Fine stones above three carats are more difficult to find, particularly when they retain strong color and transparency.\u003cbr\u003e• Vivid orangy-red color: The stone displays a lively, saturated orangy-red hue rather than a dull, brownish or overly dark appearance.

This origin designation is presented as represented and is not independently confirmed by the GIA report.\u003cbr\u003e• Professional documentation: The gemstone is accompanied by the original GIA report, which identifies it as natural spessartine garnet.
