Diamond Stud Earrings FAQ

What does CTW mean for diamond stud earrings?

CTW, or carat total weight, refers to the combined weight of both diamonds. For example, a 2 CTW pair typically features approximately a 1 carat diamond in each ear.

What size diamond studs are best for everyday wear?

Diamond studs between 1 and 2 CTW are popular for everyday wear, offering noticeable brilliance while remaining versatile.

What is the difference between basket and martini diamond studs?

Basket settings offer a classic profile with four prongs, while martini settings use three prongs and sit closer to the ear while exposing more of the diamond.

Are Jacob Mercari lab-grown diamond studs real diamonds?

Yes. Lab-grown diamonds are real diamonds with the same chemical, physical and optical properties as natural diamonds.
