Adobe Illustrator: Vertical- View Diamond Trace

 
 I made the diamond by tracing a half-diamond that I downloaded.  I traced it with the Pencil and Line Segment tools. I then copied,reflected,and grouped.  I then added a gradient with the Live Paint Bucket. I added the sparkle with I made using the star tool. I then grouped and lowered the Opacity the diamond.

For the Back ground I used the Rectangle tool with black fill. I went to Google image and got the NY scenery. I added a outer glow to the NY scenery. I placed it on top the black background. I also pasted the diamond , and used the text tool.

I then opened  a Rectangle with black fill used two different filters destort ->.zig- zag and stylize-->drop shadow. I then change the color to white and placed it in the background of the Gem Expo image.
