Synthetic royal blue sapphire gemstones of product introduction

 

 

 

Synthetic Colored Sapphire Crystal Royal Blue for Custom Jewelry Design​

 

 

 

Synthetic Royal Blue Sapphire Crystal is produced through advanced crystal growth technology with a chemical composition of Al₂O₃. Precise Fe/Ti ion doping achieves stable royal blue coloration (Pantone 19-4053 equivalent), exhibiting Mohs hardness 9, density 3.98-4.02 g/cm³, >90% visible light transmittance, and a 2050°C melting point. Compared to natural gemstones, it offers superior color uniformity (ΔE<1.5), zero internal defects, and customizable processing. Widely used in luxury jewelry (rings/necklaces) and watchcase manufacturing industries.

Core characteristics of synthetic royal blue sapphire gemstones

Synthetic Colored Sapphire Crystal Royal Blue for Custom Jewelry Design 0

 

1. Color Properties

  • Hue: Rich indigo blue (HSV 270-285°) with velvety texture
  • Saturation: CIELAB C* >85, surpassing 95% of natural sapphires
  • Uniformity: Color variation <0.1ΔE (CIE LAB standard)

 

2. Technical Advantages

  • Defect Control: Czochralski method ensures dislocation density <10³ cm⁻²
  • Size Range: 2-15cm diameter ingots, yielding 1-100ct gem-quality material
  • Cost Efficiency: Production cost 1/20–1/50 of natural royal blue sapphire

 

3. Identification Features

  • Spectroscopy: Fe/Ti ratio differs from natural sapphire (natural ≈10:1, synthetic ≈1:1)
  • Inclusions: No natural rutile needles; may contain flux-related platinum platelets
  • Thermal Conductivity: 25 W/m·K (synthetic) vs. 35 W/m·K (natural)
