Gem Perfection is a passive trait exclusive to Jewelcrafters. It gives a chance when cutting uncommon Northrend gems to cut it into a "perfect" gem, slightly raising its stats (by 15% or more).

Source Edit

Once you reached Level 50, you will be eligible for the starting quest offered by any of the Northrend starting area trainers (These quests seem not to require a certain Jewelcrafting skill):

Notes Edit

The exact proc rate for this skill is still unknown because of insufficient data. However, initial findings estimate the proc rate to be 10-20%.

For example, one crafter found a 20.45% perfect cut rate out of a random sample of 200 gems.^[1] This crafter later made a table showing results for over 650 gems and found an overall rate of 20.22%, but varying rates depending on the type (Bloodstone, Delicate, 49 cut – 18.33%; Chalcedony, Solid, 57 cut – 28.75%; Dark Jade, Jagged, 139 cut – 20.11%; Huge Citrine, Luminous, 64 cut – 20.00%; Shadow Crystal, Purified, 136 cut – 17.07%; Sun Crystal, Smooth, 64 cut – 20.00%).^[2]
