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 9.2 x 8.1 x 4.1 mm and weighs 2.75 carats. Those figures are taken from the stone itself, not estimated from a category average.
What type of setting works best for this stone?
Because of the high durability of corundum, your jeweller can use standard prong, channel, or bezel settings with confidence. A secure bezel will protect the girdle while highlighting the clean lines of the oval cut.
Is this stone suitable for a daily wear ring?
Yes, corundum is second only to diamond in hardness, meaning it resists everyday scratching very well. It is robust enough for regular use in a ring or bracelet setting.
How does the colour behave in different lighting?
The rich blue tone remains deep and distinct across various lighting conditions. It absorbs light efficiently to show strong saturation without losing its dark character.
How do I clean this sapphire safely at home?
Use warm soapy water and a soft brush to remove everyday oils and dust from the pavilion facets. Rinse thoroughly with clean water and dry with a lint-free cloth.
How long does delivery take, and can I return it?
We contact you directly as soon as your order is placed to arrange delivery, so you always know where the parcel is. Returns are accepted within 7 days of the date you receive the item.
Are your stones natural, or are any of them synthetic?
Everything we sell is 100% natural. We do not deal in synthetic or laboratory-grown material, and we do not hide anything about a piece: the photographs are shot to show every detail, including the ones a seller might prefer you did not see.
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.
