BUYER QUESTION · Budget and Price
How much is a one-carat lab-grown diamond ring, and why do prices vary?
A one-carat lab-grown diamond ring has no single fixed price. The final price depends on color, clarity, cut, report and growth method, plus setting metal, weight, workmanship and service. Compare those fields side by side, then check live stock and price. JewelSpo public listings expose the SKU, current selling price and available stock for that comparison. The public snapshot has no in-stock ring with both a verified single center stone and about one carat of center weight. A multi-stone band's carat field cannot establish a comparable one-carat center-stone price.
