For a example, a brooch, which has a lot of details of high quality.

I found that next options may work:

***Ornate***

> 
> An ornate building, piece of furniture, or object is decorated with complicated patterns or shapes. **Collins**
> 
> 
> 

> 
> elaborately or excessively decorated **Merriam-Webster**
> 
> 
> 

***Filigree***

> 
> 1. delicate ornamental work of twisted gold, silver, or other wire
> 2. any fanciful delicate ornamentation **Collins**
> 
> 
> 

> 
> 1: ornamental work especially of fine wire of gold, silver, or copper applied chiefly to gold and silver surfaces
> 2: ornamental openwork of delicate or intricate design **Merriam-Webster**
> 
> 
> 

Which one is more idiomatic and why? Are there another options?
