So Abbiegoth asked me if I could make a tutorial of how I color and do lighting on gems/jewels. Here we go.
biggest key to understanding gems is that
- Gems are not flat, they are 3d shapes, so treat them as such
- Gems are translucent, not transparent. light goes in one side and out the other, but it illuminates the object WHILE passing in and passing back out, and the in-ray creates a smaller point of light than the outside because light scatters inside the gem.
- subtlety with any sort of outer glow is key. gems are deep, not glowsticks, subtlety can help make jewels and gems deep and have lots of personality, so make sure you have your dark depths and subtle lights. dont abuse glows, use them as the cherry on top.
Hope this helps a little, and thanks for the question
