Miniature Painting Glass Effect (Gemstones) is Easy to Do!

    One of the coolest effects you can paint on a miniature is a glassy, reflective surface like that of a gemstone, eye lenses, goggles, etc. The thing is, it’s also really easy to do on a miniature and it has a big impact.

    I’m going to show you how you can do a miniature painting glass effect easily! There’s just a few basic principles you need to follow to create the effect and it can be done by beginner painters. I also have an advanced technique I show as well.

    Miniature Painting Glass Effect

    I’ll break this down into beginner and advanced. The great part is once you’re comfortable with the beginner technique for the miniature painting glass effect you can easily convert that into the advanced version. You’ll see.

    I’m going to be using Cubie for this tutorial and painting it larger than you would have on a typical miniature. I want you to be able to see the concept larger to understand it easier.

    Despite painting larger, the process remains unchanged on a miniature. Well, let’s be honest, it’s a bit harder on a miniature do to the size.

    However, it’s that small size that makes it easier. The reason I say that is because you don’t have to work so hard to blend things together. Just basic layering for a gem or lense will still look great at a distance; no fancy blending required.

    Light Source Help

    I put together a quick image to show you how things differ based on the angle of the light.

    Light sources on gems

    You can see how the reflection point (covered later) is where the light source is. Also notice that the darkest area of the gem is where the light source is and it gets brighter as it moves away from the light.

    Beginner Miniature Glass Effect

    Even if you’re after the advanced miniature painting glass effect, do read through this section as I explain the theory behind the choices being made and it will help you understand the approach.

    Time needed: 3 minutes

    Beginner’s guide to a glass effect. Further below is the advanced version.

    1. Laying Down the Base Coat

      I like to start by putting down the darkest color I’ll be using as my base coat.

      Now, when you’re doing something highly reflective like this, you have to go darker than you might think. To sell the glass effect you have to really push the contrast as reflective items have a lot of contrast in real life. It’s that high contrast that makes it seem reflective.

      I’m going to paint this red, so for my darkest color I’m going to use a dark brown, in this case Rhinox Hide.

      I kinda forgot to get a picture before I jumped to the second layer. So, jump down a bit. It’s not like it was anything major.

    2. The Second Layer

      To start selling the glass effect I make a jump in my next color. Again, I want to push contrast. So, I’m going to go straight to a red. For this I’ll be using Khorne Red, which is one of my favorite colors.

      What you need to understand with a glass effect is that the darkest color is closest to the light source and you’re brighter colors are furthest from it. I know it seems counter-intuitive but that’s how it works.

      I put down a layer of the red on the lower half of the gem I’m painting. I start about halfway up and bring it down.

      Gems 01

      You can already see the striking contrast. Also, notice how it has a slight curve? I’m layering with the shape of the gem, which is round.

    3. Keep Layering Brighter Colors

      To keep pushing the contrast up I have to go brighter still. So, I use an a brighter red and layer that over the lower part of the previous layer. This red is Evil Sunz Scarlet.

      Gems 02

    4. Pushing it Even More!

      Now to really push the colors.

      Next I painted an orange, Troll Slayer Orange.

      Gems 03

      Now, depending on the size of the item you’re painting, this could be as far as you need to go. You might find adding more layers is too hard. If so, that’s fine and just skip down to the reflective highlight section.

    5. Orange Highlight

      I like to add a thin line at the very bottom to highlight the orange. For this I used Fire Dragon Bright.

      Gems 04

    6. Final Reflective Highlight

      The final step in this whole process is the easiest and gives the biggest impact; it brings it all home.

      Take a bright color like a very light grey or white (I prefer white), and put a dot at the top of the gem inside that dark base coat. This should be placed where the light source is coming from.

      Gems 05

      That’s it!

    Now, if I zoom out you can better see the effect.

    On a Smaller Scale

    Being that I did that gem very large, you can clearly see the layering, which is what I wanted for the sake of showing you. However, now I’ll show you the same steps on something more typically sized for a 28mm miniature.

    Here’s the base coat, the dark brown of Rhinox Hide.

    Gems 07

    Now for the dark red, Khorne Red.

    Gems 08

    Then the brighter red, Evil Sunz Scarlet.

    Gems 09

    Now I add the orange. The area is so small that I’m really just adding in a very thin line.

    Gems 10

    The brighter orange (Fire Dragon Bright) is almost a dot at the bottom at this scale.

    Gems 11

    Now the reflective dot and done.

    Gems 12

    And zoomed out to better see.

    Smaller example of a painted glass effect

    As you can see, there’s no blending on that smaller gem and it looks pretty good!

