A facet calculator is a specialized tool used to determine the total number of facets on a gemstone based on its type and the number of gemstones you have. Facets are the flat, polished surfaces on gemstones that enhance their brilliance and beauty. Different types of gemstones have varying numbers of facets, and a facet calculator simplifies the process of calculating them.
The Formula of Facet Calculator
Let’s explore the formulas used for some common gemstone types:
Round Brilliant Cut Diamond:
- Crown Facets: 8 bezel facets + 8 star facets = 16
- Pavilion Facets: 8 pavilion main facets + 16 pavilion lower facets = 24
Princess Cut Diamond:
- Crown Facets: Varies but typically around 20-26 facets
- Pavilion Facets: Varies but typically around 4-8 facets
Emerald Cut:
- Crown Facets: Typically 25-29 facets
- Pavilion Facets: Typically 8 facets
Oval Cut:
- Crown Facets: Varies but typically around 35-40 facets
- Pavilion Facets: Varies but typically around 4-8 facets
Pear-shaped Cut:
- Crown Facets: Varies but typically around 25-30 facets
- Pavilion Facets: Varies but typically around 4-8 facets
Now that we have the formulas, let’s make it even more user-friendly by creating a table for general terms that people search for, making it easier for users without having to calculate each time.

Example of Facet Calculator
Suppose you have five round brilliant cut diamonds. Using the table above, you can easily calculate the facets:
- Crown Facets: 16 facets x 5 diamonds = 80 facets
- Pavilion Facets: 24 facets x 5 diamonds = 120 facets
- Total Facets: 80 + 120 = 200 facets
