Details: 
-gold gemstone with many more loops for adjustability as shown at 12.25 on the measurement pic  
-the multiple necklace strands have been intentionally twisted for the design effect
Error: 
-gold Dior logo circle tag has a literal ‘ \’ mark on the right of the ‘R’ on the ‘DIOR’ logo part; also a slightest scrape on the left of the ‘D’ of the ‘DIOR’ logo part as well
-back of the Dior logo circle tag has a mark going across it; again emphasis on the fact that the necklace itself is perfectly fine and features no other noticed flaws
