Purple Spinel 2.39 cts

The colour in Purple Spinel is primarily governed by trace amounts of chromium and iron within its magnesium aluminium oxide crystal structure, with the precise ratio between these elements determining whether the stone leans toward pink, lavender, or deeper violet. Unlike many gemstones, Spinel achieves this colour entirely naturally — it is one of the very few gem species that is almost universally untreated. This makes the colour you see completely authentic to the stone’s formation over millions of years.

Spinel’s crystal structure — isometric, with no double refraction — means light passes through it with a clarity and directness that gives its colour a pure, undiluted intensity rarely matched by Amethyst or Tanzanite. At 2.39 carats, this stone sits in a weight range where the colour saturation is fully expressed, as smaller Spinel can sometimes appear lighter in tone. Collectors specifically seek this combination of weight and hue depth because it is proportionally uncommon in fine-quality material.

Spinel registers 8 on the Mohs hardness scale and has no cleavage, making it a genuinely durable gemstone well-suited for everyday wear across all jewellery settings. Routine care is straightforward — warm soapy water and a soft brush are sufficient, and the stone is safe for ultrasonic cleaning under normal conditions. Unlike certain other coloured gems, Spinel is highly stable and does not require special storage or protection from light exposure.

For Spinel of this calibre, certification from a recognised laboratory such as GIA, Gübelin, or SSEF is the standard of due diligence, particularly to confirm the absence of heat treatment and, where possible, to provide an origin determination — as Burmese and Mahenge material commands meaningful premiums. The market for fine Spinel has matured considerably over the past decade, with auction results and dealer pricing reflecting growing recognition among serious collectors. Purple and violet hues remain among the less commercially saturated shades within the Spinel spectrum, which supports considered long-term value for quality examples.
