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

  • it may be your first time buying diamonds
  • let’s face it - there is some social pressure
  • it can be a significant purchase
  • there are all these different terms
  • 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 (thats 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.

We want to give you a simple and clear way of thinking about diamonds. All you need to consider is three factors:

Size How big does the diamond appear? We will go into quality in a later post. For the moment, size is measured in Carats.
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 latr 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 expensive.

Increasing the size or quality increases the cost.

Size↑ + Quality↑ = Cost ↑↑

Let’s look at this in practice for three different diamonds all for roughly $10,000.

Option Size (Carats) Quality Cost
Perfect Quality but Small 0.98 Flawless under microscope $9,481
Great Quality and Medium Size 1.50 Flawless to human eye $9,941
Larger but Poorer Quality 2.01 Visible flaws to the human eye $9,736

Crazy! For the same budget there very different size and quality.

You are probably saying ‘the perfect quality one was too small’ and ‘the large one, while large, didn’t look that good’.

I want the ‘goldilocks’ diamond which is both good looking and big!

Step 6: Pick the Diamond

Picking the perfect diamond used to be complex - you have to become an expert, review hundreds of diamonds, avoid the bad deals and pick the right combination of properties.
