Diamond in the Rough

Another way to say “hidden gem” is “diamond in the rough.”

According to Merriam-Webster, a “diamond in the rough” is “one having exceptional qualities or potential but lacking refinement or polish.”

In other words, a “diamond in the rough” is something of great value hidden under a rough exterior. Therefore, its value may go unnoticed or unappreciated.

You can use the term “diamond in the rough” to refer to a person who may appear rough around the edges but has a very good character at their core. Thus, this phrase generally has very positive connotations.

Have a look at the example sentences below:

Sandor is a quintessential diamond in the rough; he comes across as brash and a bit rude, but he always does the right thing when the time comes.

My hometown is a diamond in the rough; beneath the dust and deary weather lives a truly loving community.


Another word for a “hidden gem” is “underestimated.” After all, a “hidden gem” is something very valuable that doesn’t get the recognition it is owed due to its underwhelming appearance.

Similarly, Merriam-Webster defines “underestimate” as “to place too low a value on.” This is a great alternative to go with since a “hidden gem” will inevitably be underestimated. A diamond that looks like stone won’t be considered very valuable, after all!

Moreover, it is easy to underestimate a person’s capabilities because of their appearance. After all, people often hide their exceptional skills and talents under a rather mundane façade.

Therefore, let’s see some examples making use of this term:

My team is often underestimated on account of its size, but you’ll find that I prioritized the quality of my agents over the quantity.

They underestimated me, and I suspect they will regret that decision.


“Hidden gems” will also frequently be “overlooked” since their value isn’t apparent at first glance.

Merriam-Webster defines “overlooked” as “not seen, noticed, or considered.” A “hidden gem” will not be noticed as much as an obviously pretty and valuable gem.

Similarly, a person may be “overlooked” if their talents or skills are not obvious at first glance. Therefore, the term “overlooked” has rather negative connotations.

See the examples below:

Despite being one of the greatest contributors to her genre, Tharpe was often overlooked.

Many times, the most important artifacts in the area are the most overlooked.
