culet 🔊
Meaning of culet
The small flat facet at the bottom of a gemstone, particularly a diamond, which is parallel to the larger flat surface (the table) on top.
Key Difference
The culet is a specific part of a gemstone's cut, distinguishing it from other facets like the crown or pavilion.
Example of culet
- The diamond's culet was so small that it was almost invisible to the naked eye.
- A pointed culet can sometimes cause durability issues in a gemstone.
Synonyms
base 🔊
Meaning of base
The lowest part or edge of something, especially the part on which it rests.
Key Difference

Example of base
- The base of the statue was inscribed with the artist's name.
- He examined the base of the wine glass for any chips.
facet 🔊
Meaning of facet

Example of facet
- Each facet of the diamond reflected light brilliantly.
- The jeweler polished every facet to perfection.
pavilion 🔊
Meaning of pavilion
The lower part of a cut gemstone, below the girdle.
Key Difference
The pavilion consists of multiple facets, while the culet is just the single flat facet at the very bottom.

- The pavilion angles affect how light exits the diamond.
- A well-cut pavilion enhances the gem's brilliance.
point 🔊

Example of point
- The point of the needle was incredibly sharp.
- She broke the pencil's point while writing.
table 🔊
Meaning of table
The flat top surface of a cut gemstone.
Key Difference
The table is the largest top facet, while the culet is the smallest bottom facet.
Example of table

- A larger table can make a gem appear bigger.
girdle 🔊
Meaning of girdle
The narrow band around the widest part of a gemstone, separating the crown from the pavilion.
Key Difference
The girdle is the outer edge, while the culet is the center of the bottom facet.
Example of girdle
- The girdle of the ruby was slightly rough to the touch.
- A thick girdle can make a gemstone more durable.
bevel 🔊
Meaning of bevel

- He smoothed the bevel of the wooden plank.
apex 🔊

Key Difference
Like 'apex,' 'vertex' refers to the highest point, whereas 'culet' is the bottom facet.

- The vertex of the pyramid was perfectly aligned with the stars.
- The vertex of the triangle was marked with a dot.
Conclusion
- The culet is a crucial part of a gemstone's cut, affecting both its appearance and durability.
- While 'base' is a general term, 'culet' is specific to gemology and refers only to the bottom facet of a gem.
- A 'facet' can be any flat surface on a gem, but the 'culet' is always the bottommost one.
- The 'pavilion' includes multiple facets, whereas the 'culet' is just one small part of it.
- A 'point' refers to a sharp end, but a 'culet' is flat and parallel to the table.
- The 'table' is the top facet, opposite in position to the 'culet' at the bottom.
- The 'girdle' is the outer edge, while the 'culet' is centered at the base.
- A 'bevel' is an angled edge, unlike the flat 'culet'.
- Both 'apex' and 'vertex' refer to the highest point, contrasting with the 'culet,' which is the lowest facet.
