Buy Loose Diamonds- Remember the 4Cs

Some of the best shopping trips are those in which you get to buy loose diamonds. After all, it’s not every day when you come back with significant purchases like these. However, diamonds are a hefty investment, and you cannot afford to settle for mediocrity in return for your money. Thankfully, the GIA regulated a standardized method of judgment, which we refer to as the 4Cs of diamonds. 

By understanding these 4Cs, you’ll know how to pick apart the finest quality from the mediocre ones when you go to buy loose diamonds. Below is a detailed description of the 4Cs, which will be your best guide for your future trips. 

  1. Clarity 

Clarity is one of the most important 4Cs because it determines the rarity of a gemstone and also its value. If you peer closely at a diamond, you’ll find tiny markings inside it. According to the standardized grading scale that the GIA had regulated, the value of a diamond depends on the number of blemishes or internal characteristics or the lack thereof. 

If a jeweler describes a diamond as rare, it means that the stone has very few blemishes in them. In most cases, one can only see the internal characteristics through magnification but verifying it before purchase will ensure you get the clearest stone possible.

  1. Color 

There are several factors to consider when you’re out to buy loose diamonds, including the color. They say the more a diamond is devoid of color, the more valuable it is. You see, a diamond’s chemical purity and structural perfection influence its value of it to a large extent. 

If a diamond does not contain any hues at all, you will know that it is of the highest quality and worthy of buying. It must resemble a water drop to your naked eye if a perfect gemstone is what you want when you’re out to buy loose diamonds. You can refer to GIA’s color grading system, from D to Z, for this verification.

Grade D means the diamond is absolutely free of any color and thus, is an extremely valuable one. The more a stone’s grading leans towards the latter alphabets on the scale, the lesser their value will be due to the presence of color.

  1. Cut 

Many naïve buyers mistakenly assume that cut refers to the shape of a diamond. You must not make that mistake when you wish to buy loose diamonds at diamonds-USA. In reality, the cut of a diamond refers to the interaction between light and the many facets of a diamond. 

A diamond with a fine cut is one that disperses light tremendously well and sparkles all the more because of it. 

  1. Carat Weight 

Carat refers to the overall weight of the diamond. When you’re out to buy loose diamonds, be sure to remember the two-hundred milligrams mark. When you narrow down your options, remember to subdivide the carat weight into a hundred points and measure accurately till the hundredth decimal place value.
