An oval-cut natural ruby from Madagascar, 0.36 carats, measuring 4.5x3.5mm. As an untreated stone, the color is entirely natural with no heat enhancement - the red shows a cooler, more muted tone compared to heated material, with the subdued, earthy quality typical of unheated Malagasy ruby. Clarity is I3, with inclusions clearly visible within the stone, which is consistent with untreated natural ruby at this price range. Most commercial ruby from Madagascar is heat treated as standard practice, so specifically unheated stones represent a distinct category for buyers wanting natural, unenhanced color or untreated status. At 0.36ct and 4.5x3.5mm, this oval works well for setting in a small ring or pendant, or as a loose untreated ruby for collection. Natural ruby, July birthstone.
