First of all, we are all up way too late and our parent''s are gonna be really p......sed! Back to the topic; diamonds face up best under natural lightiing. If you are viewing a diamond under spot/track lightiing, do not make a judgement as to it''s cut quality! These types of lighting will make a poorly cut gem give off a false, unnatural sparkle. You must view the diamond in an environment that simulates natural sunlight.( a combination of incandescent and flourescent) Do not be deceived by hot showroom track lighting!
