Blue Green Bi-color Transparent Sapphire 0.88 CT | Queensland, Australia
This 0.88 ct transparent bi-color sapphire from Queensland’s Central Gemfields (Anakie, Rubyvale region) shows a refined “parti” palette cool royal blue transitioning to fresh yellow green in distinct, natural zoning. The oval mixed cut is well proportioned with crisp meet points and a bright vitreous luster, so the color change reads cleanly across the crown with lively scintillation. Sophisticated and modern, it makes a striking solitaire or a designer east west piece, especially in 18k yellow gold to echo the green or in platinum to sharpen the blue.
Species: Sapphire, corundum (Al₂O₃), uniaxial negative with pleochroism from blue to green; RI ~1.760–1.770, SG ~4.00, Mohs hardness 9 for exceptional durability. Australian sapphires are often routinely heated; treatment for this gem is not determined. The Queensland fields are renowned for collectible parti stones scarce, naturally zoned crystals prized by connoisseurs. Curated for Luminvault, this elegant 0.88 ct sapphire delivers pedigree, resilience, and a rare, painterly color split ready for a bespoke fine-jewelry setting.
