Rare bi-color 2.51ct blue and yellow Sapphire

This large sapphire exhibits a rich yellow hue anchored at the end with an inflection of strong blue saturation creating a color palette that is as unique as a fingerprint. This is accented by a green ribbon of color that travels through the gem where its opposing colors meet. Measuring 8.7mm x 7.2mm x 4.0mm, and having a Mohs hardness rating of 9 out of 10, it is perfect for setting and everyday wear. Beryllium heated only.
