visitors can shop directly for the exact diamond they want and then design or customize their own personalized jewelry pieces. Using the company’s proprietary Diamond Display Technology, consumers can view each of the site’s 150,000+ conflict-free, fully certified loose diamonds, as well as hundreds of ring settings, in 360° HD and zoomed up to 40x. JamesAllen.com operates almost exclusively online, with the exception of its by-invitation-only showroom in New York City.
