1.50ct Natural Royal Blue Sapphire Round main view | SARATTI

Description

This natural Sapphire is graded Vivid to Intense Blue by GUILD, with Royal Blue recorded as its trade name. The stone presents a concentrated blue face-up appearance, with brighter electric-blue reflections appearing between deeper areas of colour as the facets interact with light. GUILD states the colour simply as blue without assigning a secondary hue, while the supplied views show a balanced distribution of blue across the round outline.

Fashioned in a Round shape with a Modified Brilliant cut, the Sapphire uses a structured arrangement of crown facets to create alternating flashes of brightness and deeper internal reflection. The nearly circular proportions support an even visual spread, while the central facets develop a broader reflective field surrounded by smaller, more active flashes toward the perimeter. No clarity grade has been supplied, so no eye-clean or clarity designation is assigned.

At 1.50 carats and measuring 6.63 × 6.57 × 4.00 mm, the stone provides a balanced round face-up proportion for a refined centre-stone design. Its Royal Blue colour would work particularly well against platinum or white gold in a solitaire, restrained diamond halo or three-stone composition, while its approximately 6.6 mm spread also makes it suitable for a bespoke pendant or other individually proportioned fine-jewellery design.

September Birthstone

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

Design Invitation

The balanced round outline and concentrated Royal Blue colour make this 1.50-carat Sapphire particularly well suited to platinum or white gold, where the cool metal can create crisp contrast around the blue centre.

A clean solitaire would preserve the approximately 6.63 × 6.57 mm face-up proportions, while a restrained diamond halo or carefully proportioned side stones could introduce additional light without overwhelming the Sapphire.

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