Sapphire Description
Presenting a distinctive 0.55 carat bi-colour Ceylon sapphire, expertly cut in a classic cushion shape and an excellent choice for a unique ring, pendant, or bespoke jewellery design. This gemstone showcases a fascinating blend of blue and white tones, creating a natural contrast that gives the stone an individual and eye-catching character.
Bi-colour sapphires are especially admired for their unusual colour zoning, with each stone displaying its own one-of-a-kind pattern formed naturally within the crystal. The combination of cool blue and crisp white offers a contemporary, versatile look that feels both fresh and elegant.
Having undergone heat treatment, a standard and widely accepted enhancement, this sapphire benefits from improved clarity and overall visual appeal while preserving its natural beauty. Carefully sourced and selected for its unique character, this gemstone offers a charming centre stone for a jewellery creation that celebrates originality, modern style, and understated sophistication.
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
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.
