【From the official website】 The diamonds, arranged without gaps, shine off each other, creating breathtaking beauty. This stud-type necklace is easy to match with any fashion. The beautiful chain, which doesn't lose to the gorgeousness of the motif, comes with an adjuster. You can adjust the length to match the neckline of your outfit (max 45cm). It seems that the square necklace with the same 0.4ct diamond is not currently sold (this was purchased in 2022). Currently, you can order either 0.2ct or 0.5ct, but for reference, I have attached official photos in the 5th and 6th photos. Please check the actual images from the 1st to 4th photos. I have worn it a few times since I bought it. The diamonds are so beautiful and cute, but it no longer matches my fashion, so I am selling it! The price seems to have gone up now, so I think this is a good deal. I will include the case and the appraisal certificate. Material: K18 (18k gold) Decoration: 0.4ct Diamond
