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.

IMPORTANCE OF PREVENTATIVE CARE

To keep your Black Diamonds New York jewelry looking its best, we recommend following a few simple care instructions. By incorporating these practices into your daily routine, you can ensure that your jewelry maintains its brilliance and remains an everlasting symbol of your individuality.

MAINTENANCE TIPS FOR LONG-LASTING BEAUTY

3. Store your jewelry in a soft cloth or jewelry box to prevent scratches and tangles.
4. Clean your jewelry regularly using a mild soap and warm water. Gently scrub the pieces with a soft brush and rinse thoroughly.
5. Schedule regular check-ups with our jewelry specialists who can inspect and clean your jewelry professionally.

HPHT DIAMONDS (High Pressure High Temperature Diamonds)- These are real 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.

Black rhodium silver or gold is dark grey to black in color plating. It is a very intricate process and varies each time. Plating longevity is very much dependent on the individual and the environmental conditions it is exposed to (e.g. 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. We offer free re-plating up to 3 months.
