Man Made Diamonds also described as Synthetic Diamonds, Cultured Diamonds, Lab Created Diamonds or Lab Grown Diamonds are real diamonds that are optically, physically, atomically and chemically identical to a natural diamond. These diamonds are grown in a lab environment that replicates the earth’s natural growing process. Lab Grown Man Made Diamonds are identical to earth mined diamonds and are solid, pure carbon diamonds. MiaDonna’s® line of Man Made Diamonds will absolutely test positive on any jewelers diamond tester and all come with either EGLUSA, IGI or GIA certified grading reports.


Compare MiaDonna® Man Made Diamonds to Natural Diamonds.

MiaDonna® Man Made Diamonds are type IIa diamonds. Less than 2% of all the natural diamonds harvested in the world are pure enough to be labeled type IIa diamonds.

$$ Pricing Man Made Diamonds $$


 White Man Made Diamonds are in very limited supply. The process used to create a white diamond is also the most time consuming and temperamental thus, MiaDonna® type IIa, White Man Made Diamonds are priced 12% to 17% cheaper than mined diamonds offered from larger online diamond retailers like BlueNile.




Both Orange and Yellow Man Made Diamonds are being produced in large quantities. Yellow and Yellow-Orange diamonds grow the fastest, typically taking 5 to 6 days in the growth cell and are priced 25% cheaper than their mined diamond equivalent. 



Natural blue diamonds are incredibly rare in nature and can sell for anywhere between $200,000 to $500,000 per carat. A Blue Man Made Diamond costs about 10% of what a mined blue diamond retails for. 




Natural pink diamonds are the rarest in the world. The vast majority of pink diamonds come from mines in Australia. The extreme limited availability puts the cost of these mined pink diamonds between $56,000 to $150,000 per carat. A treated Pink Man Made Diamond will cost between $5,000 and $10,000 per carat. The price per carat weighs heavily on the color of the diamond itself. On average, a Pink Man Made Diamond is about 20% the cost of a mined pink diamond.

How to grow a Man Made Diamond

MiaDonna’s® Man Made Diamonds are created using one of two different growing techniques that both result in a pure carbon diamond when complete.

High Pressure High Temperature (HPHT) Diamond Growing Process

The growth cell itself contains all the elements needed to grow a diamond, including a tiny diamond seed, highly refined graphite and a catalyst consisting of a mixture of metals and powders. The growth cell is placed in the center of the HPHT machine. Very consistent temperatures reaching 1,300 degrees Celsius and over 50,000 atmospheres of pressure are applied to the growth cell. The catalysts inside the growth cell are the first to react to the added heat and pressure by changing from solid to molten form.

The catalyst molten solution now causes the graphite (carbon) also in the growth cell to dissolve. Once all the required conditions within the growth cell have been met, the cooling process begins. This highly controlled cooling process takes place over many days and allows the carbon atoms to build up on top of the diamond seed that was part of the original growth cell mixture. The growth cell is removed from the HPHT machine once the growth cycle is complete. The new rough diamond is cleaned and now ready for final cutting and polishing.
The entire HPHT growing process requires an incredibly controlled environment to produce a gem quality diamond. Any shift or change during growth can cause the diamond itself to stop growing or can cause any additional growth to be heavily included and become unusable. Every grown diamond must go through an entire growth cycle before the machine can be opened. It is only after the HPHT machine is opened that we are able to see the finished diamond along with the color, clarity and size that was produced. Currently the Bars Press is the most effective tool used for producing gem quality diamonds. The Bars Press uses a combination of inner and outer anvils to apply hydraulic pressure to the growth cell within the unit.

 Chemical Vapor Deposition (CVD) Diamond Growing Process

Chemical Vapor Deposition or CVD environments use a small percentage of one atmosphere of pressure. Carbon based gases like methane are heated until the gases inside the environment break apart and allow the carbon atoms within the gas to separate. These tiny carbon atoms fall onto a diamond substrate and over a few days build up layers resulting in a rough diamond crystal. The majority of diamonds produced from CVD are best used for semiconductors, but there are also many gem quality CVD diamonds entering the market.

