Q. Assertion :Diamonds are known for their spectacular brilliance, but diamonds found in nature rarely exhibit the brilliance
Reason: By cutting the diamond suitably, multiple total internal reflections can be made to occur.

Ray Optics and Optical Instruments

Solution:

The critical angle for diamond-air interface is very small, therefore once light enters a diamond, it is very likely to undergo total internal reflection inside it. It is the technical skill of a diamond cutter which makes diamonds to sparkle so brilliantly.
