Birthstones

Thanks for the idea and the overview. I don't celebrate my sims' birthday except from when they need to make that cake to grow into next life stage, so I would not have a clue regarding seasons. But, if going for birth stones, I'd just set a date and try to vary a bit. In my on the side notes spreadsheet I always note what season they were born into.

However, I scripted some calculations in my sims' online bio pages, resulting in a couple favorite crystals for most sims. Then I can quickly check what is their favorite, unfortunately it is often some very rare crystal which is hard to get without cheating, but that just adds to the quest - will they get their fave gem jewelry before they hit the coffin?

I do not recall all details re those calculations, but I probably included favorite color, traits, aristocracy or not, maybe even skills and reputation etc.  I also have my additional DNA string in my game, telling me how a sim feel about traditions/modern, bling/natural and more, all relevant for this kind of calculations. The idea was that some personality might favor darker or lighter gems, the playful sim might want something less traditional, the wealthy want something exclusive and rare, and so on. In the end the script picks their top 3 gems as their possible favorites. A few sims score too poorly to get a favorite at all :)

I agree that crystal creations pack would have had a better impact on the game if it was released earlier. It's become a favorite pack for sure, but so many more products could be crafted, like medals, brooches and tiaras! And, although the designs on offer looks great, I always missed a few more plain alternatives, like a ring and earrings which are basically just the crystal and not so much design.
