This sapphire weighs 0.77 carats and is precision cut in a cut cornered rectangular measures 6 x 4mm so it will fit many standard mountings. A few things make this a very special gem, it's color is a very beautiful mix of pink and orange that will shift depending on lighting but always remains beautiful. Other factors contributing to it's rarity are its untreated in any way and eye clean with a very beautiful crystal (no silk at all!).
