4.06 Ct. White Sapphire from Ceylon (Sri Lanka)

This transparent 4.06 carat radiant shape white sapphire measures 9.04 x 7.51 x 6.14 mm, and combines precise proportions with an excellent polish to maximize its light return and surface brilliance. Graded as very slightly included at eye level, the stone presents only minor internal characteristics that do not interrupt its overall transparency, and the near colorless intensity offers the clean, luminous appearance prized by collectors and connoisseurs. The radiant cut merges the fire of brilliant facets with the refined outline of step facets, producing scintillation across a broad tabletop while maintaining durable corner protection. Heat treatment has been applied, in line with industry practice, to enhance clarity and stability, and this treatment is permanent and fully disclosed. Origin is Ceylon Sri Lanka, a classic source known for gem bearing metamorphic terrains, and this provenance adds both geological interest and market desirability. The Natural Sapphire Company stands behind accurate grading and transparent disclosure, making this gem attractive to an educated buyer who values documented origin, treatment disclosure, and observable quality factors such as cut, clarity, and polish.

The story of this white sapphire begins millions of years ago deep within the earth, where aluminum rich rocks recrystallized under intense heat and pressure to form corundum, the mineral species that yields sapphires. In Sri Lanka, unique metamorphic conditions and the presence of minimal trace elements allowed a crystal to develop with very low color saturation, resulting in a near colorless appearance rather than the more familiar blue tones. Over geological time the crystal either remained in a primary metamorphic host rock or was liberated by weathering and concentrated in ancient alluvial gravels by river transport and seasonal monsoons. Centuries later, skilled gem hunters recovered the rough, and expert lapidaries shaped it into a 4.06 carat radiant cut that optimizes its natural clarity and light performance. For the discerning purchaser the scientific pedigree matters, from the corundum chemistry and formation environment to the precise cutting and responsible disclosure of heat treatment. This sapphire offers rarity in size, classic Ceylon origin, and aesthetic performance, making it a sound acquisition for an informed collection, and The Natural Sapphire Company is available to provide further documentation and viewing options.
