Michael Kors ring sz8 + fashion jewelry bracelet & necklace

I feel like it is closer to 7 but you can see it is stamped with an 8 I’m honestly not sure what the metal is - another post says white gold plated but I can say for certain is does not turn your finger green Not real diamonds - a few crystals are missing (I tried to show in picture) Also comes with a bonus bracelet & necklace - no real diamonds - a jeweler said the pearl is real though but I do not have documentation of it
