[Lottery Sale 0731_01] Unheated Yellow Star Sapphire from Myanmar 1.004ct Loose Stone with Japan-Germany Gemological Report
Click here to apply for the lottery sale.
Sapphire is a famous gemstone that needs no introduction. Although the mineral is corundum, just like ruby, all corundum that is not red is called sapphire, so there are also yellow ones like this. Among these, this one exhibits a star effect, and a penlight was used for shooting. The back of the stone is basically unpolished.
This is a Yellow Star Sapphire from Myanmar that fully displays its star. An identification report is included.

※ If you would like an image photo of the stone on a setting, want to consult about full custom orders, or have any other questions, please feel free to contact us here.
※ Raw stones are not supported. Also, some stones may not be supported.
※ We strive to ensure that the photos have the same color as the actual product, but due to the lighting conditions during shooting, your monitor environment, etc., the actual product may look slightly different. Also, some photos may have been taken using a penlight.
※ For products with UV fluorescence photos, a 365nm wavelength black light is used for shooting. If you use a light with a different wavelength (e.g., around 395nm), the fluorescence may appear weak or difficult to confirm. The black light we use is here.
