Whilst rubies from Burma are justifiably revered around the world, their sibling sapphires were, for many years, somewhat overlooked. The Victorian London jeweller Edwin Streeter described them as being overly dark and, despite this not being the case, his opinion was repeated by others and seemed to stick. It took decades to reverse this but today Burmese sapphires are recognised for the wonderful gems they are, indeed many view them as surpassed only by sapphires from Kashmir. Burmese sapphires are found predominantly in alluvial deposits in the Mogok area in close proximity to rubies. Whilst rubies account for the majority of the gem output, sapphires forming only 10-20%, it is the sapphires that occur in larger sizes with rough weighing 40/50/60/cts not uncommon. Burma is also now known for producing excellent star sapphires, these rare gems appear to have a bright six rayed star floating just under the surface and are very beautiful. The best Burmese sapphires, like this one here, possess a rich, desirable intense blue with excellent saturation however they also occur in lighter shades as well as in purple, yellow and green.
