Shipping and returns details Refund policy

This teal natural sapphire combines deep green-blue colour with the crisp geometry of a Dutch marquise cut. Its long, straight sides and pointed ends frame broad step facets, with bands of light that move as you turn the stone.

At 1.92 carats and 11.86 × 6.03 mm face-up, it offers a distinctive centrepiece for a custom ring or a clean-lined pendant. This is one unique stone: the photographs show the exact sapphire you will receive, and its GFCO report accompanies it.

COLOR AND CUT CHARACTER

The appeal is in the contrast: bright green and blue-green reflections sit against deeper teal areas, while the straight stepped facets give the stone a measured, architectural look. It can appear quite dark at some angles, then open into lighter bands as it tilts. The video is particularly useful for seeing that movement.

Its elongated outline could be set along the finger, across it, or vertically in a pendant. A jeweller can help you choose a setting that suits the stone's dimensions and protects its pointed ends.

CLARITY AND SETTING GUIDANCE

The sapphire is slightly included. Small features are visible in the enlarged photographs and video; the between-fingers views also give a useful sense of its scale. Ask your jeweller to inspect the stone before planning the final setting.

PHOTOGRAPHS AND VIDEO

The photographs and video were taken in natural light and show the exact sapphire you will receive. Macro views enlarge small details. Appearance may vary with illumination, viewing angle, surroundings and display settings.
