1.50 Ct. Purplish Blue Sapphire from Ceylon (Sri Lanka)

This transparent 1.50 carat cushion shape purplish blue sapphire measures 5.98 x 5.43 x 4.81 mm, and is faceted with a mixed brilliant cut that balances scintillation and depth of color. The stone exhibits intense color intensity and an excellent polish, attributes that enhance its presence in a variety of mounting styles. Clarity is graded as slightly included when evaluated at eye level, which means the inclusions are natural and unobtrusive to the unaided eye while still supporting a lively and saturated color. The sapphire has been heat treated, a stable and widely accepted enhancement used to refine color and clarity, and its origin is Ceylon Sri Lanka, a source known for producing sapphires with refined hue and lively saturation.

As an engagement gemstone this sapphire offers a strong combination of aesthetic appeal and practical performance. Corundum has a Mohs hardness of nine, second only to diamond, making it highly resistant to everyday wear and well suited for a ring that will be worn daily. The cushion shape provides a timeless silhouette that reads as both classic and contemporary, and the mixed brilliant cut is designed to maximize brilliance and light return while preserving the stone weight in an elegant profile. The intense purplish blue hue presents a distinctive alternative to traditional blue sapphires, offering depth and personality while remaining versatile with metal choices and diamond accents. Slight inclusions add to the stone's individuality and do not detract from durability or visual impact in typical engagement settings.

For setting and design considerations, the exact dimensions and pavilion depth are well suited to a variety of prong, halo, or bezel mountings, and the mixed brilliant cut performs exceptionally when paired with well proportioned accents to emphasize fire and sparkle. Heat treatment is permanent under normal wear conditions and is a standard practice that enhances the stone without affecting structural integrity. Sourced from Ceylon Sri Lanka and finished to an excellent polish, this sapphire combines provenance, craftsmanship, and material performance. The Natural Sapphire Company can provide full gemological details and guidance on setting options to ensure the stone is mounted in a way that optimizes both visual presence and long term wearability.
