Black Diamonds- New York's jewelry are handcrafted for daily wear, allowing you to showcase your timeless style and express your individuality every day. We take pride in the quality and durability of our jewelry, ensuring that each piece withstands the test of time. However, preventative care is recommended.

PERMANENT FINISH FOR SOLID GOLD JEWELRY

All our jewelry handcrafted in solid gold is treated with a permanent finish. This ensures that your favorite pieces remain as breathtaking as the day you first wore them. 

ELECTROPLATING AND E-COATING FOR SILVER JEWELRY

Each piece is electroplated with rhodium or finished with an e-coating, providing a layer of protection against everyday wear and tear. These finishes not only enhance the overall appearance but also provide added durability. However, it is important to note that these finishes are not permanent and require proper care to ensure their longevity.

BLACK FINISH JEWELRY: A TEMPORARY BEAUTY

We offer jewelry with stunning black finishes that complement our mesmerizing black diamonds. It's important to note that these black finishes are temporary and may wear off with frequent use. The longevity of the plating depends on the wearer and the level of care given to the jewelry. We have seen plating last anywhere from days, to months to even years.

NATURAL DIAMONDS – certified GIA, IGL, EGL, or DGI. Stones are guaranteed and certified. While our clear and colored diamonds have paperwork, our natural black diamonds will not come with a certificate. 

EVN™ DIAMONDS - These are our in-house lab-grown diamonds. The newest masterpiece of our lab using the same cutting-edge process as our CVD Diamonds. As we were searching for substitute for conflict-free diamonds, we stumbled upon this beautiful stone– brighter, shinier, and even more mesmerizing than any diamond we laid our eyes upon. Superiorly cleaner and flawless like a mined diamond. EVN™ Diamond has similar physical properties to natural diamonds, full of fire and identical to the naked eye. Each piece is carefully crafted into a masterpiece. With a quality that falls between our premium CVD diamonds and certified moissanite, our  EVN™ Diamond is a great choice for those seeking a balance between brilliance and affordability.

CERTIFIED MOISSANITE- professionally certified. These are near-colorless gemstones composed of silicon carbide, which is the same material that makes up natural diamonds. They are very durable and resistant to scratching and chipping with Mohs hardness of 9.25, which is just below that of natural diamonds (10). Our certified moissanite are known for their brilliance identical to natural diamond but at a fraction of the cost. Our selection boasts a variety of stunning colors, including classic clear, captivating black, and elegant yellow, green, and grey. Some colored moissanite features a coating for vibrant hues, which may require special care over time but every piece will pass the diamond test. Black Diamonds- New York's certified moissanite is among the hardest minerals on earth, more durable than sapphire, ruby, or emerald. 

PREMIUM CVD DIAMONDS (Chemical Vapor Deposition Diamonds)- These are lab-grown and atomically identical to mined diamonds and are composed of pure crystalline carbon. Our CVD process for these stones relies on a unique and innovative process that makes them look exactly like so-called “natural” diamonds. In fact, even a trained jeweler cannot identify the difference. Our Premium CVD Diamonds will pass the diamond test and can only be made available for stone upgrades at a premium cost. 

HPHT DIAMONDS (High Pressure High Temperature Diamonds)- These are lab-grown diamonds that are created using the high-pressure, high-temperature (HPHT) method. This method involves subjecting a small diamond seed to extreme heat and pressure, which causes the carbon atoms in the seed to bond together and form a larger diamond. HPHT diamonds are typically yellow or brown in color, although they can also be colorless or near-colorless. HPHT diamonds are typically more expensive than other types of lab-grown diamonds, such as CVD diamonds. This is because the HPHT process is more energy-intensive and requires more specialized equipment. However, HPHT diamonds are also considered to be more durable than other types of lab-grown diamonds.

DIAMOND ALTERNATIVE

SIMULATED DIAMONDS- Not mined diamonds but sparkle like one. It is difficult to distinguish the two with the naked eyes. Each stone is cut to maximize the radiance with the intent to create a collectible custom piece. Polished with natural diamond polishing wheels- the exact process to polish high-quality natural stones. Expert diamond cutters guarantee that our Simulated Diamonds are a cut above the rest. Premium stone with excellent cut, no one would know you did not spend a fortune. 

CREATED DIAMONDS - Not natural earthed diamonds but these are very expensive stones. The stones are made from zirconium dioxide that boast fine colour, no colour mixing, and a superb cut, which result in a beautiful duplication of nature. 

NATURAL GEMSTONES - We offer natural gemstones including amethyst, citrine, garnet, ruby, sapphire, emerald, morganite, peridot, topaz, aquamarine rose quartz, and tourmaline. Plus many more.

ARE THESE REAL DIAMONDS AND WILL PASS THE DIAMOND TEST?
All our Natural Diamonds, Premium CVD Diamonds, HPHT Diamonds, EVN Diamonds, and Certified Moissanites will pass the diamond test. Our Simulated Diamonds and Created Diamonds are lab-grown diamond imitators and will not pass the test. However, these are the BEST alternatives to natural diamonds. They look just the same, but they cost much less. At about only 1% of the cost of a diamond, you can take a stone that is equally beautiful and shining. Check our stone authenticity for more info.

DIAMOND CERTIFICATE
All our natural clear and colored diamonds with 0.40 carat and up will come with GIA certificates, our CVD/HPHT lab-grown diamonds will come with IGI certificates, and GRA certificates for all our Moissanite with .50 carat and up. Certificates for all custom-cut moissanite, and EVN Diamonds are only available upon request (before shipping). Natural black diamonds will not come with certificates.

FREE BLACK PLATING MAINTENANCE
Black rhodium silver or gold is dark grey to black in color plating. Black plating is a very intricate process and varies each time. Plating longevity is very dependent on the individual and the environmental conditions it is exposed to, water, soaps, natural skin oils, chemicals etc. Black rhodium is a temporary finish only, we have seen plating last anywhere from days, months to even years. This depends on how well it's looked after and also the natural oils in our skin. Black rhodium can be redone at any time.
