So, before buying a diamond engagement ring for your loved one, let’s learn more about diamond grading and pricing.
How is a diamond rated?
Carat:
Carat is the weight of the diamond. The heavier the diamond, the higher the price tends to be. Since 1913, the worldwide standard has been 200 milligrams, or one-fifth of a gram, per carat. Learn more about diamond carat weight and how it can affect a diamond’s value.
Shape:
Round is often among the most expensive diamond shapes. Princess, Oval, Cushion, Emerald, Marquise, Heart, Pear, Asscher, Trapeze, and other non-round shapes are frequently referred to as fancy shapes.
Color:
The presence of yellow or brown color can affect a diamond’s price. Higher color grades generally indicate less visible body color, with colorless diamonds being among the most sought-after. You can learn more about the diamond color scale and how different grades influence value.
The various natural colors found in diamonds include white, black, steel grey, blue, orange, yellow, red, pink, green, purple, brown, and more. Some of these are classified as fancy color diamonds and are evaluated differently from traditional colorless-to-yellow diamonds.
Cut grade:
To understand how a diamond reflects light, the cut grade is one of its most significant characteristics. It helps indicate how well the diamond’s proportions, symmetry, and finish contribute to its sparkle and brilliance.
Clarity:
Clarity is graded based on the internal inclusions and external blemishes found in a diamond. Natural diamonds can contain various inclusions and blemishes, and their size, number, and location can influence the clarity grade and overall appearance of the stone.
Proportion:
The symmetry and proportions of a stone are analyzed as part of the diamond grading process. How well the diamond is proportioned and finished can influence how it interacts with light and, consequently, its overall appearance and value.
GIA Diamond
The term GIA stands for “Gemological Institute of America.” It is an organization focused on the research and education of gemstones and gem jewelry.
Since 1931, GIA has been a leading authority on many aspects of gemology. GIA has contributed to the development of important innovations in the jewelry industry, including advances in gemological equipment and diamond grading practices.
GIA Diamond Report
A GIA Diamond Report provides an independent assessment of a diamond’s characteristics and quality. When purchasing a loose diamond, a grading report can provide important information about the stone and its 4Cs.
A GIA report can give buyers greater confidence by providing an independent evaluation of the diamond’s characteristics and confirming whether it is natural or laboratory-grown.
