Lab grown diamonds are becoming very popular in the jewelry world. More people are choosing them because they look exactly like natural diamonds but cost less and are more eco-friendly. If you are planning to buy one, it is important to understand the types of lab grown diamonds and how to choose the right one.
In this blog, we will explain everything in simple words to help you make a smart decision.
What Are Lab Grown Diamonds?
Lab grown diamonds are real diamonds created in a laboratory using advanced technology. They have the same chemical, physical, and optical properties as natural diamonds. The only difference is that lab grown diamonds are made in labs instead of being mined from the earth.
They shine the same, are just as hard, and are certified like natural diamonds.
Why Choose Lab Grown Diamonds?
Before learning about the types, let’s see why lab grown diamonds are in demand:
- More affordable than natural diamonds
- Eco-friendly and sustainable
- Ethical choice with no mining impact
- Same beauty and durability as natural diamonds
- Available in many shapes and sizes
These benefits make lab grown diamonds a smart choice for modern buyers.
Main Types of Lab Grown Diamonds
There are two main types of lab grown diamonds based on how they are created:
1. CVD Lab Grown Diamonds
CVD stands for Chemical Vapor Deposition. This is the most popular method used today.
How CVD Diamonds are Made:
A thin diamond seed is placed in a chamber filled with carbon-rich gas. The gas breaks down and carbon layers slowly grow on the seed, forming a diamond.
Features of CVD diamonds:
- High clarity and quality
- More control over color and purity
- Usually more affordable
- Widely used in fine jewelry
- Can be grown in larger sizes
Why Choose CVD diamonds?
CVD lab grown diamonds are perfect if you want high quality, better price, and beautiful shine for everyday or bridal jewelry.
2. HPHT Lab Grown Diamonds
HPHT stands for High Pressure High Temperature. This method copies the natural diamond formation process.
How HPHT Diamonds are made:
Carbon is exposed to very high pressure and heat, just like inside the earth, to grow a diamond crystal.
Features of HPHT diamonds:
- Strong and durable
- Often used to enhance diamond color
- Good brilliance and fire
- Slightly higher cost than CVD in some cases
Why Choose HPHT Diamonds?
HPHT diamonds are great if you want diamonds with specific colors or those made using a natural-like process.
CVD vs HPHT: Quick Comparison
| Feature | CVD Diamonds | HPHT Diamonds |
|---|---|---|
| Quality | Very high clarity | Very good quality |
| Price | More affordable | Slightly higher |
| Color control | Excellent | Good for fancy colors |
| Availability | Widely available | Available but limited |
| Popularity | Very popular in jewelry | Used for special needs |
Both types are real diamonds. The choice depends on your budget, design, and preference.
