Okay guys, so this is the gem display rack from some time ago. These gems were found by a mermaid, under water I think. I don't remember anymore, but the shot is from a mermaid's house, I know that atleast.

A long time ago, after playing this, I found a book-case display rack that I've since use manyyyyy times, because it can fit three gems in each shelf, and I hate these stupid EA display racks that take up so much space and only displays like four or five gems as opposed to like, twenty or thirty.
It wasn't until I spotted this screenshot that I realized my gems aren't so big anymore.
This is was my gems look like now, and have for a super long time.

I don't use any gem-shrinking mods that I know of. I only use a couple of nraas mods that are unrelated - and this book case. Cant remember where I got it but I think it was a sort of "empty bookcase" form Modthesims. Anyway, how big are gems suppose to be? Are they bigger if collected by an occult/special sim?? I have no idea what to make of this. I really miss having big gems - but I also want a super way of display them.
edit: it was this bookcase

IP is the most recent EP I've bought. But I still haven't played that world yet. Didn't know about the treasure chests.
I have it too, everyone says it's the most glitchy world, played it a bit, wasn't blown away....

No cheat needed, just put enough gems in the more expensive showcase (Carters Display Case) and 'transmogrify' the contents. This is done in game (Life Mode). The result depends on gem type, gem cut etcetera. You can also mix things up to get a whole bunch of surprises! Apart from gems, you can play with metals, artefacts and combinations. Some changes can be quite profitable, while others cost (much) more than you get back. The fun is in finding the right 'recipes'. The simplest: 10 gems of the same type and cut => 1 large of that type and cut.

The easy way is to send a Sim scuba diving and if he's lucky there'll be some large gems in treasure chests.
The other way is to get the Carters Display Case from World Adventures and put 10 of the same gem on it and choose the Transfigure option. Then I get 1 large gem.

I just built a scuba diving lot and placed some chests.. hopefully the chests "respawn" once opened, right? I can't remember if they did or not last time I played.

If I remember correctly, the chests are a one-time thing for each Sim. A different Sim can open them again and get the same treasure. They don't seem to work the way the treasure chests did in World Adventures.
You can also nab gems in vacation worlds. Make sure your Sim has a Collection Helper to find them. Pretty much all my Sims end up with a lot of gems, mostly collected but a number of them from the consignment store too.

Also, if you are using the carter display case for metal, you can have an alien transmute it a bunch first, I've had large compendium ingots worth over a million simoleans, its kind of silly really.
Then if you have a Sim with high Martial Arts skill they will be able to break Space Rocks.
Space Rocks give gems when broken.
If your Sim happens to have the Disciplined trait they will break space rocks all day and all night if they can get away with it and you'll have more gems than you can cope with.
You will eventually probably want to remove that particular trait as there are just so many gems you can cope with in a single household.
It is a good idea to put the board breaker in a big room to leave space for all those gems to go.

Using the collection helper in any world and just picking up all the uncut gems is the fastest way to accumulate many of them. The EP specific ones might require traveling though.
Transfiguring normal gems to large ones only takes 8 gems if you use the large Carter's Display Case. The smaller case holds 10; I'm not sure if 10 is required on the smaller one to activate transfiguration. I always use the larger case because it (oddly) holds less.
Second easiest way IMO, is training a dog to hunt.
Breaking space rocks is nice, but unlike the first two methods it spawns them all over the ground and your sim still has to run around collecting them all.
Someone posted a screenshot of a large skull shaped tiberium a while back, now THAT sounds like a challenge to get, I wonder if its worth more than a large spire cut, and if you leave it out if it will change to spire cut, almost curious enough to go check, almost.
ETA: Another thing to consider if your sim has science, is you can just clone gems, for free, and quite fast, if you do it for tiberium and have a gemcutter, make sure to clone the raw form though, as the cut gem AND the gem dust will grow to large spire cut after a few days.

Thanks for the link. I had a quick look earlier and couldn't find it and got a bit frustrated.
I will see if I can make a skull cut tiberium but it may take a while. I do have a lot of cut gems though so will have a look through my chests and see what I can find.
If you have the gem cutting machine and cut the tiberium there you end up with your cut stone plus gem dust and that gem dust will turn into spire cut if you leave it out.

Level 8 or 9 of the science skill from University allows your sim to clone items they have analyzed and obtained a sample of. Works for gems, metals, rocks, insects, harvestables, and sims.
