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.
Why You Will Love This Gemstone
💎 Faceted Outline
The cushion outline offers rounded corners that fit securely into standard four prong or bezel settings without snagging on fabrics.
✨ Corundum Durability
High resistance to abrasion means your jeweller can set this sapphire tightly into a bezel without worrying about surface damage during the process.
🔷 Colour Distribution
Even saturation across the face up view ensures the material performs consistently under various lighting conditions once mounted in your chosen metal.

Popular Uses
Sapphire is a mainstay of fine jewellery. At Mohs 9 it is the hardest gem material after diamond and moissanite, which makes it very well suited to rings and bracelets that face daily contact. A Blue Sapphire of this size works particularly well as the centre stone in a bespoke piece.
Ideal For
- A bespoke jewellery project for a September birthday
- A custom sapphire ring built for daily wear
- A collector seeking fine corundum material
- A jeweller stocking benches for commission work

Frequently Asked Questions
What are the exact measurements of this Blue Sapphire?
This stone measures 5 x 4.8 x 3.8 mm and weighs 1.1 carats. Those figures are taken from the stone itself, not estimated from a category average.
What metal works best with this sapphire?
Platinum and white gold create a crisp frame that highlights the cool tone of the blue material. Yellow gold provides a warm contrast that leans into traditional jewellery aesthetics.
Can I wear this ring daily?
Corundum is exceptionally durable and resists scratching from everyday dust and debris. This hardness makes the stone an ideal candidate for rings worn continuously.
How should I clean the set stone?
Wash the piece using warm water, mild dish soap, and a soft bristled brush to reach behind the setting. Rinse thoroughly under clean running water afterwards.
How does the cushion cut behave in light?
Cushion cuts typically feature larger facets that produce broad flashes of light rather than the dense sparkle of a brilliant round cut.
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.

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.
