Compare each size on the same model. White gold keeps the focus on the diamond rather than changing the visual with metal color.

Chosen With Intention

Beautiful diamonds without paying for differences that disappear on the ear.

My Jewelry Guy Take

G–H–I color and SI clarity strike the right balance for marquise diamonds at these sizes: bright, lively, and thoughtfully priced. At this scale, moving into higher paper grades can add cost without creating a meaningful visual difference for most customers. I would rather recommend a well-matched pair with attractive sparkle and honest value.

Designed for Real Life

Distinctive enough to feel special. Simple enough to reach for often.

The marquise silhouette brings more personality than a traditional round stud without making the earrings difficult to style. Two-prong settings with protective V-prongs keep the pointed tips secure while allowing the elongated outline to remain visible.

Choose Your Gold

Same design. Three different personalities.

14K White Gold

A crisp, bright look that keeps the visual focus on the diamonds.

14K Yellow Gold

Classic warmth and contrast that makes the marquise outline feel rich and distinctive.

14K Rose Gold

A softer, romantic finish that gives the clean stud design personal character.

Frequently Asked Questions

What customers usually want to know.

Does CTW refer to each earring?

No. Carat total weight is the combined diamond weight of the pair.

Which size is best for everyday wear?

Choose 1/6 CTW for a delicate look, 1/3 CTW for balanced presence, or 1/2 CTW when you want the marquise shape to stand out more clearly.

Why G–H–I color and SI clarity?

Those grades provide an intentional balance of attractive appearance and value at these sizes. The goal is a bright, well-matched pair—not paying extra for distinctions that may not be meaningful on the ear.

Are these sold as a pair?

Yes. The earrings are sold as one matched pair with friction backs included.

How long will my order take?

These earrings are made to order. Please allow approximately 3–5 weeks for production before shipping.
