In 1923
Erwin and his wife Betty opened their distinctive jewelry and gift shop at 410 Bedford Avenue in Bellmore. As one of the finest jewelers on Long Island, Mr. Von der Heydt was contracted to install the clocks at the West Bathhouse at Jones Beach.

A Neighbor You Can Trust
Buying jewelry is all about trust. You can trust us because we are an active part of your community for more than 100+ years. Our reviews online are incredible and speak volumes of the opinions of our long time and NEW customers! We are consultants to Law Enforcement agencies and trusted by their members. Insurance companies and law firms use and trust our professional services .We support local charities and volunteer our time to support local causes. We are here for you and your neighbors and will serve you above and beyond what a corporate business would because we know that word of mouth is the lifeblood of a local business. Make sure when you have a good experience, you tell your friends too!
Growing with You
As we get older, we sometimes get larger too. We will make sure your jewelry grows with you by resizing your rings and adding links to bracelets, necklaces, and watches. If you become very successful later in life, you may want to upgrade an engagement ring, without replacing it, by adding a match to your original center diamond and a larger center diamond between them. Our relationship with you will last a lifetime. In fact, for many families, it stretches for generations.
Individual Style
In a world where mass production and volume retail is becoming more common, many people settle for cookie-cutter jewelry. Volume retailers order every style by the thousands. You’ll see anything you buy there over and over, even when you travel to other towns. When you chose Gennaro Jewelers, you can select styles that have been handpicked or created just for your individual taste. In fact, we keep individual customers in mind when we go on buying trips and may select something just for you. You will receive individual service that you can never get from a huge corporation that buys in bulk for all its stores.
Not Just a Face in the Crowd
You are important to us: as a friend, a neighbor, and an individual, not just another face in the crowd. We will remember your anniversary and will even know which style your spouse tried on during a recent visit. And we will help you build a wardrobe that works: we can suggest some earrings to match a necklace you bought last year. When you take a big step in your life, like getting engaged or celebrating the birth of a child, we understand how important it is to make the moment match the emotion and can help you personalize your purchase.
Care & Cleaning
Not only do we care about you, but we care about your jewelry too! Cleaning rings, bracelets, necklaces, and earrings keep them beautiful. Bring them in any time for a FREE ultrasonic cleaning. In addition, bring in your rings every year or two to have the prongs checked to make sure that you never lose a gemstone. We offer this as a free service to customers. When your jewelry looks good, we look good too! Only a local jeweler cares to make sure that your jewelry stays beautiful forever…
Competitive Pricing
We travel far & wide to buy our diamonds direct from the source and choose each diamond we sell for maximum beauty and value. Don’t be fooled by the deceptive “50-80% off” offers that clog your mailbox: we offer you honest value every day.
Professional Advice
When you buy at a “chain store” or a mass merchant, the person behind the counter might have sold auto parts or ice cream the week before. When you choose Gennaro Jewelers, you will get the best advice from a true jewelry professional, that has years of jewelry experience and training. Our staff consists of trained professionals with a combined experience of 100’s of years! We have gemological training, read professional journals to keep up to date, travel to trade conventions and seminars and learn all about the products we offer. We can help you be an educated buyer and choose the jewelry that is just right for your lifestyle.
Authorized Dealers
We are an authorized dealer for all the brands we carry. This is especially important for watch brands, since “grey market” watches (commonly sold in foreign country’s), when you are on vacation, are often not covered by warrantees. We don’t sell “grey market” brands for that reason. The makers of respected brands know that we will stand behind their products with the right kind of product education and after-sales support. When you purchase a watch from Gennaro Jewelers, any common watch battery will be changed FREE, for as long as you own your watch! In addition, after your Gennaro selection, we will shorten your watchband…or lengthen it, at NO COST to you! As an authorized dealer, we also have access to the latest, most in-demand styles of the season. Make sure the brand you buy is legitimate, by purchasing it from Gennaro Jewelers.
Attention to Detail
We personally select each piece of jewelry and gemstone in our cases. We don’t sell jewelry from some central warehouse. Since we sell only what we ourselves carefully select, we have unrivalled quality control. When a mass merchant buys thousands of items, often deliveries are only spot-checked. Since we care enough to look carefully at every jewelry piece before buying it, shouldn’t you? If you buy from a website or from TV, the piece you receive may not be what you are expecting. At our store you can compare different pieces side by side, see the difference diamond qualities make, and also try on jewelry before you buy.
Designs of Your Dreams
If you’re not finding what you want, we can find it or make it for you. If it’s something simple, you might find it in the catalogs from our preferred suppliers and it can be special ordered for you.More importantly, we also offer custom jewelry, with your choice of design and gemstones. You can remake that “dated” design that you don’t wear anymore or make your jewelry dream a reality; it’s up to you, let us make your jewelry dreams come true. Our designers will sit with you and determine your taste and preferences. We will then illustrate the design and show you the progress every step of the way! Your complete satisfaction is our ultimate goal.
