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.

Frequently Asked Questions
What are the exact measurements of this Purple Sapphire?
This stone measures 10.6 x 8.2 x 4.9 mm and weighs 3.95 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 its high durability, this sapphire suits rings, pendants, and earrings alike. Your jeweller can mount it securely in either gold or platinum using standard claws or a solid bezel.
How does purple sapphire compare to pink sapphire or ruby?
All three belong to the corundum species and share the same hardness and crystal structure. The distinction lies entirely in the trace elements that produce the colour, with chromium and iron balancing to create the purple hue.
Is this stone suitable for everyday jewellery?
Yes, corundum is one of the hardest natural gemstone materials available. It resists abrasion effectively, making it a reliable choice for pieces worn constantly.
How should I clean jewellery set with this stone?
Wash the piece in warm water with mild washing-up liquid and a soft brush to remove everyday oils. Rinse thoroughly in 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.
