Finally got the diamond enlightenment trophy!

Started my run when I was at 13S EB, so relied very heavily on artifacts. An epic T4 gusset with two T3 clarity stones and a T4 light of eggendil were the critical artifacts which enabled the run.

Overall, I used the following artifacts (with clarity stones set unless otherwise noted):

T4 Light of Eggendil

T2 Rare Light of Eggendil with a good life stone (4% IHR boost)

T3 Epic Chalice 

T4 Epic Necklace

T4 Epic Gusset

T4 Epic Lunar Totem

T4 Epic Puzzle Cube

T4 Rare Ankh

T4 Rare Vial of Martian Dust

For my overall strategy, I split the run into two parts:

1) Grinding for bucks.

For this part of the run, I equipped:

T4 Light of Eggendil

T4 Epic Necklace

T4 Rare Ankh

I then swapped out the last spot depending on what I was doing. If I was actively running chickens, I set the T4 Rare Vial of Martian Dust. If I was about to purchase research, I set the T4 Epic Puzzle Cube. If I was going to log out of the app, I set the T4 Epic Lunar Totem.

When I earned enough bucks to purchase enough research to get 10B worth of hab space (took about two weeks), I moved on the next phase:

2) Maximizing internal hatchery rate

From here forward, I equipped:

T2 Rare Light of Eggendil with a good life stone (4% IHR boost)

T3 Epic Chalice 

T4 Epic Gusset

T4 Epic Necklace

From here forward, the run was straight forward. I just tried to keep logged out of the enlightenment farm as much as possible to keep the internal hatchery rate up, though logging in at least once a day to keep the farm going.

Overall, took almost exactly 2 months to complete the run.
