Note: Lab-created Sapphires, are gemstones grown in laboratories with human aid under controlled environments. They have identical chemical compositions to their natural counterparts (Al2O3) and the same optical and physical properties.
 Lab-grown sapphires are valuable for two reasons of reasons. First, they are very durable – often more durable than naturally-mined sapphires. Second, they tend to have a deep, rich color that is very saturated and evenly distributed. This is often difficult to find in naturally-mined sapphires.
