What influences the price of a lab-grown diamond?
1. Carat
Carat represents the weight of the diamond and is one of the most important factors in determining the price.
As the carat increases, the price does not increase linearly, but exponentially.
For example:
* 1 ct diamond = reference price
* 2 ct diamond = does not cost twice as much, but can cost three or four times as much
Diamonds of 1-2 carats are the most sought after for engagement rings.

Color is classified on an international scale from D to Z.
The most valued diamonds are:

* E – almost perfectly colorless
* F – excellent colorless
At Estera Jewellery, most lab-grown diamonds are selected in colors E and F to provide an excellent balance between beauty and value.

Lab-Grown Diamond vs. Natural Diamond
Many buyers wonder if there are any visible differences.
The reality is that:
✔️ They have the same chemical composition
✔️ They have the same hardness (10 on the Mohs scale)

✔️ They can be IGI certified
✔️ They can be identified as genuine diamonds by professional instruments
The only difference is the origin.
Lab-Grown Diamonds are created in controlled environments using advanced technology.

Why are Lab-Grown Diamonds More Affordable?
The costs of mining are extremely high.
In the case of lab-grown diamonds:

In many cases, a lab-grown diamond can cost 50-80% less than a natural diamond with similar characteristics.
