＊Please note that the play-of-color seen in the photos may vary depending on the device, light source (natural light, LED, fluorescent light), and viewing angle. ＊This is a precious opal with a dark blue base and blue and green play-of-color. The neon green is very vivid. ＊The setting is simple and can be worn daily regardless of age. The diamonds are also of good grade. ＊Opal is produced in thin layers sandwiched between the host rock, so stones with a significant thickness that do not contain the host rock are valuable, and the play-of-color becomes more diverse. There are many color-related proper nouns, and there are many collectors, but the production volume is decreasing year by year. ＊The item for sale has a small amount of white host rock remaining on the back. This amount of host rock would not be classified as a boulder, and it also serves as proof of the natural stone, but please refrain from purchasing if you are concerned. ☆The Venetian chain is a standard size with a strong presence that can be used on its own. It can also be used with your existing pendants. ＊Opal is the birthstone for October Stone for Libra and Scorpio 6th-anniversary stone. ＊Pendant ・Metal type: Pt900 ・Black Opal: 1.27ct ・Diamonds: 0.18ct ・Size: Approximately 19 x 8mm ・Weight: Approximately 1.881g ＊Venetian Chain ・Metal type: Pt850 ・Size: 0.8mm ・Length: 45cm slide ・Weight: Approximately 2.996g ＊Accessories: Necklace case ＊Creating a product identification certificate is a paid option.
