In the month of sapphires, we delve into the world of these beautiful gemstones, focusing on the enhancement process of heated sapphires in Chanthaburi, Thailand.

Sapphires, naturally created gemstones, have been a source of fascination for centuries. Today, they are enhanced using high-temperature heating methods, a common practice in the sapphire enhancement industry. This process significantly improves the color and clarity of sapphires, resulting in a higher selling price.

Each sapphire enhancement factory in Chanthaburi has its unique methods for temperature increase and time intervals. While the traditional method involves using a gas furnace, modern low-temperature heating is done using programmed furnaces. The cost of heating sapphires, less than $400 per kilogram, does not significantly affect their selling price.

Chanthaburi, once the center of global sapphire and ruby mining, now processes stones from around the world. Despite the depletion of local mines in the 1980s, when 30% of the world's sapphire and ruby mining was concentrated in Chanthaburi, the region continues to play a significant role in the sapphire industry.

The chance of buying a heated sapphire as an unheated one, if purchased wisely, is practically zero. High-temperature heated sapphires are easily detectable by laboratories. However, the company or person traditionally heating sapphires in a gas oven in Chanthaburi and known for the traditional method of sapphire core heating is not publicly specified in widely available sources.

The increased selling price of heated sapphires reflects their improved quality. The heating process does not alter the chemical composition of sapphires, ensuring their durability and long-lasting beauty.

In conclusion, the enhancement of heated sapphires in Chanthaburi, Thailand, plays a vital role in the global sapphire industry. With its rich history in sapphire mining and unique enhancement techniques, Chanthaburi continues to be a significant player in the world of sapphires.
