Let’s breakdown Gem Tiers. There are 9 Gem Tiers in WWE 2K23 and each Gem color determines the range of overall rating a card will be in. This is important for any collector trying to build the best collection of Superstars possible. Any card with an overall rating lower than a 60 will be a Bronze Card, which is the beginning tier of the MyFACTION power curve. Gem types then progress up through Silver, Gold, Sapphire, Ruby, Amethyst, Diamond, and finally the highest Gem Tier Pink Diamond, a 99 overall.
