Hi! Rarity plays a huge role, but it’s not the only factor. Color intensity, clarity, cut, and origin all shape a gemstone’s value. Rare gemstones like Russian alexandrite or Ural demantoid garnet, for instance, fetch high prices due to both scarcity and striking visual qualities. In high end jewelry, value also comes from the craftsmanship around the stone—how it's set, how the piece ages, and its overall design integrity. Tsarina Jewels https://tsarinajewels.com/ is a great example of this layered value—they focus on rare Ural stones and bring out their best through expert cutting and balance. A rare gem alone is valuable, but how it’s presented can multiply its worth.
