Round Cut Diamond Buying Guide: What Every Couple Must Know

A round cut diamond spells perfection in all the right ways. Taking up 70% of the world’s polished diamond inventory, this piece of stone stands right at the top of the bling list.

Compared to round diamonds, every other cut seems like a compromise. It is the most expensive and popular cut in the market. If you can afford it, settle for nothing else.

Getting a premium round cut is like getting a Rolls Royce. It’s not only about the money, it’s about making a statement.

Picking the Right Round Diamond

Nothing shines brighter than a round diamond. This celebrity cut generally holds 58 facets and has impeccable brilliance. Owing to its craze, the diamond cut finds a seat among all pieces of jewelry.

Superior Cut Quality

Fire like no other, this cut’s radiance is above all. Choosing the right cut will give you the brilliance that this cut is famous for. With regard to choosing the right cut, here is all you need to know.

  • Depth Percentage: 61%-62.5%
  • Table Percentage: 54%-57%
  • Crown angle: 34º-35º
  • Pavilion angle:40.6º-41º
  • Girdle Thickness: Thin – Slightly Thick

These specifications will give you the best possible balance of fire and brilliance. The GIA grades cut quality from Excellent- Poor. Regardless, getting an excellent cut would be the best choice.

Color of Choice

Round diamonds hide inclusions in the best possible way. Their facet patterns and cut grades make them reflect light more than any other diamond. So this cut’s sparkle will conceal any visible color tints.

Don’t break your back over color grades. If you want a pristine white diamond, choose between D-F color grades. If you are paying a premium price it’s best to not slip below a G.

Based on your setting, you can play around with the color grade. For those preferring warmer tones, an H grade would work well with a yellow gold setting. Going down to even J or K grades is preferable if you are into warm tints and have a rose gold or a yellow gold setting.

The brilliance of a round diamond allows you to pick a lower color grade for those on a budget.

Clarity Grade

Higher Clarity will translate to better sparkle is a rookie mistake. An eye-clean VS2 diamond will look like a flawless diamond to the naked eye. Going for eye-clean SI1 or VS2 clarity grades will help you save a lot of cash.

Perfect Setting For Your Round Diamond Ring

When it comes to round cut settings, it’s a one-size-fits-all situation. Owing to their versatility and fame, they are used as engagement rings and more. From necklaces to stud earrings, everyone wants a piece of this diamond.

Halo Setting: Imagine a round diamond surrounded by a halo of melee diamonds. The brilliance of this design would be magnificent.

3 Stone Setting: A 1-carat round cut with two other flank diamonds, would bring out the bling. Experimenting with gemstones is also a great idea to highlight your round centerpiece. 3 stone settings are quite the rage among young couples. Show your loved one you care with 3 symmetrical rounds or a single round centerpiece. This setting holds the key to a lifetime of togetherness.

Why limit a round cut to a ring? The flawless nature of this cut has made it popular among all forms of jewelry. Round cut diamond necklaces and stud earrings are quite the rage. From elegant solitaires to everyday earrings, the round diamond is for all occasions. A star among diamonds, this cut is what everyone wants. But, can you afford one? What’s the best price? Let us find out.

Getting you the best deal for a Round Diamond

Keeping these things in mind will help you get a good price. Before you get excited, remember, this is the most expensive cut. Round cuts use the most diamond rough. In fact, only 40% of the original stone remains after being cut and polished. So this is not going to be cheap!

Here’s what you need to do first:

  • Settle on a budget: It’s important to know how much you will be spending. A promise ring and an engagement ring cannot be of the same value.
  • Avoid rookie mistakes: A higher clarity and color grade does not impact brilliance. Always go for an eye-clean diamond. A D/IF and G/SI1 diamond can look identical to the naked eye.
  • Concentrate on cut quality: An excellent cut round will have the fire you want. Compromising on Color and Clarity but not Cut will get you a stone of quality.
  • Know your setting: Choose the suitable carat weight for your setting. Don’t go for bulk if you are on a budget. A 1-carat round in a halo setting or a 3 stone setting is a smarter choice than a solitaire. Using melee diamonds or gemstones to highlight your centerpiece is also a good idea.
  • Find a reliable jeweler: Your jeweler can help you hit it home. You might end up paying more if you go for a brand. These diamonds are expensive and that’s a fact. You don’t want to be paying more than you have to. A trusted jeweler can get you the best stone for the best price.
