Buying loose diamonds is not as easy as seeing and paying the item. If you do not examine the stones, you end up paying a lot more than what the stones and the metals are worth. You might need to reconsider your preferences and your reason for wanting to buy loose diamonds. Every size and cut of a diamond stone portrays different kinds of ring personality. You need to consider and match the shape of the gem with your personality. Jewelers follow the 4C category in evaluating loose diamonds. The 4Cs are color, cut, carat weight, and clarity.
Loose diamonds color category
Flawless, clear, colorless loose diamonds are expensive and very rare. However, some may appear spotless to the naked eye but when placed under scrutiny on a jeweler’s microscope, show subtle yellow stains. If you try to compare a clearer flawless diamond from one that has subtle yellow shades, you won’t be able to recognize the difference without using a jeweler’s microscope. You may need to base your evaluation with the GIA color grading guideline scale. The grading scale created by the GIA helps identify best quality loose diamonds from inferior quality diamonds being sold in your local or online jewelry store. The GIA has developed the color chart for grading diamond stones.
Loose diamonds clarity
Flawless diamonds are much sought after stones because of its brilliance. The clarity of any diamond is the best way to determine internal flaws and cracks. Flawless diamonds have higher valuation and command higher price from buyers too. The diamonds make fine pieces of jewellery when place on metals. However, only 1% of available diamonds being sold online are 100% flawless. Most of them have low quality and are just great as fillers. GIA has a list of categorizing diamond clarity for appropriate pricing.
