Sapphire Description
Presenting a striking 1.07 carat royal blue Ceylon sapphire, expertly heat treated and finely cut in a classic cushion shape, offering a rich balance of depth, brilliance, and timeless elegance. This gemstone displays a strong, velvety royal blue tone with excellent saturation, making it a superb choice for a sapphire ring or bespoke fine jewellery design.
The cushion cut enhances the stone’s colour and light performance through its softly rounded edges and broad facets, creating a warm, elegant glow with excellent scintillation. Its proportions allow the sapphire’s natural intensity to shine through while maintaining a refined and balanced appearance.

Carefully selected for its quality and presence, this royal blue Ceylon sapphire is a timeless centrepiece suited to elegant, enduring jewellery designs.
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.

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.
