Start Here: Zero to Diamond in Under 10 Minutes


Welcome and relax - we got you! We know that buying a diamond can be stressful:

  • it is likely your first time buying diamonds
  • let’s face it - there may be pressure to get it right for your special someone
  • it is often a significant purchase
  • it feels complex - there are a ton of different terms. How do you get the right diamond and a good deal?
  • some diamond stores feels slimey and you don’t know if you are getting a good deal

In this guide we are going to help you find the perfect diamond in 5 easy steps and give you the knowledge you need along the way.

Step 1: Ballpark Budget

We need to pick a rough budget to keep us from going wild! Don’t worry - we can adjust it later. Our thoughts:

  • Ignore the ‘x2 your’ monthly income ‘rule’. This was invented by the diamond industry. The amount you spend should be driven by your finances and your preferences. (Remember, you may have an expensive wedding in a few months)
  • The average spend in the US is around $6000.
  • If you are socially conscious (that is ok!) then look around engaged or married friends. If you do have an idea of the size (carats) of ring you want you can look here to see the rough cost OneTrueRock market summary

Step 2: Ring Color & Metal

We now need to pick the ring ‘metal’. The easiest way to do this look at your partners favorite jewelry. This may be a ring or a necklace. What color is it? Is it gold or silver in color?

Partners Jewelry Color Recommended Ring Metal
Silver White Gold 14k
Gold Gold 14kt

Step 3: Ring Size

Next - the size of the ring. There are a couple of ways to do this:

  • Our recommendation is to keep it simple and buy a $6.50 ring sizer from Amazon (Be careful not to get it delivered to your home if you live with your special person!)
  • Drop your partners favorite ring onto the tool and you have an accurate size. This gives the maximum likelihood that the ring slides on perfectly the first time.

There are a other ways from tracing rings on paper/soap and taking them to a jeweler or online tools to estimate ring size. However, these are messy or inaccurate.

If your special person does not wear any rings and it is a surprise you will have to get sneaky/creative.

Remember: Most rings can be resized. It is easier to decrease the size of a ring versus increase. If you are unsure - err on the side of slightly too large vs slightly too small.

Step 4: Diamond ‘Shape’

Next we have to pick the ‘shape’ of the diamond. There are many shapes but the majority of diamonds are one of three shapes.

Recommendation Example
Round is the classic and most common shape. 3 in 4 engagement rings are round.

Pick this if your partner has classic style or values tradition.
Princess diamonds are the second most common.

Pick this if your partner has contemporary style.
Cushion cut are the third most common shape.

Pick this if your partner is more romantic or quirky.

Step 5: Quick Diamond Education

Size, Quality, Cost

You have probably been bombarded by a bunch of terms - the 4Cs, Cut, Clarity, Color, etc

We want to give you a simpler way of thinking about diamonds. You can think of a diamond in terms of

Term Definition
Size How big does the diamond appear? We will go into quality in a later post. For the moment, size is measured in Caratweight
Quality How good does it look? We want white, sparkly and free of blemishes is the diamonds
Cost How much does it cost?

It is that simple! We want the biggest and highest quality diamond within your budget.

For the moment let’s breeze over the details of size or quality. We cover them in more detail in later posts.

How Size and Quality Change Cost

Now you may be saying

“Great! I want a HUGE and PERFECT QUALITY without SPENDING too much”.

Because real diamonds are formed via geological processes large and perfect quality diamonds are rare and expensive.

Increasing the size or quality increases the cost.

Size↑ + Quality↑ = Cost ↑↑

The table below shows how cost for different size (CaratWeight) and quality of diamonds.
