This 3-Prong Lab-Grown Diamond Tennis Necklace is where precision meets presence. Available in 14K White Gold, 14K Yellow Gold, or 14K Rose Gold, it features round-cut lab-grown diamonds graded E-F color and VS clarity, ranging from 3 to 17 carats — so you choose exactly how bold you want to go.
The 3-prong setting is the key difference here. It holds each stone securely while exposing more of the diamond to light, maximizing brilliance and giving the necklace a cleaner, more open look compared to a 4-prong. The result is a line of diamonds that feels alive from every angle.
Crafted in solid 14K Gold, this necklace is built for both grand occasions and elevated everyday wear.
