15.77ct Natural Santa Maria Aquamarine octagonal front view | SARATTI

Description

This Natural Santa Maria Aquamarine presents a vivid blue colour with a bright, commanding face-up presence. The blue remains clearly expressed across its elongated outline, appearing lighter through the broad central field and more concentrated around the clipped corners and outer facets. GUILD records the trade name as Exceptional Santa Maria Color and awards the special comment Vibrant-brilliance.

Fashioned in an elongated octagonal shape with a step cut, the gemstone is defined by straight sides, balanced clipped corners and a precise architectural profile. Its parallel facet arrangement creates broad linear reflections and controlled flashes of blue and white light, while the deeper perimeter facets frame the open central area with measured contrast.

Weighing 15.77 carats and measuring 18.87 × 11.82 × 9.46 mm, this Aquamarine offers substantial scale and impressive face-up proportions for an important centre-stone jewel. Its long geometric silhouette would suit a statement ring, cocktail ring, signature pendant or individually commissioned composition in platinum, white gold or contrasting yellow gold.

March Birthstone

Aquamarine is recognised as the traditional birthstone for March. Its blue to green-blue colour range gives the Beryl family a calm and open visual character, with individual stones varying in tone, saturation, transparency and internal detail.

Aquamarine Care

Clean with warm, soapy water and a soft brush. Avoid sharp impact and sudden temperature changes. Use secure prongs, a protective bezel or guarded corners for this angular step-cut gemstone, and have the setting inspected periodically to ensure the gemstone remains secure.

Design Invitation

The gemstone’s vivid blue colour, elongated octagonal outline and impressive 15.77-carat scale would pair naturally with platinum or white gold, while yellow gold would create a warmer contrast around its structured silhouette. It may be acquired loose or developed through SARATTI’s bespoke jewellery service.
