Sapphire Description
Presenting a distinctive 0.72 carat bi-colour Ceylon sapphire, expertly fashioned in an elegant oval cut and well suited for a unique ring, pendant, or bespoke jewellery design. This gemstone showcases a striking blend of blue and yellow tones, creating a natural contrast that gives the stone both vibrancy and individuality.
Bi-colour sapphires are especially valued for their unique colour zoning, with each stone displaying its own natural pattern formed deep within the earth. The combination of cool blue and warm yellow offers a lively, dynamic appearance that shifts subtly with light, making this sapphire particularly eye-catching.
Carefully sourced and selected for its character, this gemstone offers a standout centrepiece for a jewellery creation that reflects creativity, originality, and contemporary 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.
Certification

Certain stones may include extra certification by GIA or SSEF Switzerland, this will be highlighted in the description. Please do contact us if you wish to discuss any certifications.
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.
