FAQ - Created Dismonds

General

Created diamonds are diamonds that are grown under laboratory conditions. These laboratories simulate the environment that is beneath the earth’s surface when diamonds form by having similar temperature and pressure conditions. Carbon, in the form of graphite, is present

Created diamonds have the same physical, chemical and optical properties of mined diamonds. Both are grown within a matter of days; however mined
diamonds take millions of years to be found and extracted from the earth. The rough Created diamond undergoes the same processes of cutting and
polishing as a mined diamond.
Yes. They share the exact same chemical, physical, and optical properties of earth grown diamonds. Created diamonds, like those produced 100s of kilometers below earth’s surface, have unequaled hardness, fire, brilliance, and scintillation. The only difference between Created diamonds and earth grown diamonds is where they are grown.
These terms are all synonyms for one another. Each of these terms is considered correct terminology for laboratory grown diamonds; they each insinuate that the diamond has been grown in a laboratory in a prepared medium of temperature and pressure.
Created. Created diamonds and synthetic diamonds are not the same thing and it is very important to understand the difference between the two. 
In order to understand the answer to this question, you must first have a clear understanding of what the terms “synthetic” and “synthesis” actually mean. The primary meaning of the term “synthetic” is “something resulting from synthesis” or something that is “made by chemical synthesis”. “Synthesis” in turn refers to a “combination of components to form a connected whole” or “the production of chemical compounds by reaction from simpler materials”. In order for something to be described as “synthetic,” it must result from or be made by “synthesis”. 
When growing Created diamonds, no synthesis takes place; there is no combination or reaction between different materials. While some precious stones are composed of a combination of different elements, such as Ruby, Diamond is composed of only carbon. For this reason, it is argued that referring to a laboratory grown diamond as “synthetic” is both misleading and factually incorrect. The term “Created” is defined in the Merriam – Webster online dictionary as “grown within a prepared medium”. Created diamonds are grown in a prepared medium of temperature and pressure that mimics the conditions in which diamonds form deep below the earth’s surface.
“Mi-Ya Diamond does not make gemstones; we make environments in which crystals grow naturally.” 
They’re real. Once the required combination of chemical and environmental factors has been created, the crystals grow over the course of a year; the exact length of time depends on the specific gemstone being grown. What this means is that our quality diamonds and gemstones are developed with the exact same physical, chemical, and optical properties that are found in nature.
Mi-Ya Diamond Created Diamonds, grown under laboratory conditions, have the same exact characteristics as earth grown diamonds; Mi-Ya Diamond Created Diamonds have the same unequaled hardness, fire, brilliance and scintillation as those produced by nature. The color of Mi-Ya Diamond’s is also created in the same exact fashion as nature intended – high nitrogen content produces yellow, boron added produces blue, and nitrogen-minimized produces white. 
The only difference is where they are grown. Mi-Ya Diamond Created Diamonds consists of the same pure carbon crystal structure as a diamond grown in nature and they are polished in the same way as natural diamonds.
Mi-Ya Diamond’s are true, pure diamonds that are grown above ground instead of underneath it. By recreating the conditions that are present under the earth (very high temperature, very high pressure), diamonds can be ‘grown’ in a laboratory.  It is sometimes difficult to believe that diamonds can now be produced in a laboratory but with today’s technology it is the reality. While Industrial diamonds (extremely small crystals) have been available for many years.
Mi-Ya Diamond’s are pure diamond, and rate 10 or 10+ on the Mohs scale (https://en.wikipedia.org/wiki/Mohs_scale_of_mineral_hardness). The 10+ aspect refers to previous findings by the GIA and other studies suggesting that lab-grown diamonds are slightly harder and less brittle than natural diamonds. It is inferred that this is a result of ideal nitrogen dispersion in lab-diamonds, and a more perfect crystal structure. For additional details on this, please see  Mi-Ya Diamond vs. natural diamond comparison page.
Absolutely! Remember, Mi-Ya Diamonds are true, pure diamonds. To put it simply, let’s make a comparison to tomatoes: whether you pick a tomato from a field of wild tomatoes or pick it from a plant that is growing in a man-made greenhouse (designed for optimal growing conditions), you still have a tomato, and both cases, it is nature that is growing the tomato.  The green-house one is likely to look better, and perhaps taste better too, but they are both tomatoes. Apply this analogy to Mi-Ya Diamonds vs. mined diamonds. Mi-Ya Diamonds are made in a lab, Hence why we tend to call them “lab-grown diamonds”.
All our lab-grown diamonds are accompanied by an independent grading report from an established gem grading laboratory.  The lab reports, while varying based on which lab graded the diamond, are identical to those for a natural diamond except the origin is clearly noted as “lab grown”. 
Diamonds are made from carbon using either a High Pressure High Temperature (HPHT) or a Chemical Vapor Deposition (CVD) process.
Mi-Ya Diamond only sells real carbon diamonds with a hardness of 10. It is not a simulant (Cubic Zirconia, Moissanite, etc.) and it has all the same properties as a mined diamond
A created diamond possesses all the same properties as a mined diamond. A simulant may look like a diamond, but does not possess all the same properties as a diamond. Synthetic diamonds are commonly referred to as lab-grown diamonds, lab-created diamonds, man-made diamonds, or Created diamonds.
The speed at which diamond crystals grow depends on secret parameters inside the growth unit, that ultimately become part of the diamond and give the diamond its color. Nitrogen makes a diamond yellow and helps it grow very quickly. Boron makes a diamond blue but it grows at a much slower pace than a yellow diamond. The absence of helper elements significantly slows the growth of the white diamonds, making them the slowest to grow. The length of time that it takes to grow directly impacts the price of the product.
In general, fancy blues are about 1/10th the cost of a comparable mined blue, yellows are about 1/4th the cost of a comparable mined yellow and whites are about the same price of a mine white.
All of our certified diamonds are laser inscribed and fully disclosed as lab-grown.

