Jemlz powered by TDD Investments, LLC., has been delivering results since we opened in 1983. Our goal has always been to provide both a superior customer experience and add tremendous value for our customers.

We have nearly 40 years of experience in The Diamond District, NYC and we’re passionate about exceeding your expectations.


Why Us?

Fact: Pre-Internet shopping, we were the 1st to create the portal for ecommerce, an Internet Shopping Mall. We designed and developed a 44 page wholesalers-to-the-public website from which the very first diamond was sold online. As diamond importers and manufacturers of fine jewelry flood the market, we are still enjoying providing the industry with exceptional services and are now extending our convenient services to all online viewers globally.

Custom designs – we do it! Concept designs – we do it! We manufacture, we design, we cut and polish diamonds, we refine, we supply – we do it all. Our mission is to complete whatever is your fashion and your passion – all within whatever your budget details.

We have hand-selected reputable, trustworthy companies seeking to sell and promote their products and services. We have implemented additional secure payment methods like PayPal, Square and other trusted institutions for all financial transactions to be made easy and convenient via our secure credit processing.

This is a drop in the bucket of things available! We have been providing for the industry and feel it’s time to give back to you in more ways than one.

Before you make your purchase, do a little homework and check with your supplier, your father’s friend, your best friend’s friend’s friend or stop in at your local jewelry store and compare their prices with ours. With thousands of merchants in the US already connected to us, chances are that they process or purchase through us at some point or another.

Before making your next Jewelry Purchase, compare any jewelry item of your choice and we are sure we can match that price.
