In Diablo 4, Crude Sapphire belongs to the lowest category of gems in the Sapphire family. It can be put into different kinds of equipment for which it adds various buffs. This guide will take you through what Crude Sapphire does to your character, ways to improve it and where it is supposed to be placed.

Effects of Crude Sapphire

Depending on the type of equipment into which Crude Sapphire is socketed, it provides the following benefits:

Weapons: +[6-1%] Critical Strike Damage to Crowd Controlled Enemies

When inserted into a weapon, Crude Sapphire raises the critical strike damage that crowd controlled enemies suffer. The bonus greatly increases your offensive power as more harm shall be caused to controlled foes.

Armor: [4-1%] Damage Reduction while Fortified

Armor with a slot for a gem like this has a damage reduction capability during fortification. This decreases incoming damage and thus makes you more likely to survive combat situations better.

Jewelry: [11.5-1%] Cold Resistance

If placed in jewelry such as rings and amulets, Crude Sapphire offers cold resistance. By reducing the amount of cold damage taken from enemies, it increases your chance against cold-based attacks.

Upgrading Crude Sapphire

Crude Sapphire can be upgraded to a higher tier in order to make its benefits stronger. Upgrading involves three gems of one kind plus some gold coins. By upgrading gems, they offer stronger advantages when inserted in gear.

Crude Sapphire being at its base level can still be improved up one level more; Chipped Sapphire which brings about extra rewards on top of increasing the general strength of the gemstone.

Inserting Crude Sapphire

You can insert crude sapphire into any empty socket on your equipped gears. This means that when it comes to weapons, armour or jewellery you will have an option where you want them attached so that you get to enjoy their buffs. In addition, the jeweler can get gems unsocketed without destroying them for your reuse in different gear combination since he is an important NPC.

Apart from upgrading armor and weapons at the Blacksmith's, you can also have your rings and amulets' resistances or additional stats improved by the Jeweler.

When looking for a spot to socket your Crude Sapphire gem, you need to bear in mind your build, play style as well as the specific attributes that you want to improve. Experiment with different combinations and find out which setup suits your character best as it improves how effective you are in combat.
