Additionally, a lot of young couples are increasingly selecting lab-grown diamonds for their engagement rings because it is a practical and environmentally friendly choice.

Moreover, nothing can be more unique than a diamond created from your own essence, These days, many dealers provide special services to meet people’s wishes. Sunny Eden™, for example, makes lab-grown diamonds from your hair. A lab-grown diamond engagement ring created from the material containing both person’s DNA is a truly unique and personalized choice for couples. It is also a witness to every unique love story.

How to choose affordable diamond engagement rings in the market

Unless you’re prepared to travel halfway across the world (to a place like France or Switzerland) in search of a lifetime deal in auction houses, a natural blue diamond is not a gemstone you can buy on a budget. However, in recent years, lab-grown blue diamonds have offered every couple the chance at having the regal sparkle of an affordable blue diamond ring to grace their engagement.

Although some people might think that man-made diamonds are inferior compared to natural ones, the opposite couldn’t be more true. A blue lab-grown engagement ring matches its mined counterpart neck-on-neck in just about every respect. 

If you want a diamond stone that ticks all the boxes of an exotic gemstone except for a mammoth price tag, then lab-grown diamonds are your best bet. 

However, lab-made blue diamonds are not all created equal. There are various techniques for growing lab diamonds, each with its unique attributes. Sunny Eden™ grows deep-glowing blue diamonds from human hair. 

The techniques for creating lab diamonds in general can be roughly grouped into two growing techniques: high pressure-high temperature (HPHT) and chemical vapor decomposition (CVD).

The difference between lab-grown diamonds from hair (HPHT) and CVD lab diamonds

HPHT techniques replicate the high-pressure, high-temperature environment in the earth’s crust where diamonds naturally occur. Sunny Eden™ takes the carbon from a customer’s hair and processes it in an HPHT setup to transform it into a diamond within a few months.

In chemical vapor decomposition or CVD, a vapor of chemicals is used to crystallize a shard of carbon into a diamond under extreme temperatures. However, in many cases, HPHT processes are used to improve clarity and color in CVD diamonds. CVD diamonds usually come up a bit short in certain regards compared to HPHT diamonds. On the other hand, most dealers provide HPHT and CVD diamonds for almost the same price. In this way, HPHT diamonds are better choices: the same price, and higher quality.

Meaningful, personalized, and affordable blue diamond engagement rings from hair

Another key advantage of choosing engagement rings with HPHT diamonds made from the hair of loved ones is the wider range of customization options.


At Sunny Eden™, you can sketch your own design and then watch as the designers bring your dreams to life. Not only can you choose any desired color shade, but you can also specify many other aspects of diamond made from hair - the shape, cuts, and lots more. Whatever you need in an engagement ring, rest assured Sunny Eden™’s experts will make it a reality. 

Other things you need to know about blue lab-grown diamond engagement rings

Can we use blue diamonds as the center stone of engagement rings?

Yes. Blue diamonds are among the rarest color diamonds. For centuries, they’ve been associated with royalty, high status, and good luck.  But the enormous price tags for naturally mined blue diamonds put them beyond the reach of average couples. Lab-created blue diamond engagement rings are modern, prestigious, and sensational. In addition to this, lab-grown blue diamonds offer the equivalent of natural stones at significantly lower prices.


How much does a blue lab-grown diamond engagement ring from hair cost?

Like mined diamonds, the cost of lab-grown diamonds from hair is determined by the 4C’s - clarity, cut, color, and carat. On average, 1 carat of a lab-made blue diamond from hair costs at least $5000. When it comes to cut and shape, round cuts usually generate more brilliance and sparkle and are therefore more expensive. Princess-cut blue diamond engagement rings are among some of the most popular choices. The price of the ring setting starts from $750, different ring styles have different prices.

Sunny Eden™‘s diamonds are made from the hair of their customers. The trace elements in each person’s hair vary slightly, which creates a unique color for each blue diamond. Therefore, the price of Sunny Eden™’s diamonds is not affected by the color intensity.