Availability

You can buy online, toll-free over the phone at Mi-Ya Diamond, mail, fax or in-person.
We offer diamonds up to two carats, blue up to 1.25ct and white up to one carat. These are the upper limits; average and in-stock sizes will vary.
Diamonds can be grown in yellow, blue or white (colorless). Yellows can be further processed to create other colors.
Colorless diamonds, though the most unavailable in mined diamonds, are the most difficult to grow in a lab. The diamond must be grown with little to no nitrogen present in the resulting diamond. By limiting the amount of nitrogen, the carbon crystal growth is greatly slowed. The longer the diamond in growing, the more room for error or failure.
You can special order a diamond as long as it is within the range we can consistently produce. We also have a waiting list for certain criteria, and we will notify you once something becomes available.
All of our diamonds qualify for our lifetime trade-up offer. At any point in the future, you are able to trade in your diamond, and 100% of the price you paid will be applied toward any other diamond of greater value. It is an easy and straightforward process, and provides opportunity if your ideal size, color or shape isn’t currently available.
Pink, green, purple and other colors are available on request. 
We only offer polished diamonds, and do not sell any rough diamonds.

Jewelry

We have a wide selection of jewelry, from high-tech tension settings to eco-friendly classics as well as custom designs. Simply choose your loose diamond and pair it with your choice of jewelry. Regardless of how it is pictured, the jewelry can accommodate all colors and most shapes and sizes of our loose diamonds.
If you have a design you would like produced, we offer custom design services, and can produce your ideal piece of jewelry.
We have many diamonds available from 0.02cts and up in blue and yellow colors, with limited availability for whites. We list many of our matched pairs online, though we do have more available
All of our MI-YA DIAMOND jewelry is available in eco-friendly platinum, gold, and silver.
Each metal has it own advantages and drawbacks, and your choice is mainly a personal preference. We recommend platinum or 18kt gold for engagement rings.
Some people have allergies to nickel, which is present in some gold alloys. Platinum group metals are hypoallergenic and offer an allergy-free solution. Our jewelry is nickel-free and should not irritate even the most sensitive skin.

Technical

During growth, other elements assist the growth of the carbon lattice. These elements become trapped in the diamond, giving it color. Yellow diamonds come from nitrogen and blue comes from boron.
All of our as-grown colors (yellow, blue, white) are stable and permanent and will never fade or change color. Treated colors such as pink and green are permanent and stable under day-to-day wear, though caution should be taken when exposed to extreme temperatures such as a jewelers torch.
In most cases, no. Some yellow diamonds may exhibit weak fluorescence but, in general, neither our blues, whites nor yellows have fluorescence.
Pink, purple, red, green and other colors are produced on request, though they are not our mainstream product. The color is the result of post-growth treatment; it is an induced color. The only way to create a pink is to grow a diamond with low nitrogen, then subject it to a combination of irradiation and heat treatment (annealing).
Colors of MI-YA DIAMOND diamonds, namely, yellow and blue, are the same as corresponding colors of natural diamonds. They have the same nature, the same stability with time and when exposed to high temperatures, as with mined colored diamonds, are guaranteed to never fade or lose its color. Color of each MI-YA DIAMOND diamond is magnificent as-is, and needs no improvement.
Irradiation is used when it is necessary to improve color of unsightly brown or washed-out “cape” diamonds. However, colors of irradiated diamonds may fade or change when being set or when heated above 300 degrees Centigrade.
We do not speculate on which color is better, irradiated or natural–it’s a matter of preference and taste. The main difference that exists between irradiated diamonds and as-grown MI-YA DIAMOND diamonds is stability of color. Colors of our diamonds are stable with time and when exposed to high temperatures.
At MI-YA DIAMOND, we can apply different color treatment methods to our diamonds in order to create additional colors–pink, purple, green, red–and currently do it only upon request, since color treated diamonds are not our mainstream product.
Created diamonds are chemically, physically and optically identical to their mined counterparts. They are grown in a machine under very strict conditions, allowing for natural diamond growth. There are various methods available to identify it as lab-created rather than mined, including laser inscription, disclosure, inclusions and the use of various other equipment.

Other

Diamonds are made out of carbon, and so are all forms of life (humans, pets, plants, etc.). The carbon used to grow our diamonds is purified and highly refined, though technically it is possible to grow a diamond from carbon. It is not something we actively promote, though this can be evaluated on a case-by-case basis.
