How to buy diamonds


It’s not every day you shop for a diamond. From an engagement ring to a thoughtful gift to celebrate a special occasion, diamonds are a symbol of love and commitment, so you want to make sure you’re getting a quality stone that makes an impression, but also makes sense for your budget and style. Before you start shopping, take a minute to read through our guide on how to buy diamonds the smart way.


A jeweler with a good reputation and access to the best diamonds on the market can help guide you towards the right diamonds for you. A good jeweler will listen to your ideas and style preferences and recommend a cut and setting that will make a diamond that fits your budget shine.

You don’t necessarily need a flawless diamond—you just need one that you love. Our diamond experts at House of Rajah Jewelers can help you create a truly one-of-a-kind piece that you’ll love for years.



The 4C's are the standards by which all diamonds are judged. A professional jeweler can help you navigate the diamond classification system and choose a stone that balances the 4C's to fit your unique needs.

The quality of every diamond is based on a combination of:


Considered the most important aspect towards determining diamond quality, the cut refers to the quality of a diamond’s angles, proportions, symmetrical facets, brilliance, fire, scintillation and finishing details. These factors all impact a diamond’s overall sparkle.

Color is graded in terms of how white or colorless a diamond is. For a standard diamond, the ideal color is none at all.

Refers to the weight of the diamond, not the size. For example, a 1 carat diamond weights 0.2 grams. Depending on the diamond shape and cut, two 1 carat diamonds could be very different in size.

A clear budget can help you prioritize when you’re shopping for a diamond. If price were no object, you could potentially spend upwards of $20,000 on the most flawless stone available. For most people, that isn’t necessary. You can get a beautiful diamond for much less—you just have to know what you want.

Not sure how much you “should” spend on an engagement ring? Maybe you’ve heard generic advice like you should be spending three months’ worth of your salary on an engagement ring or the bigger the diamond, the more expensive it is, but price can vary wildly based on the 4C's listed above and the style of jewelry you want. Narrow your search by setting your budget as early as possible and sticking to it.



You don’t have to buy the first diamond you see. Instead, shop around, browse and get acquainted with your options. Diamond jewelry is meant to be an investment so why rush into it? Enjoy the process of looking for a diamond that embodies everything it symbolizes to you. That way you’ll feel confident with your purchase and be happy with your choice.
