“The Fluorescent Brick” Specs: ⚖️ Weight: 1.25 carats 📐 Dimensions: 8.2 x 4.2 x 3.67 mm 🌍 Origin: Tanzania (Mahenge/Ipanko region) 💎 Cut: Baguette Step-Cut 🎨 Color: Deep Grape / Plum Purple (dark tone, shifts with lighting) 🔬 Clarity: Eye-clean to lightly included (some silk typical to locale) ⚠️ Treatment: None / No Heat (indicated by strong natural fluorescence) The UV “Glow” Test: Swipe to see the third pic—under long-wave UV this stone blazes with intense orange-red fluorescence (chromium content). This is the signature of natural Tanzanian spinel and a quick way to confirm it’s not synthetic or glass. Keep this in mind for your custom setting!
