Liquid Diamonds is neither good nor bad in isolation (no pun intended).

THC-A crystal gets melted into THC oil then mixed with terps.

That is arguably like buying fruit juice from concentrate or parboiled rice. Neither particularly good nor particularly bad, just that cannabis marketing managed to invent a way to grift nuStoners by selling a simple processing step as a bespoke product.

Now.

There's one POTENTIAL advantage, namely that you CAN use this as a means of keeping use of liquidizers down/eliminate it entirely and keep natural terpenes intact.

It (IIRC) also heavily stabilizes cart oil so it resists mechanical and temperature shocks better but I don't fully know that

On the other hand, this can also be used to assemble cart oil from completely random compounds by giving you a pure THC base (often derived from conversion of CBD in grey market labs to sidestep taxation) to mix a laundry list of foreign substances into.

TL;DR:

-It can be good

-It can be neutral

-It can potentially be really bad

It simply describes the act of decarbing THC-A crystal into THC oil in separation of other cannabis compounds to add them together again later. Why that is done and what is added is the real question.

I hope that made sense.

PS: One potential major disadvantage is that only THC absolutely obliterates your tolerance and then you'll be in a world of hurt. Think of all the things people use THC for (quasi)medicinally. Like with all forms of withdrawal you'll experience some degree of those conditions once you've done that.
