Calculate The High Wholesale Value Before You Buy Or Sell A Diamond
This calculator works as a guideline of value for most diamonds. It is not an indication of our purchase or sale price. We are very competitive in our valuations, but many factors go into pricing specific diamonds. This original Diamond Price Calculator™️ has been relied upon by millions across the world since 2005.
Sometimes you need a few tools to set your expectations before you set foot into a store. We invite you to use our Diamond Price Calculator, it's an excellent tool to approximate the high wholesale price or value of a loose diamond in US dollars.
Carat measures a diamond's weight, not its size as it is often confused. Five carats is equal to one metric gram, or, one carat is equal to 200 milligrams. The heavier the diamond, the greater its value. Small stones of high color and clarity are easier to find than larger ones, so you will notice them more often in jewelry stores.
Heavier stones, however, are harder to find, leading to greater value and use of supply and demand principles. Based strictly on weight, diamonds are incredibly valuable. The heavier the diamond, the rarer and the more valuable it is. Washington Diamond specializes in superior-quality, GIA-certified diamonds of all weights, ranging from one-half carat and up for engagement rings.
Clarity refers to how many inclusions, or spots and flaws, are in a stone. Generally speaking, fewer inclusions means a more valuable diamond, but flaws don't necessarily reduce a diamond's beauty, especially if they can’t be seen by the naked eye.
The majority of diamonds do contain some flaws, and most are inclusions of other minerals, created during crystal growth.
The system for grading clarity established and implemented by the Gemological Institute of America (GIA) is accepted by all diamond trading centers as the standard for diamond grading. It assesses diamond clarity according to size, position, color, and the number of inclusions or flaws present.
Diamond grading reports are issued by independent gemological laboratories. While there are several grading laboratories, Washington Diamond sells diamonds that are graded only by the Gemological Institute of America (GIA - GIA.edu).
It is our opinion that GIA has the most accurate and valuable standards that ensure proper quality in a diamond. A grading report recognizes quality characteristics identified in a uniform laboratory environment, which allows you to gauge and compare quality and value.
Cut deals with a diamond's proportions and angles, which determine how much it sparkles. The Cut is different from the Shape (such as round, princess, oval, etc.). There are five cut grades, ranging from ideal to poor.
A properly-cut diamond will refract the light that enters it and returns it through the top to produce the highly-desired sparkle. If the diamond is too shallow or too deep, some light will escape through the bottom, giving a shadowy appearance when viewed from the top.
