What Are Lab Grown Diamonds?
Understanding the basics of lab grown diamonds and why they're identical to natural diamonds
Lab grown diamonds are real diamonds created in laboratories using advanced technology. They have the same chemical makeup, crystal structure, and physical properties as diamonds formed naturally underground over billions of years.
Think of it like ice cubes - whether you make ice in your freezer or find it naturally frozen in a lake, it's still the same H2O. Lab grown diamonds are genuine diamonds, just made above ground instead of deep in the earth.
Key Facts:
- • Same hardness as natural diamonds (hardest substance on earth)
- • Same sparkle and brilliance
- • Same durability - will last forever
- • Only detectable with special equipment
- • Cost 30-50% less than natural diamonds
Understanding Diamond Quality (The 4Cs)
Every diamond is graded on four characteristics that determine its beauty and value
Every diamond is graded on four characteristics - Cut, Color, Clarity, and Carat weight. Here's what each means in simple terms:
Cut (Most Important)
How well the diamond is shaped and polished. This determines how much it sparkles.
What to buy: Excellent or Very Good cut. This makes the biggest difference in how beautiful your diamond looks.
Color
How white or colorless the diamond appears. Graded from D (perfectly colorless) to Z (light yellow).
What to buy: G, H, or I color grades offer great value. Most people can't see the difference from higher grades.
Clarity
How clean the diamond looks - measures tiny inclusions (natural birthmarks).
What to buy: VS2 or SI1 clarity. These look perfect to the naked eye but cost much less than flawless grades.
Carat Weight
The size/weight of the diamond. One carat equals 0.2 grams.
Smart tip: Lab grown diamonds let you buy larger sizes for the same budget. Consider 1.5ct instead of 1ct for dramatic impact.
CVD vs HPHT: Two Ways to Make Diamonds
Understanding the two main methods for creating lab grown diamonds
There are two main methods for creating lab grown diamonds. Both produce real diamonds, but they work differently:
🧪CVD Method
Uses gas and heat to build diamonds layer by layer, like growing a crystal.
⚡HPHT Method
Uses extreme pressure and heat to recreate how natural diamonds form underground.
Which Should You Choose?
For most buyers, either method produces excellent diamonds. CVD tends to be slightly less expensive and better for larger stones. HPHT excels at colored diamonds. Focus on the diamond's quality grades rather than the production method.
Diamond Certificates: Your Quality Guarantee
Understanding certification labs and what to look for on diamond reports
A diamond certificate is like a report card that tells you exactly what you're buying. Never buy a diamond without a certificate from a recognized lab - it's your proof of quality and authenticity.
Important: Here are the main certification labs you should know:
GIA (Most Trusted)
Global StandardThe Gemological Institute of America is considered the most reliable and strict grading lab worldwide.
