where $\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}{\text{b}}_{t}$ is the nominal magnitude of the bonuses granted by Grand Spectrum jewels of that type, $\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}{\text{n}}_{t}$ is the number of socketed Grand Spectrum jewels of that type, and $\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}g$ is the total number of socketed Grand Spectrum jewels.

Example

Say the player has 1× and 2×. This would result in:

No results * 1 * 3 = + to maximum Mana

No results * 2 * 3 = + to Armour

Maximum Values

If you equip all three Grand Spectrum of any type, you can use the following table, simply select the number of Grand Spectrum of the given type you intend to equip, and add the results:

Item	1st	2nd	3rd
Crimson Jewel	600 Armour	1200 Armour	1800 Armour
Cobalt Jewel	90 Mana	180 Mana	270 Mana
Viridian Jewel	36% Elemental Damage	72% Elemental Damage	108% Elemental Damage

Jewel limit

The jewel limit is shared across all 'Grand Spectrum' jewels. For example, if a character has 3 Cobalt Grand Spectrum jewels socketed in their passive tree, they cannot use any Viridian or Crimson Grand Spectrum jewels.
