In which colors are laboratory-created diamonds available?
For those who appreciate elegant colored gemstones, diamonds created using the HPHT process are generally yellow, yellow-orange, or yellow-brown. Most of them are Type IIB, which is rare for natural diamonds. Adding boron in the growth process forms blue diamond’s created in the laboratory. Man-made pink and red diamonds, but less common, can be produced by subjecting the crystal after growth to heat treatment processes involving heating, radiation and heating. Colorless HPHT synthetic diamonds are very difficult to create as nitrogen must be excluded from the growth process, so it is necessary to modify the growing conditions and equipment.
CVD lab grown diamonds New Zealand are usually grayish or brown in color. Adding a small amount of boron or nitrogen to the chamber will create diamonds that are yellow, pink-orange, or blue. Colorless crystals are easier to produce with this method, but they take longer to grow. It is believed that many of the available laboratory-created colorless CVD diamonds were originally brown crystals discolored by HPHT annealing. CVD synthetic diamonds are most commonly Type IIA. Lab-created fancy colored diamonds are sold at comparatively reasonable prices compared to their natural fancy colored counterparts.
Are man-made diamonds the same as synthetic diamonds?
There is undoubtedly some confusion between man-made diamonds and synthetic diamonds, but the simple answer to this question is NO, they are NOT the same. Synthetic diamonds do not have the same physical properties as natural diamonds; while in comparison artificial diamonds have the same material properties and elements as natural diamonds, only that they come from the laboratory and not from the earth. Lab-created diamonds are man-made diamonds that consist of real carbon atoms arranged in the characteristic crystal structure of diamond in the same way that natural diamonds are formed. Imitations of diamonds, such as cubic zirconia are similar to diamonds. They resemble the appearance and properties of natural diamonds, but have a different chemical structure from real diamonds.
A replica diamond can be man-made, natural, or in some cases a combination of them. Although their material properties are very different from those of natural or man-made diamonds, stimulants have certain desired characteristics that ideally lend themselves to imitation. Qualified gemologists are able to distinguish natural and synthetic diamonds from simulated diamonds, primarily by visual inspection.
Are man-made diamonds expensive?
Due to the high cost of technology and the high energy consumption required to create man-made diamonds, these gems come at a high price. A synthetic diamond is approximately 30% -50% cheaper than a mined natural diamond of equivalent clarity, cut, color and size. While lab-created diamonds are becoming popular with those who have concerns about the ethical credentials of some aspects of diamond mining or are on a budget, for many this price differential is not a sufficient incentive to choose them over diamonds. This is particularly true for those who want to purchase a diamond jewelry item as an investment.
If price is a criterion for choosing a gemstone, then one of the biggest advantages of buying a man-made diamond is that it will be a less expensive option.
