Purple Sapphire Cushion Cut — Exquisite 3.35 Ct Loose Corundum

Cushion Cut Purple Sapphire

This Purple Sapphire is a natural Corundum gemstone weighing 3.35, cut in the cushion cut style and measuring 10 x 7.6 x 4.9 mm. It is a single stone, weighed and measured individually, and the photographs and video on this page were taken from it directly.

This purple sapphire displays a rich violet tone and a precise cushion cut that gathers light efficiently across the facets. Corundum possesses a robust crystalline structure that makes it exceptionally durable for everyday jewellery wear, maintaining its polished surface and sharp edges over years of active use.

Sapphire forms deep within the earth under high temperature and pressure, yielding a tough material prized by jewellers for secure prong or bezel settings. The cushion cut balances traditional facet geometry with modern brilliance, offering an adaptable shape that suits both minimalist mounts and elaborate halo designs.

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.

Care Instructions

• Clean this sapphire using warm soapy water and a soft-bristled brush to remove dust from the pavilion facets.
• Store the loose stone or finished jewellery piece separately in a fabric-lined box to prevent harder gems from scratching neighbouring items.
• Remove your sapphire ring before engaging in heavy manual labour or working with harsh chemicals.
• Avoid ultrasonic cleaners unless a gemmologist has checked the stone first.
