What is a lab-grown pink diamond?

A lab-grown pink diamond is a diamond made in a laboratory and has a pinkish tone that can range from faint pink to dark purplish pink. Lab-grown diamonds have the same chemical, optical, and physical qualities as natural diamonds. Lab-grown pink diamonds are rare and make up less than 5% of manmade diamonds. They’re typically much cheaper than mined diamonds. 

How are lab-grown pink diamonds made?

Lab-grown pink diamonds are made through Chemical Vapor Deposition (CVD) with irradiation that changes the permanent structure and color of the diamond. A diamond seed is placed in a sealed chamber and exposed to carbon-rich gasses and high temperatures. Depending on the pressure applied, these pink diamonds range from light pink to deep, rich pink.  

What makes a lab-grown pink diamond pink?

A lab-grown pink diamond gets its color from the low-pressure and irradiation processes that change the lattice structure. The process affects how the diamond absorbs and reflects light, giving off a pink color in various intensities. 

Unlike other fancy color diamonds that gain their color from impurities, pink diamonds get their color during their growth process. Pink diamonds are the second rarest of all fancy color diamonds, coming in right behind red diamonds

How much do lab-grown pink diamonds cost?

A 1 carat lab-grown pink diamond costs between $2,500 and $3,000 on average. The cost per carat weight increases with larger stones, because they’re rarer than smaller ones. You may pay up to $4,000 per carat for a large pink lab-grown diamond. 

As comparison, mined pink diamonds cost anywhere from $10,000 to more than $700,000 per carat depending on the color intensity.

Lab-grown pink diamonds vs. natural pink diamonds

Lab-grown pink diamonds have the same optical, physical, and chemical properties as natural pink diamonds. They look the same to the naked eye. Only a trained gemologist with a microscope would be able to tell the difference. 

Both mined and natural pink diamonds are rare and extremely durable. The biggest difference comes in resale value. Natural pink diamonds can be resold and maintain their value, while lab-created pink diamonds have no resale value.

Are lab-grown pink diamonds more environmentally friendly?

Lab-grown pink diamonds are usually considered more environmentally friendly because mining can have environmental repercussions. Pulling diamonds from the earth leaves a large carbon footprint, while manmade diamonds tend to offer more long-term sustainability. 

But opinions vary on lab-grown vs. mined diamonds. Some experts claim that mined diamonds are better for the environment than synthetic ones because producing lab diamonds is a carbon-intensive process. Learning about the ethical issues in diamonds can help you determine whether you want a lab-grown or mined diamond.

Are lab-grown pink diamonds worth buying?

This is a question everyone needs to answer for themselves. The cost difference between mined pink diamonds and lab-grown diamonds is significant, making lab-grown pink diamonds a great alternative. Lab-grown diamonds are also just as durable as mined diamonds (10 on the Mohs scale). But be aware that lab-grown diamonds don’t maintain their value like natural diamonds do.

Do lab-grown pink diamonds hold their value?

A lab-grown pink diamond, just like any lab-grown diamond, doesn’t have inherent value and has no resale value. The fluctuation in the price of lab-grown diamonds depends on supply and demand, and the current price of mined diamonds. 

In the past, lab-grown diamonds cost 20% more than mined diamonds, but now lab-grown diamonds cost 40% to 50% less than mined diamonds. All this to say, the value of lab-grown diamonds fluctuates based on the market. 

Understanding the value difference of lab-grown vs. natural diamonds can help you determine what type of diamond to buy.

How to choose lab-grown pink diamond engagement rings

When you’re shopping for a pink diamond engagement ring, there are a few factors to consider, such as the quality, price, and color.

1. Color intensity

The main reason to choose a pink diamond is for its color. And that’s why color intensity and secondary shades should be the biggest factors when searching for a diamond. Look at various pink stones to determine what type of color catches your eye (and heart) the most.

2. Diamond shape

The shape of your diamond impacts the aesthetic. A round stone is classic, while radiant cuts, princess cuts, and cushion cuts add a modern touch. The shape you choose is totally up to your personal preference, and can enhance the character of your ring.

3. Precious metal

The precious metal you choose plays a role in the appearance and price of the ring. White gold, yellow gold, platinum, and rose gold all pair nicely with a pink diamond. 14K and 18K gold is durable enough for everyday wear, and costs less than platinum.

4. Reliable vendor

Where you buy your lab-grown pink diamond matters. You want to shop with a vendor that has a reliable reputation, well-crafted jewelry, and customer-friendly services. For pink lab-created diamonds, we recommend James Allen as they have one of the largest selection of pink lab-grown diamond rings.

5. Price and carat weight

Consider your budget and how much you want to spend on your engagement ring. Keep in mind that color is the most important aspect of a pink diamond, above carat weight and cut quality. A beautiful, eye-catching color in a lower carat weight is more impressive than a large, dull pink diamond. 

6. Setting style

From vintage settings to halo designs, opt for a ring that suits your style and personality. Because pink diamonds are so stunning, consider a solitaire ring, or aim for one that subtly highlights the diamond, such as a halo or pavé band.

What are the different shades of lab-grown pink diamonds?

Lab-grown pink diamonds range from faint pink to deep, rich pink, and sometimes include secondary hues such as purple, orange, and brown. Intensity of color can vary significantly. Brown and orange undertones tend to be viewed as more negative, while purple is considered a positive enhancement. The price of a purplish pink diamond can be five or six times as much as an orangey pink stone.

Pink diamonds are ranked for their color on the following scale: 

  • Faint
  • Very light
  • Light
  • Fancy light
  • Fancy
  • Fancy intense
  • Fancy vivid
  • Fancy deep or Fancy dark
Color intensity of Pink lab-grown diamonds

These are general categories, but each diamond’s color is unique. In general, the deeper and richer the color, the more valuable and pricier it is.

Dark pink lab-grown diamonds

Dark pink lab-grown diamonds have a rich, deep hue. They might also have purple undertone that enhances their color. 

Rose gold lab-grown diamonds

Rose gold lab-grown diamonds have a pink color with an orangey yellow hue.

Blush pink lab-grown diamonds

Blush pink lab-grown diamonds are the most traditional pink diamonds. They have a very pink, cheery hue.

What are the other colors of lab-grown diamonds?

Lab-grown diamonds come in a variety of colors including yellow lab-grown diamonds, blue lab-grown diamonds, and green lab-grown diamonds. The laboratory process is slightly different for each color, helping to form its permanent color. Price depends on the richness of the hue and the carat weight, though pink lab-grown diamonds tend to be higher priced than green and blue diamonds.

Lab-grown pink diamonds vs. pink sapphires

Pink sapphires are gemstones of the corundum family while lab-grown pink diamonds are made of carbon. Sapphires are far less expensive than pink diamonds and they tend to be more simplistic in their color, such as very pink or purpley pink. Pink sapphires also tend to not have as much depth or richness of color as pink diamonds.
