F. Silverman has just the diamond Bergen County jewelry shoppers are looking for, whether it’s for a thrilling engagement proposal, a birthday treat, or other special occasion. We recognize the importance of finding that perfect diamond, which is why we specialize in GIA-certified diamonds. The Gemological Institute of America runs the world’s oldest and largest independent diamond-certifying laboratory. The well-respected non-profit is known for having the strictest and most consistent grading standards. In fact, they pioneered the “4 C Grading System,” which assesses diamonds for: Carat Weight, Color Grade, Clarity Grade and Cut Grade. They also comment on the finish, symmetry and fluorescence.

Diamond mount options

We offer a full selection of platinum, 18k and 14k mountings for you to choose from for a complete package. We feature a wide selection of men’s and ladies’ wedding bands in diamond, platinum, 18k and 14k and alternative metals. Choose from various shades of gold, including the popular white gold, as well as rose and yellow gold. For the budget-minded consumer, there are platinum, silver, copper and brass options that dazzle recipients and complement the primary jewels fantastically. Customers often ask about the various differences in settings.

Common questions about diamonds include:

  • Platinum or White Gold? Platinum and White Gold are popular jewelry setting materials because they are both valuable, expensive and weighty. However, there are a few differences. White gold starts as yellow gold, but takes on a whiter appearance when pure gold is alloyed with other stronger metals. These rings are often rhodium-plated for shine and strength. Platinum is 40-60% heavier than gold, is slightly rarer and more expensive, and is 90-95% pure platinum (compared to 58% pure gold when purchasing 14k white gold). At F. Silverman, we recommend 14kt gold (58% pure) if you want jewelry that is relatively low-maintenance, slightly more durable and scratch-resistant, and more intricately designed. We recommend 18kt (75% pure) if cost is not so much a factor and you’re looking for jewelry that is heavier-feeling, yellower in appearance initially and deepens in color in a complex way with a beautiful patina over time. The difference matters less with White Gold, as most are equally shiny and are nearly all rhodium-plated.
  • 14k or 18k Gold? One-hundred-percent pure gold is 24-karat. Unfortunately, this form is impractical in jewelry making because the gold in its natural form is too soft to be durable. Therefore, the gold is blended with harder metals to ensure that your investment lasts as long as your love.

How to choose the best diamond at F. Silverman

All our diamonds are customized to meet your specific shape, color, cut and clarity requests. Choosing a shape is a highly personal matter based on preference alone. We offer: round, square (princess), heart-shaped, pear-shaped, oval, marquise and rectangular diamond shapes for your consideration.

When selecting the perfect diamond, you will want to consider:

  • Clarity: The top clarity rating is “FL” (for flawless), which is found in less than 1 in 5,000 jewelry-quality diamonds. With the clearest diamonds, there are no visible imperfections when viewing under a microscope with 10x or greater zoom.From there, you can choose “IL” (internally flawless), which is found in less than 3% of diamonds and appears virtually perfect unless viewed by an expert using 10x magnification.Next comes “VVS1” and “VVS2” (very very slightly included), which have minor flaws that are imperceptible to the untrained eye but can be viewed under 10x magnification from the pavilion or the crown.“VS1” and “VS2” flaws can be observed by 1 in 100 observers under ideal conditions and even “S1” and “S2” flaws are often invisible to the naked eye.


  • Color: The highest color grades possible include “Colorless” diamonds (D, E, F), which may contain the slightest amount of color only perceptible to a trained gemologist under a microscope. You should only choose truly “colorless” diamonds if you are considering white gold or platinum settings, as the yellow-gold will reflect some color no matter what. “Near Colorless” diamonds (G, H, I, J) contain traces of color and are far more common, so they offer great value. The price tends to increase 10-20% with each subsequent grade level. Again, we recommend these color grades for platinum and white gold customers.The warm tone of “Faint Color” diamonds (K, L, M) are perfect for yellow or rose gold customers. A K diamond is generally half the price of a G diamond due to its perceptible hues. 


  • Cut: Cut is the biggest factor in assessing the beauty of a diamond. Though it can be hard to quantify, the GIA assesses diamonds based on their brilliance (the brightness of white light reflections on the surface and interior of the polished product), fire (the dispersion of light and flashes of visible color), and scintillation (the sparkle or flashes of light and dark when the diamond is moved in the light).The ideal cut is “Excellent,” showing maximum fire, brilliance and sparkle. Next is “Very Good” with superior fire, brilliance and sparkle that is on par with “Excellent” in most normal lighting conditions. “Good” reflects a majority of light entering the diamond for an above-average level of fire, brilliance and shine. “Fair” allows the light to escape from the sides or the bottom of the diamond, reducing fire and brilliance, but still carries a high degree of sparkle – particularly in diamonds that are less than 0.75 carats in size.Keep in mind, the shape of the diamond you choose very much influences the cut. For instance, round diamonds look best in “Excellent” or “Very Good” cuts, but fancy shape diamonds look just as well in “Good” or “Fair.”


  • Carat: People often think of carat in terms of size, but it actually describes the physical weight of the diamond. One carat weighs approximately 0.2 grams – about the same as a paper clip. In general, you can find better value in a smaller carat diamond that grades higher in terms of perfection than a larger diamond with less brilliant qualities. You will, however, want to consider factors such as: the size of the wearer’s finger, the size of the setting, and budget. Diamond prices increase at full and half-carat weights.The choice all boils down to wearer preference and expectation. There are people wearing 0.25-carat engagement rings that are simply stunning and a beautiful testament to the relationship, as well as 4-carat rings that impress onlookers with their generosity at first glance.

  If you are looking for an exquisite diamond but are working within a limited budget, we have several options for you:

  • Drop down to SI1 or SI2 clarity if your diamond is under one carat.
  • Drop down to L-M color paired with yellow-gold if you have a brilliant cut diamond under 1.5 carats.
  • Opt for a “good” cut round diamond or a “fair” cut fancy diamond.
  • Reduce your carat weight target or look for a size just below a popular carat standard (1/2 or 3/4-carat, for instance), as these are often indistinguishable to the beholder and sold at a slight discount.
