Shopping for a diamond can be an exciting adventure. However, for most first-time diamond shoppers, it usually comes with concerns -- primarily around the price! Due to the beauty, ethically sourced, and lower price points in comparison to mined diamonds, lab grown diamonds are a very popular option. But how much should you really expect to spend?
In this blog, we will go over the factors that determine lab grown diamond prices, the differences between lab grown diamonds and mined diamonds, and what you can expect to pay for lab grown diamonds of different carat weights so you can feel more confident in the process.
What Are Lab Grown Diamonds?
Lab grown diamonds are in fact real diamonds, they are created in a controlled lab environment rather than mined from the earth. Using advanced technology, scientists replicate the natural conditions that form diamonds underground—high pressure and high temperature or chemical vapor deposition—resulting in sparkling stones with the same chemical, physical, and optical properties as mined diamonds.
To the naked eye, ethically created diamonds look identical to their earth-mined counterparts. They exhibit the same sparkly colorless appearance, hardness & durability, can be graded and certifies by respected gemological laboratories like IGI or GIA. The primary difference between lab grown and mined diamonds is where they come from and how they provide a more sustainable, ethical option for consumers nowadays.
How Are Lab Grown Diamonds Priced?
Like mined diamonds, lab-created diamonds are priced based on a combination of factors that determine their beauty and rarity. The major factors that influence price include separated into five categories:
- Carat: The weight of the diamond. Larger stones are more rare and therefore higher price.
- Cut: How well the diamond’s facets are proportioned and polished to reflect light. Well-cut diamonds appear more brilliant and valuable.
- Clarity: The presence (or absence) of tiny internal or surface imperfections known as inclusions. With higher clarity grades associated with higher price.
- Color: The degree to which a diamond is colorless. Stones closer to pure white are generally more sought-after.
- Shape: Certain shapes, like round brilliant, tend to cost more because of its exceptional brilliance and sparkle resulting in higher demand and the additional rough diamond lost during cutting.
Together, these factors—commonly known as the 4Cs plus shape—play a big role in determining the final price of a lab grown diamond. By understanding how they work, you’ll be better equipped to balance your preferences with your budget.
Lab Grown vs. Mined Diamond Prices: What’s the Difference?
One of the main reasons lab-grown diamonds are becoming so popular is their price. Lab diamonds typically cost 80–95% less than equivalent mined diamonds, on average.
This price difference doesn’t mean lab-created diamonds are inferior—they’re chemically and visually identical to mined stones. The difference is through more efficient production methods and a supply chain that does not depend on traditional mined diamonds. Lab-created diamonds can be grown in a matter of months while it takes billions of years for mined diamonds to be formed underground; therefore, it is a more predictable and less resource-intensive process.
For the consumer, this means you can usually get a larger carat or higher quality diamond for the same money you would typically spend on a smaller mined diamond. The lower price is one of the main reasons why so many couples and collectors are choosing lab grown diamonds without sacrificing any beauty or authenticity.
Why Are Lab Grown Diamonds More Affordable?
Lab grown diamonds are less expensive to buy primarily because of how they are made. Unlike mined diamonds which require an expensive process of finding and sourcing a diamond from the earth, lab grown diamonds are made in a controlled facility using high technology. This process can avoid many of the costs and eco-impacts of traditional mining.
Another reason lab grown diamonds cost less is supply. While natural diamonds take billions of years to form, lab created diamonds can be created in a matter of weeks or months. This makes production more predictable and helps keep pricing more stable over time.
The end product is a beautiful stone that is certified and has the same sparkle and durability as mined diamond—often at a much more affordable price. For many consumers, this affordability means they are able to purchase a larger carat weight, a higher clarity grade, or a more unique shape without breaking their budget.
1 Carat Lab Grown Diamond Price
A 1 carat lab grown diamond is one of the most popular sizes for engagement rings and fine jewelry. Depending on the diamond’s Cut, Color, and Clarity, prices for a 1 carat lab grown diamond typically range between $300 to $1,200 USD. When it comes to diamonds, the price of a mined diamond with comparable specifications would range from $4,000 to $7,000 or more, so there is substantial value in a lab grown diamond without sacrificing quality or beauty.
If you are searching for a quality diamond that is both classic and an everyday size without overspending on a mined diamond, 1 carat lab grown diamonds are one of the best values available. This size is perfect for classic solitaire engagement rings, elegant pendant necklaces, and timeless stud earrings—pieces you can wear every day.
2 Carat Lab Grown Diamond Price
A 2 carat lab grown diamond makes a stunning statement. For this larger size, you are looking at prices between $800 - $3,000 USD, again dependent on the 4Cs and shape.
While a mined 2 carat diamond can easily exceed $20,000, lab grown options provide more accessibility for shoppers who want a showstopping stone. A 2 carat diamond is an optimal size if you enjoy a bolder beauty or if you want a ring that feels extra special but without the premium price tag.
A 2 carat diamond is also ideal for three-stone rings, an bold halo settings, or a standout pendant that becomes the focal point for any look.
3 Carat Lab Grown Diamond Price
Three carats of sparkle and brilliance is guaranteed to turn heads. Lab grown diamonds of this size typically start around $1,200 USD and can range up to $6,000 USD or more for stones with excellent cut and high color and clarity grades.
In comparison, a similar mined counterpart often costs upwards of $50,000–$80,000. Choosing lab grown makes it possible to enjoy a dramatic, luxurious diamond while keeping your investment more manageable. For milestone celebrations or one-of-a-kind rings, a 3 carat lab diamond delivers unforgettable impact.
A 3 carat diamond is perfect for high-impact luxe engagement rings, showpiece cocktail rings, or a gift like no other for an anniversary.
Tips for Buying Lab Grown Diamonds
When you are ready to select your lab grown diamond, some planning can help make the difference. These lab grown diamond buying tips can help you feel confident that you are getting the quality, beauty, and value you deserve.
Prioritize the 4Cs to Get the Best Value
Even though lab grown diamonds are cheaper than mined diamonds, the same 4Cs - cut, color, clarity, and carat- are still important. Start by focusing on cut, as it has the greatest effect on sparkle. Then decide which qualities you can compromise on for the price point of your budget. For example, many shoppers find that choosing a near-colorless grade and eye-clean clarity can free up budget for a larger carat weight or better cut.
Why Certification and Grading Matter
Always seek a diamond that is graded and certified by a reputable gemological laboratory such as IGI or GIA. Certification is a way to confirm your diamond’s authenticity and to provide a report of its 4Cs and other notable characteristics. This document provides added protection of your investment, and ensures you understand what you are buying.
