Sapphire Description
Presenting a refined 1.16 carat blue Ceylon sapphire, unheated and precisely cut in a striking octagon shape, offering a sophisticated balance of modern geometry and natural elegance. This gemstone displays a deep, vivid blue tone with excellent clarity and strong visual presence, making it an exceptional choice for a bespoke sapphire ring or fine jewellery design.
The octagon cut enhances the sapphire’s structure and light performance through its clean step facets, creating a crisp, mirrored effect that draws the eye into the stone’s natural depth. Its symmetrical form brings a contemporary edge while maintaining a timeless sense of refinement.
Being completely unheated, this sapphire holds added rarity and significance. It remains in its pure, natural state without enhancement, preserving its original character and making each visual nuance entirely unique. This untouched quality adds both desirability and long-term value for collectors and fine jewellery connoisseurs alike.
Carefully selected for its quality, origin, and integrity, this Ceylon sapphire is a distinctive centrepiece for a design that values authenticity and understated luxury.
Imaging Accuracy
Imaging Accuracy
We understand that it can be hard to assess loose sapphires colours from photos alone. All our images and videos are taken by a specialist gemstone imaging company who produce images to 99% colour accuracy with ISO standard natural daylight in high magnification. This ensures you will get the best view for colour, clarity and any visible inclusions.
Whilst this is the most accurate representation of the stones colours, sapphire colours vary depending on the lighting conditions.
Certification

Clarity Rating
Clarity Rating
While some sapphires can appear "eye-clean" (meaning no inclusions are visible to the naked eye), most natural sapphires do contain inclusions, which are considered natural characteristics and not necessarily flaws.
Our sapphires are graded in the below format:
VVS (Very Very Slightly Included):These sapphires have very, very small inclusions that are difficult to see even under 10x magnification.
VS (Very Slightly Included):These sapphires have minor inclusions that are clearly visible under 10x magnification, but they might be difficult to see with the naked eye.
SI (Slightly Included):These sapphires have noticeable inclusions that are easy to observe under 10x magnification, and some may be visible to the naked eye.
I (Included):These sapphires have obvious inclusions that are easily visible under 10x magnification and may affect transparency and brilliance.
