2.68 CT NATURAL COBALT BLUE SPINEL FROM SRI LANKA — GIA REPORT
A distinctive natural spinel with a refined green-blue appearance and vivid teal-blue flashes. Its elegant square cushion shape, transparent body, and modified step-cut pavilion produce crisp geometric brilliance and lively color as the stone moves through the light.
The accompanying GIA report identifies the gemstone as natural spinel and records its color as green-blue. GIA did not confirm the gemstone’s geographic origin, determine whether cobalt is present, or establish whether cobalt contributes to its color.
Accordingly, the descriptions “cobalt-blue” and “from Sri Lanka” are source-reported information rather than conclusions stated in the GIA report. Buyers should evaluate these descriptions accordingly.
GIA also states that no indications of heating were observed.
