistant to scratches and other damage. But first, what are sapphire crystals?
What Are Sapphire Crystals?
Sapphires are precious gemstones that have been treasured for centuries. They are beautiful, durable, and have a wide range of colours, making them perfect for a variety of jewellery designs.
Sapphires belong to the mineral family corundum, which also includes rubies. Corundum is composed of aluminium oxide (Al2O3), a very hard material that makes sapphires resistant to scratching and chipping. The different colours of sapphires are caused by trace impurities in the mineral, such as iron, titanium, or chromium. The most prized sapphires are blue, but they can also be found in a wide range of other colours, including pink, purple, yellow, orange, and green.
While sapphires are often associated with fine jewellery, they also have a number of important industrial applications. Sapphires are used in lasers and scientific instruments because of their durability and optical properties. And, for watch lovers out there, they’re also used on watches!
Sapphire crystals are grown in a lab using the Verneuil method, which involves melting fine aluminium oxide powder in a furnace and then slowly cooling it so that it forms crystals. This process can take up to two weeks, and the resulting crystals are often used in the manufacture of watches, jewellery, and other products.
So, Why Sapphire Crystals?
But one must wonder, why are sapphire crystals even a thing? Why were they created when there are so many other types of crystals out there?
1. Sapphire Crystal Is Incredibly Scratch-Resistant
Sapphire is one of the hardest materials on earth, second only to diamond. This makes it incredibly resistant to scratches, even from everyday wear and tear. If you’re looking for a watch that will keep its good looks for years to come, sapphire crystal is a great option.
2. Sapphire Crystal Is Glare-Resistant
Sapphire crystal has a natural ability to resist glare, making it easier to read the time in direct sunlight. If you’ve ever struggled to read your watch in bright conditions, sapphire crystal can help.
3. Sapphire Crystal Is Shatter-Resistant
While sapphire crystal is not completely shatter-proof, it is much more resistant to shattering than other watch crystals. This makes it a great choice if you’re looking for a watch that can withstand a bit of rough treatment.
4. Sapphire Crystal Is Hypoallergenic
Sapphire crystal is a great choice for those with sensitive skin, as it is hypoallergenic and will not cause irritation.
5. Sapphire Crystal Is Beautiful
Sapphire crystal has a beautiful, lustrous finish that is sure to turn heads. Whether you’re looking for a dress watch or a casual everyday watch, sapphire crystal can add a touch of luxury.
If you’re looking for a high-quality watch that will withstand the test of time, sapphire crystal is a great choice. With its scratch-resistant, glare-resistant, and shatter-resistant properties, sapphire crystal is the perfect material for a durable and good-looking watch.