Moissanite vs. Diamond Hybrid®

Compare Charles and Colvard Moissanite side by side to the MiaDonna Diamond Hybrid®


 We get a lot of inquiries about the difference, both visually and technically, between our Diamond Hybrid® and Moissanite. For a long time Moissanite was the only diamond alternative, other than CZ, available on the market. However, with advancements in technology, comes superior diamond simulant options, such as the MiaDonna Diamond Hybrid®. While both of these products are popular diamond alternatives among eco-friendly and price conscious consumers, when compared side by side, the difference in beauty between the two products is obvious. The Diamond Hybrid® is more beautiful and realistic when compared to a natural diamond, in all of the 4C categories, than Moissanite.

Here you can visually and technically compare the Diamond Hybrid® to Moissanite.

Color:  The MiaDonna Diamond Hybrid® is guaranteed to be lab graded at a D to F in color while Moissanite is lab graded at an I to J in color.

Cut: The MiaDonna Diamond Hybrid® is cut by hand receiving ideal to excellent grades on the AGS cutting scale. Moissanite, because of its doubly refractive index, has a manipulated cut that shows more of a sunburst pattern instead of the highly faceted look you see in the Diamond Hybrid® and earth mined diamond alike.

Clarity: The MiaDonna Diamond Hybrid® will not grade internally flawless like CZ. The natural feathering that occurs within the infused diamond layer gives the Diamond Hybrid® a more realistic, desirable and natural looking diamond like brilliance. The Diamond Hybrid® consistently receives lab grades of VVS1 to VS2. Moissanite is lab graded at an average of VS1 to VS2.

Internal Crystal Structure: The MiaDonna Diamond Hybrid® has a face-centered-cubic, singly refractive internal structure as do natural diamonds giving the Diamond Hybrid® the ability to reflect light in the same manor as their natural cousins. Moissanite has a hexagonal-doubly-refractive index which gives a blurred or duplicated look called birefringence, a problem that splits light within the crystal giving it a blurry or fuzzy appearance, especially noticeable when placed next to a natural diamond.

Index of Refraction: Analysis shows the MiaDonna Diamond Hybrid® has an index of refraction of 2.24 giving it a tested index closer to a natural diamond’s 2.42 than any other simulant available. Moissanite, which is synthetic silicon carbide, has an index of refraction of 2.67 and makes claims that it outshines a diamond. However, just as is the case with CZ, which has and index of refraction of 2.15 the visual appearance to the naked eye will not recognize the difference in these numbers. Moissanite will appear shiny and CZ will appear glassy when compared visually to a natural diamond.

Customer Testimonial:

“I received my ring last week! Since it is a gift for our anniversary next week, my husband only let me look at it and try it on for one evening. He has since hidden it, and I have been looking for the ring so I can admire and wear it whenever he’s not around. No luck finding the hiding spot yet. :) I would really like to thank you both for all your help and professional advice in the decision making process! The ring is absolutely gorgeous!! …I am very pleased with MiaDonna! I am looking forward to purchasing my next ring! ;)

Miley Cyrus Engagement Ring from Liam Hemsworth

















 Miley Cyrus certainly has a lot to celebrate. On Wednesday (June 6), the former “Hannah Montana” star announced that she will be walking down the aisle with her boyfriend of three years, Liam Hemsworth.

 The two met on the set of their 2009 flick “The Last Song” and have been dating on-and-off ever since. Earlier this year, the couple denied engagement rumors after Cyrus was spotted with what looked to be an engagement ring. But now, they are ready to make it official.

After telling People magazine that she “is so happy to be engaged,” Cyrus took to Twitter to thank her fans for their overwhelming outpouring of well-wishes. “thank you for all the love today :) I’m happy to share this news with you all,” Cyrus wrote. “I feel like all my dreams are coming true. ❤ have a great day”

 Now adorning Cyrus’ left hand is a stunning 3.5-carat sparkler, which Hemsworth had a hand in creating.The “Hunger Games” star teamed up with celebrity jeweler Neil Lane, who told People that Hemsworth wanted “something really beautiful and romantic” for his soon-to-be bride. The ring, which has a vintage feel, was handcrafted in 18-karat gold and is garnished with diamond floral patterns. Yet, it’s the antique center stone that truly makes this a unique and beautiful engagement ring.


 “It was hand-cut around 1880 or 1890 and it’s unique and in its original form,” Lane said. “At that time no two diamonds were alike, as they were all hand-cut, so it’s fascinating to look at because it hasn’t been re-cut to look contemporary over the years. I find that really romantic.”

 And, according to Lane, so did Hemsworth: “It’s everything he was looking for.” Hemsworth wasted no time in giving Cyrus the ring, which was completed last week, just in time for him to propose to Cyrus on May 31.
