Marquise cut diamonds, with their mix of vintage charm and sleek lines, are taking center stage in 2025 engagement ring trends. Featuring an elongated shape with pointed ends, this brilliant cut has a slimming effect on the finger if oriented North-South. But set them East-West and the Marquise gives distinctly modern vibes. Either way, more surface area means a Marquise diamond delivers more visual impact for its carat weight. What’s your favorite way to wear a Marquise? 💎 #IGI #MarquiseCut #EngagementRings #EngagementJewelry #EngagementRingTrends #Diamonds #MarquiseDiamond #2025JewelryTrends #DiamondGrading

It was an unforgettable time, meeting WONDERFUL guests who were very quick studies -- wielding their IGI loupes and analyzing gemstones like pros. Thank you to our hosts for their hospitality, and to all of the jewelry lovers and lifelong learners who joined us for their thoughtful questions, generous attention and terrific memories.

💙 Sapphires: How Geography Shapes Color 💙 Not all sapphires are created equal—their origin can shape their color, clarity, and overall character. 🌍✨ Sapphire’s blue color comes from titanium within the crystal - the higher the concentration the deeper the color saturation. 🔹 Kashmir Sapphires are coveted for their velvety, deep cornflower blue. These rare gems from now-closed Himalayan mines are considered some of the finest ever discovered. 🔹 Ceylon (Sri Lankan) Sapphires, known for their bright, vibrant blue, often feature excellent brilliance and clarity. Each gem tells a unique geological story. At IGI, our colored gemstone reports document the unique qualities and origins of sapphires to ensure confidence and authenticity. Which blue hue do you prefer??💎Let us know in the comments! ⬇️ #SapphireOrigins #KashmirSapphire #CeylonSapphire #MadagascarSapphire #GemstoneReports #IGI #BlueGemstones #Sapphires #SapphireJewelry
