How to Buy Lab Grown Diamonds in Bangkok: A Complete Step-by-Step Guide
Buying a lab grown diamond is an exciting milestone, whether you're choosing an engagement ring, celebrating an anniversary, or investing in fine jewelry. While Bangkok offers many jewelry stores, understanding what to look for will help you make a confident and informed decision.
At Sphere Diamond, we recommend comparing diamonds in person whenever possible. Seeing a diamond under different lighting conditions, reviewing its certificate, and discussing your preferences with a diamond specialist can make a significant difference in your final choice.
| Step | What to Do | Why It Matters |
|---|---|---|
| 1 | Choose your jewelry type | Engagement ring, wedding ring, earrings, necklace, bracelet or pendant |
| 2 | Select your preferred diamond shape | Each shape offers a unique appearance, brilliance, and personality |
| 3 | Determine your budget | Balance carat weight, quality, and setting |
| 4 | Compare diamonds side by side | Observe sparkle, proportions, and overall beauty |
| 5 | Review the IGI Certificate | Verify grading and authenticity |
| 6 | Choose your metal | 18K White Gold, Yellow Gold, Rose Gold, or Platinum |
| 7 | Customize if desired | Create a unique piece that reflects your personal style |
Understanding the Diamond 4Cs
Every lab grown diamond should be evaluated using the internationally recognized 4Cs: Cut, Color, Clarity, and Carat Weight. Understanding these characteristics helps buyers compare diamonds objectively rather than relying on size alone.
| 4Cs | Description | Buying Tip |
|---|---|---|
| Cut | Determines how brilliantly the diamond reflects light. | Prioritize Excellent or Ideal Cut whenever possible. |
| Color | Measures how colorless a diamond appears. | D–F provides exceptional whiteness. |
| Clarity | Evaluates internal and external characteristics. | VS1–VVS2 often provides excellent value. |
| Carat | Represents the diamond's weight. | Balance size with cut quality for maximum beauty. |
Expert Tip
Many first-time buyers focus primarily on carat weight. However, a beautifully cut 1.20-carat diamond often appears more brilliant and attractive than a poorly cut 1.50-carat diamond. Excellent cut quality should always be a top priority.
Lab Grown Diamond vs Natural Diamond
One of the most common questions customers ask is whether lab grown diamonds are "real diamonds." The answer is yes. Lab grown diamonds possess the same physical, chemical, and optical properties as natural diamonds. The primary difference lies in their origin.
| Feature | Lab Grown Diamond | Natural Diamond |
|---|---|---|
| Composition | Pure Carbon | Pure Carbon |
| Hardness | 10 Mohs | 10 Mohs |
| Sparkle | Excellent | Excellent |
| Durability | Lifetime | Lifetime |
| Certification | IGI Available | GIA / IGI Available |
| Origin | Created in Advanced Laboratory | Formed Naturally Underground |
| Typical Price | More Affordable | Higher Price |
Did You Know?
Professional gemological laboratories grade lab grown diamonds using the same internationally recognized standards applied to natural diamonds. Both can receive detailed grading reports that evaluate cut, color, clarity, proportions, fluorescence, polish, symmetry, and measurements.
Why an IGI Certificate Matters
When purchasing a lab grown diamond, certification provides confidence and transparency. An independent grading report allows buyers to understand exactly what they are purchasing without relying solely on visual appearance. At Sphere Diamond, eligible center diamonds are accompanied by internationally recognized IGI certification.
| IGI Report Includes | Why It's Important |
|---|---|
| Carat Weight | Confirms the diamond's weight |
| Color Grade | Measures whiteness |
| Clarity Grade | Evaluates inclusions |
| Cut Grade | Determines brilliance |
| Measurements | Helps compare visual size |
| Laser Inscription | Matches the diamond to its certificate |
Which Diamond Shape Should You Choose?
The shape of a diamond influences not only its appearance but also how large it looks, how it sparkles, and how well it complements different hand shapes and personal styles.
| Shape | Best Known For | Ideal For |
|---|---|---|
| Round Brilliant | Maximum sparkle | Classic engagement rings |
| Oval | Elegant elongated appearance | Making fingers appear longer |
| Cushion | Soft romantic style | Vintage lovers |
| Emerald | Hall-of-mirrors effect | Minimalist elegance |
| Radiant | Modern brilliance | Contemporary designs |
| Pear | Unique silhouette | Fashion-forward buyers |
| Marquise | Largest face-up appearance | Maximum visual size |
| Princess | Sharp modern shape | Modern engagement rings |
Our Recommendation
If sparkle is your highest priority, Round Brilliant remains the benchmark for brilliance. If you prefer a larger face-up appearance without increasing carat weight significantly, Oval and Marquise shapes are excellent alternatives.

Buying Online vs Visiting a Boutique
While online shopping offers convenience, purchasing a diamond is often a once-in-a-lifetime decision. Visiting a boutique allows you to experience the sparkle, proportions, and craftsmanship of a diamond firsthand.
| Online Purchase | Visit Sphere Diamond Boutique |
|---|---|
| View images only | See real diamonds under multiple lighting conditions |
| Limited personal guidance | Professional diamond consultation |
| Cannot compare multiple diamonds easily | Compare several diamonds side by side |
| No opportunity to try on jewelry | Try different styles before deciding |
| Customization may be limited | Design your own jewelry from scratch |
Expert Recommendation
For engagement rings and high-value diamond jewelry, visiting a boutique provides a more informed buying experience. Seeing diamonds in person allows customers to evaluate brilliance, proportions, and craftsmanship beyond what photographs alone can show.
