Information about Legendary Gems in Diablo Immortal, including how to obtain Legendary Gems, how to rank up Legendary Gems, and what their Star Count means.

What Are Legendary Gems¶

There are two types of Gems in Diablo Immortal, Legendary Gems and Normal Gems. Despite their names, you’ll almost certainly obtain a Legendary Gem first, during the main quest objectives “Legends of Eld” and “Braving the Rift” (both of which are part of the game’s Elder Rift tutorial).

Legendary Gems, like legendary-grade equipment, have set modifiers to various stats and skills unique to each specific Legendary Gem; a Lightning Core Legendary Gem will always possess the same modifiers, distinct from a Zod Stone Legendary Gem. In addition to whatever other effects Legendary Gems possess, generally tend to increase your Resonance score (boosts all Attributes) and your Combat Rating, making them essential adornments to your gear regardless of your class or build.

Legendary Gems can be socketed into Primary Gear, including helmets, chest armor, shoulders, legs, and a main hand and off hand. Only one of each type of Legendary Gem can be equipped at a time.

Differences Between 1-Star, 2-Star and 5-Star Legendary Gems¶

Legendary Gems are divided into three categories based on their “Star Count”, which can be found under the gem’s name.

A Legendary Gem’s Star Count is essentially an indicator of its rarity and power, with 1-Star gems being the most common and, at least in terms of purse Resonance and Combat Rating, the least powerful. 2-Star gems are somewhat higher on the hierarchy, and 5-Star gems are some of the rarest and most powerful items in the game.

1-Star and 2-Star gems are both static based on the type of Legendary Gem - a Zod Stone is always a 1-Star Legendary Gem, and a Lightning Core is always a 2-Star Legendary Gem. 5-Star gems can roll up with anywhere between 2 and 5 Stars unlocked. The more Stars unlocked on a potential 5-Star gem, the greater its Resonance and Combat Rating bonuses will be.

How to Get Legendary Gems¶

Regardless of their rarity (Star Count), there are a number of ways of obtaining Legendary Gems, as follows:

• Completing Elder Rifts
• Purchasing them from the Market in Westmarch
• Crafting at a Jeweler

5-Star Legendary Gems are, of course, much, much rarer than their 1-Star and 2-Star counterparts, and while an obscene amount of grinding may get you the gems you want, a common denominator to obtaining 5-Star Legendary Gems is, of course, how much money you’re willing to spend.

Getting Legendary Gems from Elder Rifts¶

You can open Elder Rifts by using rare and or legendary crests, the latter of which will increase your odds of getting better Legendary Gems when you complete said Elder Rift. You can, of course, buy Legendary Crests from the Crest Merchant in Westmarch using premium currency. You will obtain Runes as a consolation prize for completing Elder Rifts, which are another way to potentially obtain Legendary Gems.

Getting Legendary Gems from the Market¶

Diablo 3’s “Real Money Auction House” was a roaring success that everybody loved, so it’s no surprise a version of it has popped up in Diablo Immortal via the Market in Westmarch. Here you can find gear being sold - for premium currency - potentially including 5-Star Legendary Gems. Keep in mind that only Legendary Gems found in Elder Rifts opened by Eternal Legendary Crests can be sold on the Market, meaning only Legendary Gems obtained by spending premium currency at the Crest Merchant can in turn be sold.

Crafting Legendary Gems¶

Visit a Jeweler and pick the “Craft” option and you’ll find various formula for creating Legendary Gems. All of these formula require Runes (and some also require premium currency); different Runes are required to craft different Legendary Gems. Specific 1-Star and 2-Star gems can be directly crafted, but if you want a shot at up to 5-Star gems you’ll need to “Random Legendary Gem” formula.

How to Upgrade Legendary Gems¶

You can upgrade Legendary Gems (increase their rank) by cannibalizing other Legendary Gems, which will provide an amount of Gem Power based on the consumed Legendary Gem’s Star Count. The exact type of Legendary Gem consumed doesn’t matter during early rank ups, and any excess Gem Power will be stored as Gem Fragments (one Gem Fragment = one Gem Power). The higher a Legendary Gem’s rank and Star Count, the more Gem Power it’ll take, and more and earlier it’ll start requiring duplicate Legendary Gems to craft. I.e., a Lightning Core Legendary Gem will require the sacrifice of another Lightning Core Legendary Gem to upgrade. Since you can’t equip multiple copies of the same type of Legendary Gem, this is less painful than it may otherwise sound.
