2.9–3.1mm Sapphire — Pair (2) — Vivid Royal Blue

2.9–3.1mm Sapphire — Pair (2) — Vivid Royal Blue These 2.9–3.1mm Sapphires have a beautiful mix of medium to deep royal blue tones, ranging from bright cornflower blue to rich, saturated cobalt blue. Their vibrant color and lively faceting create brilliant flashes of blue, making them especially striking as focal stones or paired accents in a jewelry design. Sapphire is a variety of corundum, prized for its exceptional hardness, durability and beautiful range of colors. Although best known for its classic blue varieties, sapphire occurs in nearly every color of the rainbow. Its blue color is primarily produced by trace amounts of iron and titanium. Sapphire has a hardness of 9 on the Mohs scale, making it an excellent choice for many jewelry applications. Sourced in: Thailand I hand selected these for my students. I have paired them as closely as possible in color and size in case they want to be used for a pair of earrings. Individual colors, clarity and inclusions may vary. Sizes are approximate and can vary as they are not calibrated. No refunds or exchanges.
