4.24 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This cushion shape blue sapphire of 4.24 carat presents a balanced combination of proportion and presence, with dimensions of 10.65 by 9.09 by 4.70 mm and a mixed brilliant cut that optimizes return of light. The gem is transparent, with an intense color intensity that displays a deep, vivid blue across the crown and pavilion. Clarity is graded as very very slightly included evaluated at eye level, allowing for strong visual purity while retaining natural character. The polish is excellent, yielding crisp facet junctions and lively scintillation under direct light. The stone has been heat treated, a standard and stable enhancement for sapphires that refines tone and saturation without compromising durability. Origin from Ceylon Sri Lanka contributes to the piece character, reflecting classic material known for its vibrant blue hues and fine gemological qualities.

Owning this sapphire is an investment in beauty and craftsmanship that extends beyond its immediate visual appeal. The combination of weight and quality makes it suitable for a range of settings, from a refined solitaire to a bespoke design that highlights its cushion outline and mixed brilliant faceting. The consistent saturation and excellent polish ensure the gem will remain visually compelling in both daylight and evening lighting, while the secure and permanent nature of corundum supports long term wear. As a provenance based offering from The Natural Sapphire Company, this stone benefits from careful selection and documentation, a factor that enhances its desirability for collectors and designers alike. The heat treatment is disclosed transparently, and the measured proportions provide a reliable basis for planning a setting that preserves table brightness and pavilion depth. In practical terms the sapphire represents a durable, timeless component for fine jewelry, capable of retaining aesthetic and monetary value with proper care. For those who value substantive quality and measured provenance, this 4.24 carat Ceylon sapphire embodies a considered investment in both the artistry of gem cutting and the enduring appeal of natural blue sapphire.
