What to Know Before Going

Before visiting Philadelphia’s Diamond District, you should know these things to make your diamond shopping experience smooth:

  • Budget: Determine your diamond spending limit. Setting a budget will help you choose and avoid overspending.
  • Know What You Want: Discuss diamond shape, size, and style with your partner. Guidance will help you find the right diamond.
  • Look for physical stores: Philadelphia’s Diamond District has many trustworthy jewelers. Look for long-standing stores with high-quality diamonds and great customer service. Reading reviews and asking for advice can help.
  • Certifications: Always request a diamond certification or grading report from a non-seller gemological laboratory like GIA or AGS. This document details the diamond’s quality and features.

Let’s explore the most critical aspects of diamond buying—the four Cs.

Knowing the 4 Cs

Before discussing the other three Cs of diamonds, we must discuss carat weight. Carat weight is crucial to diamond valuation. The cut of a diamond also affects its appearance and brightness. Finally, diamonds’ color and clarity are graded on scales to determine their quality and value.

Carat Diamond

The carat weight of a diamond is an important factor in understanding the four Cs of diamond quality and value. Diamond carat weight affects its appearance and price. Diamonds tend to grow with carat weight.

But the diamond’s carat weight shouldn’t be the only factor in its value. Remember that diamond prices rise with carat weight. Diamond prices vary greatly depending on factors such as carat weight and others. When considering carat weight, balance size and quality to maximize value.


The diamond industry grades cut quality as excellent, very good, good, fair, and poor. Diamonds with excellent or very good cut grades sparkle. The diamond’s cut is its symmetry, polish, and proportions. It affects diamond light flow. A well-cut diamond bends and reflects light to look it’s most fiery and beautiful. 

However, a poorly cut diamond may appear lifeless. The following details explain diamond-cut parts:

  • Diamond symmetry: It is its shape and facets’ accuracy.
  • Diamond polish: It refers to its smoothness.
  • Proportion: Balance and relationship between diamond sizes like depth and table size is proper proportion.
  • Diamond brilliance: The brilliance of a diamond is its white light reflection.

A color

Since we’ve discussed cut, let’s discuss color, another of diamonds’ 4 Cs. Consider color grade when buying a diamond because it indicates whether a white diamond is yellow or brown. Diamonds are graded from D (colorless) to Z (light yellow or brown). Diamonds become more valuable as they become colorless.

Consider diamond certificates. Make sure the diamond you buy has a GIA or AGS certificate. Certification ensures the diamond’s color grade. Many people prefer almost colorless white diamonds. Some people prefer fancy yellow or pink diamonds. Color grade can greatly impact a diamond’s price. Diamonds with better color grades are usually more expensive.


Diamond clarity is crucial when learning about diamonds’ 4 Cs. Clearness measures diamond flaws or inclusions. These flaws can alter the stone’s appearance and value. FL diamonds are natural masterpieces with no flaws or inclusions under 10x magnification. Its flawless beauty captivates hearts. Internally Flawless (IF) has minor flaws that are visible under magnification. 

This diamond is remarkable for its beauty and near-flawlessness. VVS inclusions are elusive even under 10x magnification, displaying excellent quality and brilliant sparkle. Finally, the VS, or Very Slightly Included, diamonds sparkle and shine, with inclusions visible only under magnification. Diamond selection is special because each clarity grade evokes a different emotion.
