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

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)

Related product recommendations

Utilizing advanced crystal growth technology, this product replicates the identical Al₂O₃ crystal structure of natural top-grade pigeon blood rubies, exhibiting the signature intense red hue (meeting GIA's pigeon blood standard). Compared to natural gems, it demonstrates superior color saturation (CIE L*a*b: L35-40, a*25-30) and internal purity (VVS grade), while priced at just 1/5-1/10 of natural counterparts. Available in custom cutting sizes (1-50ct rough), ideal for high-end jewelry customization, investment collections, and specialized industrial applications.

FAQ of synthetic royal blue sapphire gemstones

1. Q: What is synthetic royal blue sapphire?

A: Synthetic royal blue sapphire is a lab-grown Al₂O₃ single crystal with identical chemical/physical properties to natural sapphire, featuring superior color consistency (Pantone 19-4053) at 30-50% lower cost.

2. Q: How to identify synthetic vs natural royal blue sapphire?

A: Key identifiers: Synthetic lacks natural inclusions (e.g., rutile needles), shows curved growth striations under microscopy, and exhibits different Fe/Ti ratios in EDX analysis.
