Ruby sits in a category where identity and treatment both need checking: red spinel and pink-to-red sapphire have long been confused with ruby, and heating is routine enough that its absence has to be shown rather than asserted. Report #2245032085 identifies the material as natural corundum, natural ruby, at 1.65 ct and 7.77 x 5.98 x 4.39 mm, color Red, with No Indications of Heating under Additional Results, and gives Madagascar as GIA's geographic origin opinion.\u003c\/p\u003e\n\n\u003ch2\u003e\u003cspan role=\"text\"\u003e\u003cstrong\u003eKey Benefits of this Natural Unheated Ruby\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGIA-Documented Ruby\u003c\/strong\u003e\u003cbr\u003eIndependent identification of species and variety, with weight, dimensions and cutting style recorded, and Madagascar given as GIA's origin opinion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnheated\u003c\/strong\u003e\u003cbr\u003eNo Indications of Heating, per GIA Report #2245032085 — a finding about heating specifically, not a statement that no other treatment was applied.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMadagascar Origin\u003c\/strong\u003e\u003cbr\u003eA significant modern ruby source, and GIA's geographic origin opinion for this stone.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOval Mixed Cut\u003c\/strong\u003e\u003cbr\u003eA brilliant-cut crown over a step-cut pavilion, as recorded on the report — an outline that sets easily in rings and pendants.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHard-Wearing\u003c\/strong\u003e\u003cbr\u003eCorundum is 9 on the Mohs scale, which measures scratch resistance.
