How Much Does a Real Diamond Ring Cost? Can You Buy One on a Budget — Even Under 1,000+ Baht?

If you’re shopping for a beautiful diamond ring — whether it’s for an engagement or a wedding — you might be wondering how much a real diamond ring actually costs. Diamonds are known for their beauty, rarity, and high market demand, so naturally, people assume they come with hefty price tags.

But the good news is: Diamonds are available in a wide range of prices, and it’s absolutely possible to find one within a budget — even in the thousands of baht range. Plus, there are plenty of designs and settings to choose from.

How Much is a Real Diamond Ring?

The price of a diamond ring depends on various factors, especially:

• Carat weight

• Color

• Cut quality

• Clarity

Here’s a rough size guide:

• 1 carat diamond ≈ 6.4 mm

• 2 carats ≈ 8.1 mm

• 3 carats ≈ 9.3 mm

As of today, the price of a 1 carat diamond ranges from 80,000 to 600,000 baht, depending on quality. But if you're on a tight budget, you can still buy a smaller diamond at a lower price — especially if you go for diamonds under 1 carat, often measured in “points” or “tang” in Thai.

For reference:

• 1 carat = 0.2g or 200mg = 100 points (or tang)
  So you can look for diamonds of 10, 20, or 30 points to better match your budget.

The Ring Setting Affects Price Too

Beyond the diamond itself, the ring setting also affects the total cost. Common materials include:

• Gold (yellow or white)

• Platinum (most expensive)

• Silver

• Rose gold or pink gold

Among these, platinum is the priciest due to its durability and luxurious appeal.

Tips to Get a Good Diamond Ring at a Lower Price

Here’s a smart tip:
A 0.99 carat diamond is only about 1% smaller than a 1.00 carat diamond, yet it can be 5–15% cheaper! Why?

Because 1 carat is a psychological milestone. Owning a full 1-carat diamond just “feels” more valuable, which drives up its price disproportionately. If you're watching your budget, buying a 0.99 carat diamond can be a great way to save big without a noticeable size difference.

Can You Resell a Diamond Ring?

Yes, you can resell a diamond ring — just like gold. In fact, diamonds are considered a form of investment. Over time, as demand increases, diamond prices may rise.

However, the resale price depends heavily on the quality of the diamond and whether it comes with a certificate (especially from globally recognized institutes like GIA). Certified, high-quality diamonds are easier to sell and can command a better price.

Many people buy diamond rings from department store brand counters, but selling them back can be tricky. Often, you need to send the jewelry back to the company for authentication, which can take 1–2 months, and various fees may apply.
