"1054 AR" stamped on a gold necklace typically refers to the manufacturer's mark, identifying the jewelry maker or company that produced the necklace. It does not indicate the gold's purity or value, as those would typically be expressed in terms of karats (e.g., 14k, 18k).
18k gold
The 0750 means the watch is 18K Gold>
it means gold plated
This means that the ring is matt gold electroplated. The 18k is the amount of gold that is found in the ring.
Bvlgari 18k silver necklace
I had the same thing stamped on my 10k gold necklace. I called a jeweller and they weren't very helpful but they told me it was most likely the brand name.
"18K" should be stamped on the inside of a ring band or near the clasp of a bracelet or necklace if it is 18 karat gold. No stamp may mean it is custume jewelry or the stamp may be worn off. A jeweler can authenticate a piece for you if you are unsure.
The ring is not actual solid 18K gold, it is only plated with 18K. The metal under the plating is not gold!
in all probably hct is a company ident .mark if hge (heavy gold electroplate) ge (gold electroplate) gf (gold filled) P (means plum gold or exactly 18k,14k,12k,10k,9k,)
"18k" refers to the purity of the gold, in this case 18 karats. "ch" may indicate the chain style such as cable, curb, or hollow rope. This means the necklace is made of 75% pure gold and may have a specific type of chain.
its only 18k gold plated, not full gold This could be incorrect. If the ring has 18K/PLAT then the ring is 18K gold with some platinum. Probably to hold the diamond.
