Choosing a diamond is one of the most meaningful purchases you will ever make. Today, buyers face a new question that simply did not exist a decade ago,should I choose a lab grown diamond or a natural, earth-mined one? Both are real diamonds. Both are beautiful. But they differ in ways that matter deeply to modern buyers.
This guide will walk you through every major difference,quality, price, certification, sustainability, and long-term value,so you can make a confident, informed decision.
Quality: Are They the Same?
In terms of physical and chemical properties, yes,lab grown and natural diamonds are identical. Both are graded on the same 4Cs: Cut, Colour, Clarity, and Carat. A lab grown diamond can achieve the same D-IF (colourless, internally flawless) grade as the rarest natural diamond. In fact, because lab conditions can be controlled, certain clarity grades are more consistently achievable in lab grown stones.
Price: The Most Significant Difference
This is where the gap is enormous. Lab grown diamonds typically cost 60–80% less than comparable natural diamonds. A 1-carat, D-colour, VS1-clarity natural diamond might retail for $3,500 or more. An identical lab grown stone can be purchased for $700–$1,000. That difference is not a compromise in quality,it's simply the removal of geological rarity from the equation.
For many buyers, this price difference means they can choose a larger stone, a better cut, or invest in a more elaborate setting,all within the same budget.

Certification: Who Grades Them?
Both lab grown and natural diamonds are graded by the same internationally respected laboratories,GIA (Gemological Institute of America) and IGI (International Gemological Institute). At Navratna Diamonds, every stone we sell comes with a full certification report detailing its cut, colour, clarity, and carat weight. You will always know exactly what you are buying.
Resale Value
Natural diamonds have historically held resale value better than lab grown stones. As lab grown supply has increased, their resale prices have softened. If long-term resale value is a priority for you, a natural diamond may be the better investment. However, if you are buying for the joy of wearing it,for a proposal, an anniversary, a milestone,lab grown gives you significantly more diamond for your money.
Which Should You Choose?
There is no universally right answer. Here is a simple framework to guide you:
- Choose Lab Grown if you want maximum size and quality for your budget, care about environmental impact, and are buying for emotional significance rather than investment.
- Choose Natural if resale and long-term investment value is a priority, or if the geological story of the diamond carries personal meaning to you.
