(^^) Feel free to comment! (^^) ☆ I've unearthed this. This isn't just any rhodochrosite. This is a genuine, unheated rhodochrosite from the past, the kind that's said to "retain its value across generations." ☆ ① High transparency. ② Strong, orange-leaning color. ③ The extraordinary jump in saturation and neon-like luminescence when exposed to light (please see the video). ④ Appraisal certificate from the National Gemmological Association. ☆ Because this piece has all of the above ①-④, it's highly likely to be from the Sweet Home Mine in Colorado, USA. It's significantly more valuable than those mined recently. ☆ The Sweet Home Mine completely closed in 2004, and there's virtually no chance of it reopening due to geological conditions, mining costs, and environmental concerns. Therefore, the current stock on the market is the total global supply. You'll see many pieces claiming to be Sweet Home Mine rhodochrosite that lean towards pink, but they're completely different when compared. ☆ While many gemstones maintain their supply even when the source changes, there's no other source that can match the quality of Sweet Home Mine rhodochrosite. Many you see on the market are the type mixed with calcite, and unfortunately, they don't exhibit the neon-like luminescence of this piece. ☆ Currently, the value of Sweet Home Mine = premium is established, mainly in the European and American markets. Professional collectors who can judge by photos and videos actively seek these out, even without the origin stated on the appraisal certificate. ☆ Please, take it and cherish it!
