Natural Big Orange Sapphire 6.82ct Octagon Cut 17.2x7.5mm

This large elongated orange sapphire presents a striking warm colour in a bold octagon cut measuring 17.2x7.5mm. The stone glows with a rich amber-orange warmth, the colour deepening toward the centre and lightening toward the edges to produce an attractive tonal range across the step-cut facets. The elongated shape is highly distinctive, giving the stone a dramatic, architectural presence unlike a standard oval or round. Some natural inclusions are visible within the body, adding genuine character to this substantial natural corundum.

Orange sapphires are among the most unusual and sought-after members of the corundum family, celebrated for their warm autumnal palette that sits midway between golden yellow and fiery orange-red. This stone has been treated with beryllium diffusion to develop and enhance its warm orange colour, a permanent process widely accepted in the sapphire trade. At 6.82ct and 17.2mm long, it is an excellent centrepiece for bespoke statement rings, elongated pendants, and custom jewellery designs where a bold, warm-coloured sapphire in an unusual shape is the goal.
