NATURAL STAR SAPPHIRE - OVAL CABOCHON CUT

A FINE EXAMPLE OF A NATURAL STAR SAPPHIRE, EXPERTLY CUT IN THE TRADITIONAL OVAL CABOCHON FORM TO MAXIMISE THE DISPLAY OF ASTERISM. THE STONE EXHIBITS A PRONOUNCED SIX-RAYED STAR EFFECT THAT MOVES DYNAMICALLY ACROSS THE POLISHED SURFACE AS LIGHT SHIFTS, A CHARACTERISTIC OPTICAL PHENOMENON CAUSED BY THE ALIGNED RUTILE NEEDLE INCLUSIONS WITHIN THE CORUNDUM CRYSTAL STRUCTURE.

GEMSTONE SPECIFICATIONS:
- TYPE: NATURAL CORUNDUM (SAPPHIRE)
- COLOUR: DEEP BLUE-BLACK WITH STRONG STAR EFFECT
- CUT: OVAL CABOCHON
- OPTICAL EFFECT: SIX-RAYED STAR (ASTERISM)
- SURFACE FINISH: HIGHLY POLISHED WITH EXCELLENT LUSTRE

CONDITION: THE STONE IS IN EXCELLENT CONDITION WITH NO CHIPS, CRACKS, OR SURFACE ABRASIONS. THE POLISHED DOME SURFACE IS CLEAN AND FREE FROM SCRATCHES. THE STAR EFFECT IS SHARP AND WELL-DEFINED, INDICATING PROPER ORIENTATION AND CUTTING OF THE ROUGH MATERIAL. NO EVIDENCE OF HEAT TREATMENT OR ENHANCEMENT IS APPARENT FROM VISUAL INSPECTION, THOUGH GEMOLOGICAL TESTING WOULD BE REQUIRED FOR DEFINITIVE CONFIRMATION OF TREATMENT STATUS.

PRESENTATION: ACCOMPANIED BY A GEMOLOGICAL REPORT DETAILING THE STONE'S CHARACTERISTICS, ORIGIN ASSESSMENT, AND TREATMENT STATUS. THE REPORT CONFIRMS NATURAL CORUNDUM COMPOSITION AND DOCUMENTS THE ASTERISM EFFECT.

NATURAL STAR SAPPHIRES OF THIS QUALITY AND SIZE ARE INCREASINGLY SOUGHT BY COLLECTORS AND JEWELLERY DESIGNERS. THE COMBINATION OF DEEP COLOUR SATURATION, SHARP STAR DEFINITION, AND CLEAN TRANSPARENCY MAKES THIS AN EXEMPLARY SPECIMEN FOR EITHER FINE JEWELLERY SETTING OR SERIOUS GEMSTONE COLLECTION.
