Here we have a beautiful set with 31 selected specimens from Bulgaria including Rhodochrosite, Quartz, Pyrite, fluorescent Calcite, Galena, Chalcopyrite, Amethyst, Sphalerite, Stilbite. Size of the box is 40 x 27 cm. Size of the specimens is from 2,7 x 2,5 x 1,8 cm to 13,0 x 10,0 x 4,5 cm. This specimen comes from a reputable source and has not been altered or treated in any way—what you see is its natural form. The photos are taken under daylight-equivalent LED lighting to show the specimen as accurately as possible. Please note: some colors can be difficult to capture accurately in photographs. I do my best to present the specimen faithfully. All items are professionally packed and shipped with tracking. I have many years of experience in international mineral sales and strive to provide accurate descriptions and high-quality service. Feel free to reach out with any questions—I'm happy to help.
