Natural Diamond Engagement Rings
Where Long Island Gets Engaged
There is nothing quite like a natural diamond — formed over billions of years beneath the earth, every stone is entirely unique, with a depth and brilliance no other gemstone can replicate. At SVS Fine Jewelry in Oceanside, NY, we carry one of Long Island's largest selections of natural diamond engagement rings, with styles available to see, compare, and try on in person every day we are open.
Choose from hundreds of settings by Long Island's most sought-after bridal designers — Verragio, A.JAFFE, Gabriel & Co., Sylvie, and Noam Carver — and pair your setting with a GIA-certified natural diamond selected with guidance from our on-staff gemologists. Every ring can be customized to your specifications, and when you purchase your natural diamond with us, you are protected by our exclusive Lifetime Diamond Trade-Up Guarantee — allowing you to trade up to a larger stone in the future and receive full credit toward your next diamond.
