Round Lab-Grown Diamond Solitaire Engagement Ring

The round brilliant solitaire is the engagement ring that never dates. One round lab-grown diamond, held in a four-prong setting in 18K gold, with nothing competing for attention with the center stone.

Every center stone is a lab-grown diamond graded DEF color and VS clarity with an excellent cut grade: the top of the colorless range, cut for maximum brilliance and fire. Choose any weight from 1 to 30 carats, in 18K white, yellow or rose gold.

Choosing Your Gold

White gold keeps a colorless diamond looking its brightest and coolest. Yellow gold gives the ring a warmer, classic feel, and rose gold softens it. The diamond is the same in all three; the metal sets the mood.

Styling Tip

A round solitaire stacks easily. Pair it with a plain 18K gold band, or a slim eternity band in the same metal. See our lab-grown wedding and eternity bands.

Frequently Asked Questions

We welcome custom inquiries. If you'd like to explore a different scale, diamond ratio, or design variation, please use the Contact to Inquire button and our team will be happy to discuss options with you.

It comes down to your hand, your style and your budget. 1 to 2 carats is the classic everyday size. 3 to 5 carats has real presence on the finger, and 6 carats and up is a statement ring. Because lab-grown diamonds cost less per carat than mined diamonds, many clients choose a larger stone than they first planned. If you're between sizes, book an appointment and compare them on your hand.

Yes. A lab-grown diamond has the same chemical, physical and optical properties as a mined diamond. The difference is origin: it is grown in a lab rather than mined. Lab-grown diamonds are graded on the same color, clarity and cut scales, and every lab-grown diamond we sell is clearly disclosed as lab-grown.

All three work. White gold makes a colorless diamond look its brightest and most icy. Yellow gold is warm and classic, and rose gold is soft and romantic. If you plan to stack bands later, choose the metal you want the whole stack to be.
