I purchased this from Estell a few years ago. The chain has a slight kink in one place, but it doesn't affect wear. Length: Approximately 43cm Main stone: 0.34ct. There is no appraisal certificate, but I can confirm inclusions with a loupe. I decided to purchase it because the inclusions enhance the reflected light. It sparkles beautifully when worn. It weighs 4g and is well-made. I loved this piece when I bought it, but I haven't worn it much, so I'm selling it. I hope it goes to someone who will cherish it. Suitable for the office too. I have disposed of the original accessories, so I will pack it carefully to prevent damage during shipping. There are no noticeable scratches, but there may be minor scratches from use. Please refrain from purchasing if you are overly concerned about this. I am also selling this on other sites, so please forgive me if it sells out. Thank you for your consideration.
