Diablo 3 Radiant Star Gem Crafting Cost Guide

Diablo 3 Radiant Star Gem Crafting Cost Guide

This is some basic math to show how much it costs to craft a Radiant Star Gem and you can manipulate the numbers to show any of the lesser gems as well.

First we need to find the number of lesser gems needed to craft a Radiant Star.

Flawless Square – 729
Perfect Square – 243
Radiant Square – 81
Star – 27
Flawless Star – 9
Perfect Star – 3
Radiant Star – 1

The math on the the above is pretty simple.  Its exponential to the power of 3 as follows = 3^X where X is the number of tiers.

If you want to craft using Flawless Squares you will need 729 of them. If you want to use Perfect Squares you will need 243 and so on.

So here’s the Pure Gold cost you need to pay the jeweler for crafting, assuming you start with Flawless Squares:

Perfect Square: 243 * 30,000 = 7,290,000
Radiant Square: 81 * 50,000 = 4,050,000
Star: 27 * 80,000 = 2,160,000
Flawless Star: 9 * 100,000 = 900,000
Perfect Star: 3* 200,000 = 600,000
Radiant Star: 1 * 400,000 = 400,000

The total gold cost comes to 15,400,000

Now the number of tomes required crafting from Flawless Squares.

Perfect Square – 243 * 3 = 729
Radiant Square -81 * 6 = 486
Star – 27 * 9 = 243
Flawless Star – 9 * 12 = 108
Perfect Star – 3 * 15 = 45
Radiant Star – 1 * 20 = 20

That totals up to 1631 Tome of Secrets.

So the grand total gold cost for a Radiant Star Gem if you’re crafting from Flawless Squares is…

Assuming 200 gold for 1 Flawless Gem
Assuming 500 gold for 1 Tome of Secrets

Grand Total = 16.4 Million Gold
