About Purple 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
๐ Faceted Character
The pavilion and crown facets are arranged to catch light across the violet face of the gem, creating a lively play of internal reflections.
โจ Setting Potential
Your jeweller can mount this cushion shape securely in claw or bezel settings for rings, pendants, or other custom jewellery projects.
๐ท Corundum Durability
Ranking just below diamond in hardness, this mineral withstands daily friction and maintains its polish well over years of regular use.
๐ฆ Exactly What Is Pictured
The photographs and video show this gemstone. You receive the gemstone pictured, not a lookalike.
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 Purple Sapphire of this size works particularly well as the centre stone in a bespoke piece.
Ideal For
- A bespoke ring project for a jeweller
- A September birthday gift for a collector
- A custom pendant commission
- A lapidary enthusiast stocking the bench

Frequently Asked Questions
What are the exact measurements of this Purple Sapphire?
This stone measures 11.5 x 9 x 5.2 mm and weighs 5.5 carats. Those figures are taken from the stone itself, not estimated from a category average.
Is this suitable for a daily wear ring?
Yes, corundum is one of the hardest gem minerals available. It handles the rigours of everyday rings without scratching easily.
How does this colour compare to blue sapphire?
Purple sapphire shares the exact same mineral family and durability as traditional blue sapphire. The violet hue comes from trace elements of chromium and iron within the crystal structure.
What setting style works best with a cushion cut?
A four or six claw setting allows maximum light to enter the pavilion. Bezel settings also look striking and offer extra metal protection around the rounded corners.
How should I clean this stone at home?
Warm soapy water and a soft bristled brush will safely remove everyday oils and dust. Rinse thoroughly with clean water afterwards.
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.
