Opalescence

Opalescence is a simple mod that adds Opal, a new stone type that changes hue depending on its location in the world.

Features

Opal generates naturally in the underground. It can be uncommonly found in the deepslate layer below Y=0, or more rarely in the stone layer between Y=32 and Y=56. Some of the naturally generated stone will bear crystals, which can be crafted into regular opal blocks, allowing for a renewable source of opal.

Letting the moon shine on fully grown, but still attached to the budding block crystals lets them aqquire a new, pearlescent hue (doesn't work when moonlight is weak). These moonlit crystals can be crafted into their respective opal variant.

---

Both regular and moonlit opal can be crafted into various different shapes. Just plop down the stone into a stonecutter (or smelt it) and choose whichever variant you like best :)

---

You can also make some "interesting" hues by placing a full composter under the budding opal block and letting it influence the grown crystals. Why would you do that though?
