Hi, the number of enchanted gems is proportional to the number of (unspent) blue gems you have when ascending. If you had 7 blue gems, you will get 7 Enchanted Gems. It seems unlikely that you would only get 7 gems in your entire run, but if that really was the case, note that your first ascension will likely give a lot of gems as there is a 100% gem drop chance the first time you kill a boss (aka beat your highest zone), after which it is a base of 30%. You may want to get the Lucky Charm if you haven't already to also reduce the dependence on randomness or luck to get gem drops as it boosts your chances to get gems from the subsequent boss if a previous boss failed to drop them.
