1.53ct Natural Royal Blue Sapphire Cushion main view | SARATTI

Description

This natural Sapphire carries a concentrated blue presence, with Vivid Blue recorded as the colour grade by GUILD and Royal Blue confirmed as its trade name. Face-up, the colour moves between a deeper central blue field and brighter blue reflections toward the perimeter, giving the stone pronounced tonal contrast without losing its strongly defined blue identity.

The gemstone is fashioned into a softly squared Cushion shape with a Modified Brilliant cut. Broad angular facets create distinct flashes across the crown, while the rounded corners soften the outline and maintain a balanced rectangular proportion. The deeper central area provides visual depth, with brighter facet reflections becoming more apparent as the viewing angle changes.

At 1.53 carats and measuring 7.36 × 5.79 × 3.55 mm, this Sapphire offers a slightly elongated cushion proportion that can translate naturally into a refined centre-stone composition. Platinum or white gold would provide crisp contrast with its Royal Blue colour, while a structured solitaire, three-stone arrangement, restrained diamond halo or bespoke pendant could preserve the character of the cushion outline.

September Birthstone

Sapphire is the traditional birthstone for September.
It is also associated with the 5th and 45th wedding anniversaries.
Its broad colour range allows Sapphire to remain relevant across traditional and contemporary fine-jewellery designs.

Design Invitation

The Royal Blue colour and slightly elongated cushion proportion of this 1.53-carat Sapphire lend themselves particularly well to platinum or white gold. A clean four-prong solitaire would keep the outline prominent, while tapered diamond sides or a restrained halo could add structure around the 7.36 × 5.79 mm face-up dimensions.

The gemstone may be acquired loose or developed through SARATTI’s bespoke service into a ring, pendant or individual fine-jewellery composition designed specifically around its proportions.
