Rare 700ct (140g) Natural Burmese (Mogok) Ruby Specimen

LAST LARGE FULLY TURMINATED 700ct BURMA RUBY CRYSTAL YOU WILL EVER SEE FOUND BY MY PAST FAMILY GENERATIONS AGO.

Provenance & History

  • Origin: Mogok Valley, Burma (Myanmar)
  • History: Passed down directly through family provenance, originally acquired prior to 1960 when the owner emigrated to the United Kingdom.
  • Significance: Old-collection Mogok specimens of this size and era are increasingly scarce, having been sourced during the classic mid-20th-century period of Burmese mining.

Gemological Description

  • Weight: 700 Carats / 140 Grams
  • Dimensions / Scale: Substantial hand-sized piece (approx. 140 g)
  • Color: Deep, vivid purplish-pink to raspberry-magenta with strong natural saturation typical of marble-hosted Mogok corundum.
  • Structure & Mineralogy: A massive, fully terminated natural ruby crystal.

Potential & Uses

  • High-End Mineral Specimen: An impressive, historical display piece for serious mineral collectors or museum-style collections due to its size, historic pre-1960 provenance, and classic Mogok origin.
  • Lapidary & Carving Material: Exceptional raw material for high-end artisan
  • My late father gave me this on my 16th birthday in 1985
