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.

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.
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.
