A century -old diamond ring, two barcodes engraved in the inside of the ring, I don't understand. On the one hand is "AU750 Fate", and on the other is "D0.054ct". What does it mean? How much does this ring market price? Trouble understand, thank you.
The AU750 is the gold content that indicates that this material is a gold alloy with a gold content of 75%, which is G18K.
As for the word "fate" after the AU750, the factory label of the century fate
d0.054ct is to indicate the weight of the diamond on this diamond ring 0.054 carats (or 5.4 points)
How much and how the craftsmanship can be for your valuation.
The market is generally around 2000. If it is a brand, it may be slightly more expensive.
The cost mainly depends on gold weight and process costs. Generally, it should be within 1,000 or about 1,000.
