Lab Grown Diamonds NYC

NYC Lab Diamonds is a lab grown diamond store and showroom on West 47th Street, in the middle of the Diamond District. We show engagement rings, loose lab diamonds, wedding bands and fine jewelry with a starting price on every piece, and we keep the stones out on a tray so you can see them in person before you decide anything.

Lab grown diamonds in NYC, seen in person

A photo on a phone tells you very little about a diamond. Two stones with the same grades can look different in your hand. One may face up a little bigger. One may hold more light from the side. You only see that when the stones sit next to each other on a tray, under a loupe, and then in plain daylight by the window.

That is why we work by appointment. You tell us what you are looking for, and when you arrive the pieces and stones are already out. There is no rush and no pitch. You can sit, compare, try rings on, and leave to think it over.

What a lab grown diamond is

A lab grown diamond is carbon crystal grown above ground, in a lab, instead of mined from the earth. It has the same chemistry, the same hardness and the same fire as a mined diamond. A jeweler with a loupe cannot tell them apart by eye. A grading lab tells them apart with special equipment, and every center stone we sell comes with an IGI or GIA report that says it is laboratory grown.

The real difference is price. A lab diamond usually costs far less than a mined stone of the same size and grade, so the same budget often buys a larger stone, a finer color, or both. If you want the details, read lab grown vs natural diamonds or are lab grown diamonds real.
