How Much Do Diamond Rings Cost in Singapore? (Tips on How to Choose)

Priscilla Lee

The story of boy-meets-girl can lead to a dream wedding. But before that, the boy will have to scout high and low for a wedding ring to impress his bride-to-be.

That’s not an easy task.

It isn’t just about getting a ring that fits your budget; you’ll also have to consider aspects like the design, authenticity, and quality of the gem. 

Read on because we’ve lined up tips that can help you decide on the right diamond ring for your partner:

What to Look For When Purchasing Diamonds

Before we talk about the price, there are six factors to consider when picking out a good diamond: Cut, Clarity, Carat, Colour, Shape, and Certificate.

1. Cut: How Much Light Does the Diamond Reflect?

A good cut will increase the gem’s beauty (and value). You’ll usually see gradings like Excellent (EX), Very Good (VG), Good (G), or Fair (F). At times you’ll also find jewellers using simpler grading like Good, Very Good, Ideal, and Aster Ideal

2. Clarity: Fewer Blemishes and Inclusions = More Valuable

Blemishes refer to external flaws, while inclusions refer to internal flaws:

3. Carat: The Physical Weight of Diamonds

Naturally, the bigger and heavier they are, the higher the price. One carat is equivalent to 0.2 grams.

4. Colour: Less Tainted = More Valuable

Most diamonds come with varying shades of yellow and brown, so look for one with minimal shades of yellow. The best colour grade starts with D and goes all the way to Z.

5. Shape: Rounder is More Common (And Often More Expensive)

Diamonds come in all shapes and sizes. Round diamonds tend to be the crowd favourite because they’re the most brilliant. Fancy cuts like Emerald, Radiant, and Asscher tend to be priced 10 to 43% lower than round ones.

6. Certificate: Quality Assurance

Always look for a diamond that’s been certified by a reputable gem laboratory like GIA, Hoge Raad voor Diamant (HRD), or the International Gemmological Institute (IGI). Such certification authenticates the legitimacy of the diamond.

Average Cost of a Diamond in Singapore

To show how the carat, cut, clarity, and colour impact the cost of the diamond, here’s a list based on a 0.5-carat diamond (without the ring) to help you understand:

As you can see, the difference in colour, clarity, and cut can jack up the price of a diamond of the same shape and carat. That’s why similar round diamonds can have vastly different price tags ranging from S$835 to S$2,790.

How to Decide Between Diamonds

If you’re shopping for a wedding ring, think about your priorities before picking up a ring. For example:

  • If the size matters but you have a limited budget, compromising the colour and clarity may be the solution for you
  • If quality counts, perhaps you can downsize the carat of the diamond

There is no right or wrong; just a matter of preference and priority. 

Don’t fret if your budget isn’t in the tens of thousands. There are wedding rings in the market going at a few hundred dollars. But if you’re looking for a quality 0.5 to 1-carat diamond ring, get ready to spend at least S$2,000.

Diamond Prices in Singapore, Sorted By Cut, Colour, and Clarity

Here are the prices you can expect to pay for a solitaire ring with the most sought-after round diamonds and less pricey Emerald-cut diamonds:

0.5RoundGoodK to HSI1 to SI2S$754 to S$1,755
0.5RoundVery GoodG to FVS2 to VS1S$1,625 to S$3,788
0.5RoundExcellentE to DVVS2 to IFS$2,072 to S$5,282

0.5EmeraldVery GoodE to DVVS2 to FLS$1,217 to S$4,822

For 0.5 carat rings, the Emerald-cut diamond rings are about 33% cheaper than round diamond rings while 1-carat ones are as low as half the price even with similar colour, cut, and clarity.

So if you want a ring to impress but lack the budget, consider an atypical shape of diamond. You can still get decent clarity, colour, and cut but at a much lower price than one with round diamonds.

Alternatively, look around for rings with diamonds in other shapes like Radiant, Cushion, and Asscher. These are classic shapes with broad surfaces great for showing the brilliance of the diamond – but priced lower.

Here’s a chart to compare the value (in USD) of fancy-cut diamonds with round ones.
