Synthetic Colored Sapphire Rough gemstones Canary Yellow/Earth Yellow/LV Color

• Composition & Structure​​

1. Laboratory-grown sapphire (Corundum) is chemically composed of pure aluminum oxide (Al₂O₃), synthesized via advanced crystal growth techniques such as the ​​Czochralski method​​ or ​​hydrothermal synthesis​​. Its hexagonal crystal system exhibits a Mohs hardness of 9, second only to diamond.
2. ​​Color Formation​​: Controlled doping with trace elements (e.g., Fe, Ti, V) stabilizes distinct hues—​​LV (light lavender)​​, ​​yellow​​ (chromium/nickel-induced), and ​​beige​​ (iron-induced).

• ​​Optical Properties​​

1. ​​High Translucency​​: >85% visible light transmittance, with a dispersion value of 0.018, producing soft spectral colors.
2. ​​Low Dispersion & Brightness​​: Optimized for circular or oval cuts to maximize light reflection and visual impact.

• ​​Physical Properties​​

1. ​​High-Temperature Resistance​​: Melting point of 2040°C, suitable for high-temperature jewelry applications.
2. ​​Abrasion Resistance​​: Exceptional durability due to its hardness, maintaining luster over extended wear.

Synthetic Colored Sapphire Canary Yellow Unique Features​

​​1. Color Customizability​​

• Adjusting growth parameters (temperature gradients, precursor ratios) enables precise tuning of LV (pale lavender-gray), yellow (golden luster), and beige (earthy tones) shades.

2. ​​Crystal Quality​​

• ​​High Clarity​​: Lab-controlled environments eliminate natural inclusions, ensuring pristine crystal interiors.
• ​​Size Flexibility​​: Cultivates large rough stones (≥20 mm diameter), accommodating complex cutting techniques.
