How to Choose a Diamond Solitaire? (The 4Cs: Carat, Color, Clarity, Cut)

Diamond is the most sought-after stone for solitaire rings. It is prized for its unmatched hardness, unique brilliance, and powerful symbolism of eternity and fidelity. Before purchasing a diamond solitaire ring, it is essential to understand the selection criteria, which rest on four factors known as the "4Cs":

• Carat: corresponds to the weight of the stone. The higher the carat weight, the larger and more precious the diamond.
• Color: graded on a scale from D to Z. A D diamond is perfectly colorless; from M onward, a slight yellow tint becomes noticeable.
• Clarity: measures the presence of inclusions visible under magnification. The fewer inclusions, the rarer and more valuable the diamond.
• Cut: determines brilliance. It refers to how the diamond has been shaped to capture and reflect light. A well-cut diamond will outshine a larger but poorly cut stone.

What Is the Difference Between a Natural Diamond and a Lab-Grown Diamond?

Natural diamonds are mined from the earth after millions of years of formation. Lab-grown diamonds, on the other hand, are created in a laboratory by replicating the same pressure and temperature conditions. Both types share identical physical, chemical, and optical properties - the only difference is their origin. To the naked eye, it is virtually impossible to tell them apart.

Lab-grown diamonds are generally available at a lower price for the same carat weight, allowing you to get a larger stone for the same budget. They are also a more eco-conscious choice, as they require no mining.

What Budget Should You Plan for a Diamond Solitaire?

There is no simple answer, as the price of a diamond solitaire ring depends on several factors: stone quality, diamond type (natural or lab-grown), metal choice (9 or 18-karat gold), and setting style.

At Ocarat, our catalog features lab-grown diamond solitaires starting from 160€, up to several thousand euros for natural diamonds, to suit every budget.
