Why Round Diamond Studs are the Ultimate Earring Staple

If you’re looking for an earring that is elegant, timeless and versatile, round brilliant-cut diamond studs are the go-to classic. Whether dressing up or keeping it casual, there’s something about that perfect round cut that flatters every face, style, and moment. Here’s everything you should know when choosing the perfect pair. 

What is the Round Brilliant Cut?

- The round brilliant cut is engineered for maximum light return. Its facet arrangement (58 facets, or 57 if there's no culet!) is designed so that light entering the diamond is reflected, refracted, and dispersed optimally.

- It is almost invariably the best choice when you want “sparkle.” This diamond shape outperforms many other shapes in real‐world wear.

- Its symmetry and proportions are crucial: a well cut round brilliant maximises what you see, even if the carat weight is moderate.

Key Factors to Consider When Buying Round Brilliant Studs

- Carat Weight / Visual Size: Choose a carat weight that balances presence/versatility e.g. subtle everyday studs at 0.25-0.50ct per ear to bold sparkle at 0.75-1.00ct or more.

- Cut Quality: Always prioritise Excellent or Ideal cut grades, since cut has the biggest impact on brilliance and sparkle.

- Colour and Clarity: Opt for near-colourless grades like G–H and eye-clean clarity ranges such as VS2–SI1, which offer a bright look without unnecessary overspending.

- Matching Pair: Ensure both diamonds are closely matched in cut, colour, and clarity, as even small differences are noticeable in studs worn side by side.

- Setting and Metal: Select a setting and metal that suits your style and lifestyle - prongs for maximum sparkle or bezels for added protection. 

Choosing Your Perfect Pair

Here’s a quick checklist to go through before you buy:

1. What carat size feels right for you (comfort, style, budget)?
2. Can you see the sparkle and fire under regular lighting?
   
3. Is the setting solid and protective enough (especially for active wearers)?
4. How well do the two diamonds in the pair “match”?
5. Is the jeweller offering a certificate for studs above 0.30ct each?
