Carefully sourced and selected for its unique character, this sapphire presents a striking centrepiece for a jewellery creation that reflects originality, modern style, and understated elegance.
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.

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.
