Development of Fracture Fillers for Enhance Optical Properties in Sapphire Gemstones using Rutile and Quartz
The gem industry lacks durable, non-toxic fracture-filling materials specifically designed for sapphires. Many existing fillers degrade over time, lack stability under heat and pressure, or contain substances that may be hazardous to the environment. A reliable and sustainable solution is essential to maintain the integrity and value of treated sapphires.
Objectives
- Develop a transparent, durable, and stable TiO₂-SiO₂ based fracture-filling material.
- Ensure compatibility with various gemstones
- Maintain the gemstone’s optical and physical properties.
- Enhance the gemstone’s value by improving clarity and durability.
