0.7 ct Round Lab-Grown Diamond Twin-Prong Solitaire Engagement Ring

Two slim prongs at each corner instead of one, so the round center sits secure without a cage of metal stealing its light. This is the entry size in the collection, a bright three-quarter-carat lab-grown round graded D color and VVS clarity. A round brilliant returns more light than any other cut, which is why even a smaller one throws real fire across a room. The twin-prong detail is quiet up close and invisible from a step back. Pick your metal below; each ring is set and sized to order.

Shown with a 0.7 ct lab-grown round (D color, VVS1 clarity, IGI certified) center for $1,559 total. Price shown is the complete ring; metal choice can change it. View the IGI certificate. Prefer a different diamond? Contact our concierge and we will hand-select it and quote the full all-in price.
