NATURAL RUBY — GIA DOCUMENTED — NO INDICATIONS OF HEATING
Offered is a 3.57-carat natural ruby accompanied by its GIA Ruby Report.
This is a particularly desirable characteristic because the GIA report states “No Indications of Heating.” GIA notes that most rubies on the market have been heated and that a GIA report confirming no evidence of heat can command a premium because of the rarity of unheated material.

Natural & Unheated
The GIA report confirms that this gemstone is natural ruby, rather than synthetic or laboratory-grown material, and specifically reports no indications of heating.
Please note that “No Indications of Heating” is not the same as a geographic-origin determination. Geographic origin was not requested on this report, so this listing makes no claim that the ruby is Burmese, Mozambique, Sri Lankan, Thai, or from any other locality.
Appearance
The ruby displays a rich purplish-red color with translucent body character and a classic oval mixed-cut design. The stone has a substantial 3.57-carat weight and measures approximately 10 × 8 mm, making it a very usable size for a statement ring or other custom jewelry piece.
