Magma Shards [Inktober Prompt #10 Pattern]

Introduction:

The Tazalt mountain range that splits the realm of Lahar is teeming with natural resources. Mines litter the mountainside as many work on excavating the treasures of the mountain.
Atop the list for rare and magical finds in the Tazalt Mountains are the ever-burning Magma Shards. The outside of the gemstones is clear as glass with the inside of the gem, an ever-shifting and changing shape. These magnificent little stones always bear a similar look to Magma as the pattern that can be seen under the transparent surface is of flowing magma that seems to keep flowing into itself.
The gems radiate a heat worthy of the high volcano Gol.
