1.50ct Natural Royal Blue Sapphire Cushion main face-up view | SARATTI

Description

This natural Sapphire is identified by AIGS with a Vivid Blue colour and has been awarded the Royal Blue grade on the AIGS Sapphire Color Grading Scale. Its face-up appearance carries a concentrated blue field, with brighter blue reflections moving through deeper areas as the stone changes orientation. The colour remains strongly present across the cushion outline, giving the gemstone a defined and composed visual character.

Fashioned in a Cushion shape with a Faceted cut, the stone combines gently rounded corners with an elongated rectangular proportion. Its facet arrangement creates angular flashes through the crown while areas of deeper blue provide internal contrast and depth. The supplied views show changing patterns of reflected light across the surface without requiring an unsupported clarity assessment.

At 1.50 carats and measuring approximately 6.29 × 5.03 × 5.17 mm, this Sapphire offers an elongated cushion proportion with considerable depth. Its Royal Blue colour would pair particularly well with platinum or white gold in a structured solitaire or carefully proportioned diamond-accented design, while its compact dimensions could also translate elegantly into a bespoke pendant.
