A small oval-cut ruby from Madagascar in a softer, cooler pink with a faint grey undertone. Fine parallel silk runs diagonally across the body and is easy to pick out against the pale color, giving the interior a gently striped, silky texture. A small dark speck sits just above the center. The tone is even from edge to edge, and the overall surface has a satiny quality where the silk meets the polish. The fine needle silk visible here is common in Madagascar corundum and is what gives many ruby and pink sapphire crystals their soft internal glow. Heat is a standard, accepted treatment for ruby. Corundum's hardness of 9 makes it a durable choice even at accent size, and at 0.21ct and 4.3x3.4mm this oval suits earring pairs, side stones, or a compact pendant. Ruby is the July birthstone.
