Diamond Studs

Martini Lab Diamond Stud Earrings | Round Brilliant, DEF VS Ideal Cut, IGI Certified

$1,245.00

Round brilliant lab-grown diamonds, matched in pairs and hand-set in 3-prong martini settings. In solid 14K gold or platinum, made entirely to order.

Three prongs form a low, open cup that sits close to the earlobe, using minimal metal so the diamond gets maximum light and maximum sparkle. The most modern and flattering of the classic stud silhouettes.

Every pair is IGI certified lab-grown: DEF color. VS clarity. Ideal cut. Matched for carat weight, spread, table proportions, and fire so both sides mirror each other when worn.

Available in solid 14K white gold, 14K yellow gold, 14K rose gold, or platinum. Push backs, screw backs, or La Pousette locking backs.

Made entirely to order. Allow 8-12 business days from order to shipment.

Diamond Education

The 4 Cs, Read the Way a Gemologist Reads Them

Cut

How well the diamond returns light. The most important C: a poorly cut diamond looks dull no matter how large or clear it is. We only set Excellent and Very Good cut grades.

Color

How colorless the diamond is, graded D through Z. For studs, H to I is the sweet spot: the stones read white in the ear at a fraction of the cost of D to F grades.

Clarity

Internal characteristics, graded from Flawless to Included. Earrings are viewed at arm's length, never under a loupe, so eye-clean stones read flawless in the ear. Our gemologists verify every stone we set is eye-clean.

Carat

The weight and visual size of the stone. Studs are listed by total carat weight across the pair, so 1/2 ct. t.w. means each ear carries a quarter carat.

Questions, Answered

Before You Decide

What does ct. t.w. mean?

Total carat weight. The listed weight is split across the pair, so a 1/2 ct. t.w. pair carries a quarter carat in each ear. Jewelers list studs by the pair total because that is how the pair reads when worn.

Are these natural or lab grown diamonds?

These studs are set with lab grown diamonds, chemically and optically identical to natural diamonds and graded on the same scales. We also offer natural diamond studs as a separate line if you prefer that route.

What if I want different specifications?

Talk to a jeweler. Our gemologists can source the same setting with different carat weights, clarity grades, or metals, and will walk you through the trade-offs before you decide. Guidance is always complimentary.
