Very nice. I love the overall simplicity. Just enough gradient in the back ground to give the amethyst jewel depth and realism. The inside of the jewel is very, very good too. Catching and reflecting light, to get your attention and draw you in.
Thank you for your lovely comment. Jewel is the result of Radial Blur Deluxe with the steps at very low (don't remember what image I used to do that) & then Inside Out, many layer blend modes, colour tint & highlight made on a separate layer & blurred.
Frame is a font that I modified & used Trail plugin.