    Advanced Glass Effect for Miniatures

    The only thing you need to do to make this an advanced version of the miniature glass effect is to blend those layers that were put down.

    Those layers could have been blended as they were going on but sometimes it’s just easier to blend them after you’ve layered it out. I prefer blending as I go, but it worked out this way for the tutorial!

    Also, to reiterate what I said above, if the scale of what you’re painting is very small, then you may find this is entirely unnecessary. The only time I blend a glass effect is when it’s something larger and more prominent.

    To give an example, something like the lense on a Space Marine’s helmet is not something I blend. It’s such a small area that a few basic layers with a reflective dot does the trick. Same if it were something small like a tiny gem on an amulet.

    However, if you’re painting larger gems, like an Aeldari soul stone on a vehicle, or maybe a crystal orb on a staff, then blending out the layers is useful.

    Start with the Darkest Area

    To start the blending I grabbed my dark red, Khorne Red, and thinned it out to a glaze. I then started the brush in the dark brown area (Rhinox Hide), and pulled down into the Khorne red.

    Gems 14

    As you can see, it’s not very clean. So, I keep doing this to smooth that transition out.

    Gems 15

    I do this a few times to smooth out the transition until I’m happy.

    Now, if you want the blending process explained in more detail, then definitely check out my tutorial on blending. That tutorial covers this in more depth and explains the process of blending more.

    Keep Blending All Layers

    I kept doing the same thing. So, I took the bright red and blended that down from the dark red.

    The Final Result

    Since this tutorial isn’t on how to blend, I’m going to fast forward to the final result, which I achieved by slowly blending each layer and smoothing out those transitions.

    My blending is quick and dirty. I absolutely could have spent way more time working the transitions, however, I’m not one to spend 30 minutes blending out each layer; I’m lazy. I call it tabletop blending.

    And that’s all there is to it!

    Some Examples of My Work

    Just to show you some examples of this effect in practice on miniatures I’ve previously painted, here’s some stuff to check out.

    Abaddon #8

    If you look at the yellow eye in the hilt of the sword you’ll notice the glass effect there. Notice how the reflective spot is towards the top right? That’s because the sword is tilted and that’s where the light would strike, not dead center.

    Chaos Sorcerer in Terminator Armor #3

    The red eye gem on the shoulder I painted with a glass effect. I didn’t go quite as bright in the contrast on this because of how the eye is shaped around the shoulder. Still, I feel the effect came out pretty well here.

    Chaos Land Raider Painted #15

    I know this model is distracting, but if you look at the lenses on the top hatches you’ll see the effect being used.

    Devil Dog

    This Devil Dog was painted by Kamui. I realized I use red a lot for my effect (I love red!), so I wanted to show it done with another color. You can see the lenses on the Devil Dog are a blue-grey.

    Kamui didn’t push the contrast as much as I do but it still looks great and he didn’t do any blending on this either.

    Conclusion of the Miniature Painting Glass Effect

    As you can see, it’s not terribly complicated to pull off this effect. The trick is strong contrast and a nice, bright reflective spot to sell the whole effect.

    It will take some practice, I won’t lie, especially working on smaller areas, but it’s very achievable and you’ll be surprised what you manage in a few minutes of painting.

    There’s a lot more you can do with this effect as well. My tutorial is more or less a tabletop quality example – quick and easy. However, you can play with the reflective highlighting a lot more if you want to push this up a notch.

    Realistically, the reflective highlight would just be a simple white dot at the top. Instead there should be a slightly lighter area in the shape of the gem with a brighter spot in the center of that.

    You could play more with color transitions as well as the shape of the layers. The layers could bow up instead of down. Maybe the layers are completely horizontal instead. There’s really no wrong way to approach this if you follow the basic principles.

    I was really surprised when I first ran across this technique how easy it is to get it to look good. As you say, the smaller scale actually helps it work better, which feels kind of counter-intuitive, but really is the case.

    Your example looks a little odd to me because I almost always assume a light source somewhere off to one side*, rather than directly above, so I’m used to having a bit of tilt to the whole thing. Which is actually one more important point: If whatever you’re working on has multiple gems, be sure to paint them all as tho they’re lit from the same direction. One of the few things that can really screw this up is having gems near each other that look like they’re being lit from different directions for no apparent reason.

    *In my case, I always do it like it’s coming from my left. My strongest light at my painting desk is there, so I tend to use that as my reference when I’m doing highlights, which means it makes sense to do the gems the same. Standardizing it like that also means that they all look like they’re in the same lighting when I have the whole army set up on a display board or something.
