About Blue Sapphire as a Gemstone
Sapphire is the gem variety of corundum, an aluminium oxide crystallising in the trigonal system. Blue is the colour most people picture, but corundum occurs in nearly every hue, including pink, yellow, green and violet. Only red corundum takes a separate name, ruby. Trace iron, titanium and chromium drive the colour. You can read more via gemmological reference, mineral data.
Corundum forms in aluminium-rich, silica-poor settings, typically metamorphosed limestones and marbles or alkali basalts that carry crystals upward from depth. Because corundum resists weathering so well, many working deposits are alluvial, with crystals recovered from river gravels far from their original host rock.

Frequently Asked Questions
What are the exact measurements of this Blue Sapphire?
This stone measures 10.7 x 6.4 x 4.2 mm and weighs 2.5 carats. Those figures are taken from the stone itself, not estimated from a category average.
Is this hardness suitable for daily ring wear?
Corundum ranks ninth on the Mohs scale, making it one of the toughest coloured gemstones available for jewellery. It withstands daily friction from clothing and regular wear without losing its polish.
How does the pear cut behave in settings?
The pointed tip requires a V-shaped protective prong to prevent chipping during mounting or accidental impacts. Your setter should take care to secure this corner properly before final delivery.
How should this stone be cleaned safely?
Warm soapy water and a soft bristle brush will remove everyday skin oils and dust safely. Avoid harsh chemical dips that might damage surrounding metals or composite settings.
Does the colour shift in different light?
Blue sapphire generally maintains its body colour under both daylight and indoor tungsten lighting. The facet arrangement helps bounce light internally to prevent dark extinction windows.
Will I receive the exact stone shown in the photos and video?
Yes. Each listing covers one individual stone, and the media on this page was shot from that stone. Once it sells, the listing comes down.
