In this product, crystals that fluoresce when exposed to ultraviolet rays form fluorite clusters that bloom profusely on the host rock. *Fluorescence (blue) is the second image. *There are individual differences in color tone, transparency, degree of fluorescence, etc. depending on the product. Also, because it is a natural mineral, there may be turbidity, dirt, scratches, cracks, discoloration, inclusions, mining marks, etc. (see image).

[About fluorescence] This product was photographed using a Sankyo Electric Blacklight fluorescent lamp stand (near UV-A/Long-Wave/365nm). Although there are slight differences in the degree of fluorescence (color, location, etc.), it fluoresces around 365-395nm (UV-A/Long-Wave). *UV-A black light, which has less visible light, causes the irradiated target to emit more vivid fluorescence. Fluorescence can also be made more noticeable by darkening the room and making the background black. *There are individual differences in the level of fluorescence, and it also depends on the performance of the black light you are using. *This product does not include a black light, so you will need to prepare it separately. *Special case, storage box, manual, label, black light, etc. are not included (this is an eco-package to protect against damage). *There are individual differences depending on the product. Also, because it is a natural mineral, there may be turbidity, dirt, scratches, cracks, discoloration, inclusions, mining marks, etc. *No jewelry processing is applied.

[About product images] There may be slight differences in color tone, etc. due to differences in the shooting environment (light intensity, color temperature, etc.), the customer's confirmation environment, and differences in the computer environment. Also, since the photos are taken in a brighter environment than usual, the color tones and play-of-color effects may appear more vivid. Especially when photographing play-of-color effects, we also adjust the angle of the light. Some minerals, such as fluorescent minerals and fine minerals, are photographed using special environments and equipment.

Also, because it is a natural material, there may be cloudiness, scratches, cracks, inclusions, etc. Since the quality of products created by nature is not constant, we carefully select products with a certain range of quality that match the products we sell, but there may be cases where the human standards for determining quality do not match the customer's standards.
