Lab-grown diamonds are created using two different methods: high pressure and high temperature (HPHT) or chemical vapor deposition (CVD). Lab-grown diamonds are real diamonds with the same hardness, optical properties, and chemical composition as natural diamonds. Benefits of Lab-Grown DiamondsLab-grown diamonds have many benefits over natural diamonds.Lab-grown diamonds are ethically produced because they are not mined from the earth. All lab-grown diamonds are conflict-free.Lab-grown diamonds are less expensive than natural diamonds because there is an infinite amount of lab-grown diamonds that can be created. Where to Buy Lab Grown DiamondsLab-grown diamonds are available through many different retailers. Lauren B Jewelry in New York City offers a large selection of lab-grown diamonds in-store located on the third floor at 608 5th Avenue, New York, NY 10020. Antique Name, Modern FlairThe cushion cut diamond can be traced back to the old mine cut of the 1800s. Characterized by a high crown, a deep pavilion, and large facets, the cushion cut was made to glitter in low light. Our LAB Ready take on this soft square shape is made to modernize a long-time favorite.Our lab-grown antique cushion diamonds take center stage, whether they’re set in a three-stone ring or classic pavé band. The depth of the cut makes it the perfect choice for a variety of settings, from the simple, yet elegant basket to the lofty cathedral. It’s also ideal for showcasing our signature wrap design.Best of all, you can comfortably stack with a wedding band.Ring Terms to KnowThis small, delicate piece of jewelry only seems simple. Here are a few key terms to help you understand the anatomy of a diamond ring:Prongs: These small metal hooks holding the stone(s) in place. The center stone may have a horizontal band connecting the prongs; this creates a basket setting.Gallery: The area below the center-stone and above the shank of the ring. This is a great place to add some beautiful finishing touches to your ring.Shoulders: Shoulders refer to the two sides of the ring between the setting and the rest of the band.Shank: This refers to the rest of the band as it encircles the finger. The shank can include diamonds or gemstones, or be completely solitaire, and vary in size from ring to ring.We take pride in crafting quality, durable jewelry. Since lab-grown diamonds are as hard and strong as mined diamonds, these stones are made to last.
