Frequently Asked Questions
Is sapphire glass made from real natural sapphires?
No, sapphire glass is a synthetic sapphire crystal. It is created by crystallizing aluminum oxide at high temperatures, resulting in a manmade material with identical physical properties to natural sapphire.
Why is sapphire glass more expensive than standard glass?
The complex manufacturing process and the extreme temperatures required for crystallization make it more costly. However, its unparalleled scratch resistance and durability provide long-term value by reducing replacements.
What is the primary advantage of sapphire glass?
Its core advantage is its exceptional hardness. With a Mohs rating of 9, it is highly resistant to scratches from everyday materials like keys, knives, or sand, maintaining pristine clarity.
Does sapphire glass offer good visibility in different lighting?
Yes, it offers excellent optical transmittance. When combined with anti-reflective (AR) coatings, it ensures perfect readability and visibility in almost any lighting condition.
Is sapphire glass shatterproof and impact-resistant?
High hardness does not equal high impact resistance. Sapphire glass is brittle; while it resists scratches perfectly, severe concentrated impacts may cause it to chip or shatter compared to softer materials.
How is the impact resistance of sapphire components improved?
Resistance is often improved through structural design, such as domed shapes and increased thickness, though avoiding severe direct impacts is still recommended for longevity.
