RH28 may just be the logo of the manufacturer. Most jewelry brands are OEM, and PT950 is an authentic platinum logo, so you can't find any information by pressing rHpt950 online. In addition, the necklace engraved with chimelong is also the name of the manufacturer, which has no special significance. There is no requirement that the necklace must be engraved in English. As long as there is the logo of PT950, it is bought in a regular shopping mall and is generally genuine. You really don't trust. You can go to the local quality inspection center for a quality inspection, and the cost will not be too high, just a few tens of dollars. I hope I can help you.

In addition, PT means that the metal is platinum, 950 means that the platinum content is 95%, and the remaining 5% is other metals.
