1.50ct Natural Royal Blue Sapphire Cushion main view | SARATTI

Description

This natural Sapphire presents a concentrated vivid blue face-up appearance, with Royal Blue recorded as the trade name by GUILD. Across the stone, the blue remains strongly defined, with brighter flashes appearing through the outer facets while a deeper blue field develops through the centre, giving the gemstone a distinct and composed colour presence.

Cut into a cushion shape with a Modified Brilliant faceting style, the stone combines softened corners with a slightly elongated outline. Its angular facet arrangement produces broad reflective flashes across the crown, while the deeper central area creates visible internal depth and contrast as the gemstone changes position under light.

At 1.50 carats and measuring 7.19 × 5.47 × 3.83 mm, the elongated cushion proportion offers useful face-up length for a refined centre-stone design. Its Royal Blue colour can work particularly well in platinum or white gold, either as a structured solitaire, a three-stone ring with diamond sides, a considered halo composition, or a bespoke pendant where the cushion outline remains clearly visible.

September Birthstone

Sapphire is the traditional birthstone for September and is also associated with the 5th and 45th wedding anniversaries. Its broad range of recognised colours has made Sapphire an established gemstone for both traditional and contemporary fine jewellery.

Design Invitation

The concentrated Royal Blue colour of this 1.50-carat cushion Sapphire would pair naturally with the crisp contrast of platinum or white gold. A structured solitaire can keep the elongated cushion outline central, while tapered diamond sides or a restrained diamond halo can add definition without overwhelming its proportions.

The gemstone may be acquired loose or developed through SARATTI’s bespoke jewellery service into a design created specifically around its 7.19 × 5.47 mm face-up dimensions.
