1.61ct Unheated Natural Royal Blue Sapphire Round main view | SARATTI

Description

This natural Sapphire carries a Vivid to Intense Blue colour grade, with Royal Blue recorded as its trade name by GUILD. Face-up, the blue appears strongly saturated and concentrated, with brighter blue reflections moving through deeper areas of colour as the stone meets the light. The round outline gives the colour a balanced field, allowing the Royal Blue identity to remain central to its appearance.

Fashioned in a Round shape with a Modified Brilliant cut, the gemstone uses numerous angular facets to create alternating areas of brightness and deeper internal reflection. The crown structure produces lively flashes around the perimeter while the centre retains a stronger sense of depth, giving the stone visual dimension without relying on an unsupported clarity assessment.

At 1.61 carats and measuring 6.03 × 5.95 × 5.31 mm, the Sapphire offers a compact, well-defined round face-up proportion suited to a refined centre-stone design. Its Royal Blue colour would pair naturally with platinum or white gold in a solitaire, a restrained diamond halo or a balanced three-stone ring, while the same proportions could also translate elegantly into a bespoke pendant.

September Birthstone

Sapphire is the traditional birthstone for September and is also associated with the 5th and 45th wedding anniversaries. Its established place in fine jewellery extends across blue and other recognised Sapphire colours.

Design Invitation

The concentrated Royal Blue colour and balanced round outline make this Sapphire particularly suited to a crisp platinum or white-gold setting. A refined solitaire could keep the colour completely central, while a restrained diamond halo or paired side stones could introduce additional light around its 6.03 mm face-up width.

The gemstone may be acquired loose or developed through SARATTI's bespoke service into a design created specifically around its proportions and colour.
