The color change nature of this natural sapphire is nothing short of intoxicating. In daylight she shines olive green and grey. It's subtle and sultry. Indoors, she changes her tune to a lively lilac. For me It was love at first sight. This stone was a no brainer for the gentleman who commissioned this ring-- it was mined in his home state of Montana and seemed as unique as his bride-to-be. An 18k mounting and a halo of twinkling diamonds was all it needed to be ready for her hand. He's very happy to report, she said 'yes.'
