What makes color-change diaspore different?
Its appearance changes with the light source. Our brochure shows kiwi-green tones in daylight and pink to red tones under incandescent light. The exact effect varies from stone to stone.
Will every stone look like these photographs?
No two stones are identical. Cut, size, clarity and lighting influence the appearance. The brochure photographs show examples; the opening and source illustrations are AI-generated. Ask for photos and video of the actual stones you are considering.
Where do your stones come from?
Our natural color-change diaspore is extracted from our own bauxite quarries in Muğla, Türkiye. The rough is selected and sent to expert cutters before the finished stones are offered directly.
Can I request a laboratory report?
Laboratory reports are available on request. Contact our team to discuss the report and arrangements for the particular stone you are considering. The downloadable product brochure is not a gemological certificate.
How do I find available cuts, sizes and prices?
Request the current stone list. Tell us your preferred size and shape, color-change strength, quantity, budget and delivery destination. We will discuss the available options and relevant details with you.
