I will be showing you a technique for painting a "gemstone". Most of the gemstones I paint are on miniature wargaming models.
With this technique you will be able to draw or paint (on a model, canvas, paper, computer painting program, etc.....) a "gemstone" with a metal base(see picture 1). I used a computer program called "The GIMP" for painting this gemstone.
Picture 2 shows the real thing in five different colors.
Step 1: Getting Started
Start by drawing a gray oval shape. Then draw a dark red oval shape inside the grey oval leaving an even border of gray around the red.
Step 2: Adding to the Color (Giveing It That Transparent Look)
Note: You don't have to use as many different shades of red as I did.
Step 3: Metal Base
Then paint the upper left and lower right sides with a lighter gray than the base color.
Do this step again but with a lighter light color and a darker dark color.(see picture 2) This will make it seem a little bit more shiny.
Step 4: All Done!
The second picture is another gem I drew. I used the same technique as the other one, but I used different colors.
If you have any questions, I will do my best to answer them.
I hope you enjoyed this instructable.
