To solve this, I would write a proportion, it makes everything easier.
Since we don't know what the original value is, it will be x. The second proportion is the percents of everything.
455 130
x 100
Cross multiply 455 by 100 and then divide it by 130.
This gives you 350.
The original Price of the necklace is 350
Comment if you have any Questions,
Hope this helps <3
