2 Carat Marquise Cut 18k Yellow Gold Lab Diamond Ring+ 2.0-Carat Marquise Lab Created Diamond

Yes. Lab diamonds are identical to mined diamonds in chemical composition, crystal structure, and optical properties. The only difference is origin: one forms underground over millions of years, the other is grown in a controlled lab environment. No jeweler can tell them apart without specialized equipment.

18k gold contains 75% pure gold, with the remaining 25% made up of alloy metals like copper and silver. This higher gold content gives 18k yellow gold a richer, more deeply saturated golden color than 14k. The trade-off is that it is softer and more susceptible to surface scratches compared to 14k.

A 2 carat mined diamond of good quality typically costs $12,000 to $25,000 or more. A lab-grown 2 carat stone of comparable cut, color, and clarity can be found for $1,500 to $4,000. The savings are substantial, which is why 2 carat lab diamonds have become one of the most popular upgrades couples make when they discover lab-grown options.

Yes. A 2 carat stone sits just a touch above the average diamond size in the US over the last two years. It gives the impression of slightly larger than average without looking too big or gaudy, making it a sweet spot for couples who want presence without excess. Its elongated, narrow outline covers significant finger length, making the stone appear larger than a round of the same carat weight. For buyers who want maximum visual presence from their budget, marquise is among the most efficient cuts available.
