Open to everyone until Tuesday, September 29
To keep it, print it while it is open.
Precious stones cost a lot because good ones are rare, hard to extract, and often require careful cutting. A stone’s cut changes how it looks and how much buyers will pay.
In the picture
- Rock face at the mine entrance: where gem material is taken from the ground.
- Rough crystals in the cart: unprocessed stones before cutting.
- Faceted gem on cloth: a stone after cutting and polishing.
- Jeweller’s loupe: a tool for inspecting a stone’s cut and clarity.
- Balance scale: coins on one pan and a gem on the other, comparing money and stone.
Examples
- A diamond ring costs more than a similar-sized glass ring.
- A badly cut emerald sells for less than a well-cut one of the same weight.
Key takeaways
- Rarity and extraction costs push gem prices up.
- Cut quality is a major part of a gem’s market value.
