Size: Size 12 ● Type ・Natural Sapphire ・Species: Natural Corundum ● Origin ・Geographic Origin: Sri Lanka → Blue sapphires from Sri Lanka are highly regarded. ● Heat Treatment ・No Indications of Heating ● Color ・Color: Blue While it's impossible to fully judge the color's depth from the photos, GIA generally only lists the color name. ● Transparency ・Transparency: Transparent → Indicates high transparency, which is a positive factor in the evaluation. ● Cut ・Shape: Oval ・Cutting Style: ・Crown: Modified Brilliant Cut ・Pavilion: Step Cut → Combination of brilliant cut on the top and step cut on the bottom. This finish aims to provide both brilliance and depth. ● Size ・9.58 × 7.28 × 6.61 mm → Equivalent to approximately a 4ct class size (Sapphires have a specific gravity of about 4, so this volume is reasonable for around 4ct). ✅ Color Impression — Soft depth typical of unheated stones You can clearly see bright blue flashes rising within the deep blue. • "Not too dark, doesn't appear black" • "Seems to maintain a deep blue even in natural light" • "Gives a sense of the 'depth of blue' characteristic of sapphires" This clearly exhibits the color characteristics found in high-quality, unheated Sri Lankan stones. ✅ Clarity — Quite good within the visible range from the surface • No significant cloudiness or haziness visible on the surface • Light reflection lines pass through beautifully Unheated stones often contain natural inclusions, but it appears to be at a level where no noticeable flaws are visible to the naked eye. ✅ Cut — Light doesn't sink, and reflections are uniform • Strong white reflections from the brilliant cut on the top • Blue flashes of internal reflection scattered throughout • Almost no "windows" visible This is evidence of good cut balance. ✅ Details — Excellent compatibility with the setting • Radiant design (sunburst) with tapered baguette diamonds • The center stone is large, so the "scene" is very wide • Overall, it's a high-jewelry grade
