Personal Note From Natural Gems Belgium:

This 1.25 ct oval cut sphene gemstone sparkles reddish orangy green in normal daylight and exhibits multiple colors of sparkle in direct light. Its cut grade is fair to good, symmetry is fair to good, and polish is fair to good, given its level of difficulty. The luster is also bright and adamantine.
