Among Diablo Immortal's plethora of upgrades, currencies Diablo IV Gold, and reward strategies, legendary gems is the ones where the business model is at its the most. Blizzard and NetEase haven't been so outrageous as to offer them directly through a loot bag or gacha feature but what they have developed is, to put it in perspective, even more troubling. Legendary gems only drop from the bosses in the randomly-generated Elder Rift dungeons, and you can only guarantee the legendary gem's drop by applying a legendary crest modification to the dungeon prior to starting the dungeon. In other words, the rates of drop for gems with legendary status are extremely low.
Without spending any money on the game, you'll only collect one legendary crest every month. Even purchasing an account for battle will only reward you with one or two additional legendary crests per month. Beyond that, you'll have to buy them directly. Legendary crests are priced around $2 to $3 for each. The huge number of gems you will need to make the most of your character's equipment particularly in light of the low drop rates for five-star gems, is one of the reason why the cost of maxing out your character's capabilities within Diablo Immortal has been estimated at approximately $50,000-$100,000 -- potentially even more, in the event that you go deep into the gem resonance system. (Rock Paper Shotgun comes with a very thorough cost breakdown that puts it on the moderate end of the scale.)
Diablo Immortal has been given an extremely rough ride due to the business model it is based on -- perhaps disproportionately when you consider that other popular free-to play games like Genshin Impact and Lost Ark are not without similar gacha mechanics that entice huge-spending "whale" gamers. Diablo's fame and reputation with its core PC gaming audience, built over the course of a quarter century, is certainly one of the reasons. However buy Diablo 4 Gold, it's also true Diablo's gaming system is particularly challenging and the very nature of Diablo games could have an impact on that.
