In Singapore, discerning buyers value both beauty and trust when it comes to diamond rings. That’s why many turn to reputable jewellers like Michael Trio, known for quality craftsmanship, transparent pricing, and customisation options that cater to every couple’s story.
This 2025 guide walks you through everything you need to know before buying a diamond ring in Singapore — from how much it costs, to understanding the 4Cs, exploring popular styles, and discovering where to buy the perfect ring.
Most Searched: “How Much Does a Diamond Ring Cost in Singapore?”
One of the most common questions from buyers is: “How much should I spend on a diamond ring?”
The answer depends on several factors — mainly the diamond’s carat size, type, and quality.
💎 Average Price Ranges in Singapore (2025):
| Carat Size | Natural Diamond | Lab-Grown Diamond |
|---|---|---|
| 0.3 carat | From S$700 – S$1,500 | From S$400 – S$900 |
| 0.5 carat | From S$1,500 – S$4,000 | From S$800 – S$2,000 |
| 1.0 carat | From S$4,500 – S$10,000+ | From S$1,800 – S$4,000 |
These are general ranges — actual prices vary with cut, colour, and clarity.
Lab-Grown vs. Natural Diamonds
- Natural Diamonds are formed over billions of years beneath the Earth’s surface. They’re prized for their rarity and traditional appeal.
- Lab-Grown Diamonds are real diamonds, created in controlled environments using advanced technology. They offer identical beauty at up to 40–60% lower prices.
At Michael Trio, both options are available with GIA or IGI certification, ensuring authenticity and quality no matter your preference.
Factors That Affect Diamond Ring Prices
- The 4Cs – Cut, Colour, Clarity, Carat
- Setting Design – Solitaire vs Halo, metal type (18K gold, platinum, etc.)
- Brand Reputation & Craftsmanship
- Certification – Certified diamonds retain value better.

Understanding the 4Cs of Diamonds
The 4Cs — Cut, Colour, Clarity, and Carat — determine a diamond’s beauty, brilliance, and value. Knowing how to balance these helps you get the best sparkle for your budget.
1️⃣ Cut (Most Important)
The cut defines how well a diamond reflects light.
A well-cut diamond appears bright and fiery, even if it’s smaller in size.
- Grades: Excellent → Very Good → Good → Fair → Poor
- Tip: Always prioritise cut quality — it has the biggest visual impact.
At Michael Trio, every diamond’s cut is carefully graded and verified by GIA or IGI, ensuring maximum brilliance.
2️⃣ Colour
Diamonds are graded from D (colourless) to K.
- Colourless diamonds (D–F) are premium, while near-colourless (G–I) offer better value.
- Tip: For white gold or platinum settings, choose D–H; for yellow gold.
3️⃣ Clarity
Clarity refers to how flawless a diamond is.
- Grades: FL, IF, VVS1–VVS2, VS1–VS2
- Tip: Choose VVS1 or VS1 for great value — inclusions are usually invisible to the naked eye.
4️⃣ Carat
Carat, not size, is a measure of weight. The cut of two diamonds with the same carat might change how they appear.
- Tip: A 0.9ct diamond often looks identical to a 1.0ct but costs significantly less.
✅ Balancing Quality & Budget
If you’re aiming for the best sparkle within budget:
- Prioritise Cut → Colour → Clarity → Carat (in that order).
- Opt for slightly lower grades in non-visible aspects to save without compromising beauty.
Michael Trio offers a wide selection of GIA- and IGI-certified diamonds, letting you compare options side-by-side to find the perfect match of brilliance and value.
