Whether you are shopping for a loose diamond as the first step of an engagement ring, an upgrade to an existing piece of jewelry, or for a new design, there is nothing quite like the brilliance and fire of seeing a diamond outside a setting.

By purchasing a loose diamond, you are able to get the best look at the stone to really see the4 C's up close cut, color, clarity, and carat weight. In this way, you can view inclusions that a setting might otherwise hide or distract from, allowing you to make an informed decision about the diamond you are investing in.

At Jianna Jewelers here in beautiful Houston, TX, we are proud to serve as the area's go-to diamond experts. We offer our customers an extensive collection of diamond shapes including round brilliant, princess, oval, cushion, and radiant cuts, and we carry diamonds graded by the most notorious gemological laboratories. 

Ask a Jeweler: What Is Diamond Color?

Like all of the 4Cs, diamond color is an important consideration when buying a diamond. While color affects price, there are a number of factors that can help you decide which color grade is right for you.

With the exception of some fancy colored diamonds, the most valuable diamonds are those with the least color. The color scale for transparent diamonds runs from D-F (colorless), G-J (near colorless), K-L (faint yellow), to Z (light yellow). Completely colorless diamonds are rare.

D color diamond is the highest grade and is extremely rarethe highest color grade that money can buy.

When diamonds are formed with traces of other minerals, rare and beautiful colors can result. These fancy colors range from blue to brilliant yellow to red, brown, pale green, pink, and violet. Because of their rarity, colored diamonds are highly desirable and may be quite valuable.

Keep in mind that color is more visible in large diamonds. If you are buying a diamond under 1 carat, you might consider choosing an I, J, or K color diamond. If you have your eye on a diamond over 1 carat, look at H color-grade diamonds or higher, since any color would be more visible.

If you have your heart set on a certain color grade and carat size that don't match the budget, consider a different shape. Certain fancy-shaped diamonds hide color better than othersand can cost significantly less than a round-cut diamond.

When setting your diamond, also consider the precious metal color of your setting so it can best compliment the color grade of your diamond. For example, yellow gold naturally casts a warm glow and looks best with diamonds with faint color, but platinum or white gold will make a near-colorless diamond look even brighter.
