Short Answer

Choosing stud size is about balance: your ear, hairstyle, lifestyle, and budget. In Sandy Springs, most clients land on 0.50–1.00 ctw for daily wear, while special-occasion buyers go 2.00–3.00 ctw. Lab-grown studs offer the same sparkle at a lower price, letting you choose larger sizes within the same budget. Natural diamonds are valued for rarity and tradition.

FAQs

What stud size is best for everyday wear?

Most people prefer 0.50–1.00 ctw pairs for a balanced, office-friendly look. Smaller lobes may like 0.33 ctw; larger or thicker lobes can comfortably wear 1.00–2.00 ctw. We’ll size you in-store so the post length and back style fit perfectly.

Do lab-grown studs look different from natural?

No—both are real diamonds with the same hardness and sparkle. Lab-grown options usually cost less, allowing a larger size within the same budget. Natural options provide rarity and tradition.

Which backs are most secure?

Screw backs and guardian/La Pousette backs are the most secure; friction backs are quick and low-profile. We’ll match the back to your lifestyle and chosen size.
