10.89ct Natural Santa Maria Aquamarine octagonal front view | SARATTI

Description

This Natural Santa Maria Aquamarine displays a vivid blue colour with a luminous, evenly expressed face-up presence. Its cool blue tone remains visible across the broad central area and becomes deeper around the clipped corners and outer facets. GUILD records the trade name as Exceptional Santa Maria Color and awards the stone the special comment Vibrant-brilliance.

Fashioned in an octagonal shape with a step cut, the gemstone presents a strong architectural outline defined by straight sides and precisely clipped corners. Its parallel facet arrangement produces broad linear reflections rather than scattered flashes, creating measured light movement, visible internal depth and a composed geometric character.

Weighing 10.89 carats and measuring 16.58 × 11.45 × 7.78 mm, this Aquamarine offers substantial scale and balanced rectangular proportions for an important centre-stone jewel. Its vivid blue colour and structured outline would suit a statement ring, cocktail ring, pendant or bespoke 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 stone, and have the setting inspected periodically to ensure the gemstone remains secure.

Design Invitation

The gemstone’s vivid blue colour, octagonal outline and commanding 10.89-carat scale would sit naturally within platinum or white gold, while yellow gold would introduce a warmer architectural contrast. It may be acquired loose or developed through SARATTI’s bespoke jewellery service.
