how much robux is 500 gems in 99 nights

July 7, 2026

I couldn’t verify a 500-gem to Robux conversion for 99 Nights from a direct in-game source, but the public pricing I found shows 100 Diamonds = 400 Robux and 250 Diamonds = 900 Robux. That implies 500 gems would be about 1,800 Robux if the game’s gem-to-diamond pricing is linear.

Quick Scoop

100 Diamonds cost 400 Robux.

250 Diamonds cost 900 Robux.

500 Gems is roughly double 250, so the nearest estimate is 1,800 Robux.

Note

This is an estimate based on the published diamond bundles, not a confirmed standalone 500-gem pack. If the game uses a different item name or a separate shop, the exact price could differ.
