Tanzania's Winza and Longido deposits produce rubies of exceptional quality — rich, saturated reds with natural fluorescence that rivals the finest Burmese stones. The Winza discovery in 2007 sent shockwaves through the global gem industry. Jonathan's proximity to the Tanzanian mining network gives Luminara Gems access to stones with full government documentation.
Every stone is individually verified by Jonathan Ghikas — licensed wildlife conservationist with direct access to Tanzania's licensed Arusha gem trade networks. Government Certificates of Origin from the Tanzania Mining Commission included with every purchase. Optional Sanaa Chains blockchain tokenization available.
