Why CVD ?

CVD Diamonds can be termed as a lost identical twin of natural diamonds. They have exact properties, shine, atomic structure, and looks but are a little more empathetic towards the environment and people. CVD diamond wafers give you the flexibility of creating a diamond of different shapes, sizes, colours, and numbers. Our expertise is the best in the field of diamonds

CVD Diamonds:
Everything You Need to Know

CVD diamonds over natural diamonds

CVD Diamonds are atomically identical and are composed of pure crystalline carbon. They grow much faster as compared to natural diamonds. These lab-grown diamonds are accredited to the same standard of 4C's grading as natural diamonds, i.e., Cut, Color, Clarity, and Carat, and are ranked likewise. They comparatively are cost and time effective and saves mining and extraction costs making them human and environmentally kind.

CVD diamonds over other Lab-grown Diamonds

All CVD diamonds are lab-grown diamonds, but not all lab-grown diamonds are CVD diamonds. Synthetic diamonds come with different names today; HPHT, CVD, detonation synthesis, and ultrasound. Chemical Vapour Deposition is the most effective method to create these human-made diamonds. CVD diamonds, unlike other laboratory cultivated diamonds, are a more efficient method and have the exact composition of natural diamonds.

CVD diamonds and their Applications

CVD diamonds are a great replacement for natural diamonds. They are the best options in jewelry nowadays as it is ethically kind towards people and the environment. People want to keep their foundation of love not by harming anyone but by making the best from the technology. They are applicable in all kinds of jewelry of various shapes, sizes, and colours. Diamonds, no more a surprise, are the hardest materials, chemically inert, and have high thermal conductivity.

There have been replications in skills; however, the technology for growing actual diamonds in the laboratory is relatively new. Here are the answers to frequently asked questions about lab-grown diamonds.

Chemical Vapour Deposition (CVD) is a process used to develop lab grown CVD diamonds.

Chemical vapor deposition (CVD) is a vacuum deposition method used to produce high quality, high-performance, solid materials. The process is often used in the semiconductor industry to produce thin films.

Chemical vapor deposition (CVD) is a technology used for forming solid powders in the gas phase or depositing films on substrates from precursors in the gas phase. Many precursors are liquids or solids under ordinary conditions, and they are first vaporized for use in CVD.

Lab-grown diamonds are cultivated and natural ingredients are placed in an environment created to duplicate nature. As soon as combination of chemical and environmental factors is created, diamond starts growing in the lab. These man-made diamonds have the same physical and chemical properties that are identical to natural.

You can identify CVD diamonds fairly simply. They have a unique strain pattern that doesn't resemble that of natural diamonds and strong red fluorescence. In addition, they lack the typical “Cape Line” at 415 nm on their absorption spectrum. Instead, they present a strong line at 737 nm.

Unlike diamond simulants such as CZ or Moissanite, lab-created diamonds will test positive when using a diamond tester.

Depending on the color and size, it can take between 60-120 days to create a diamond in the laboratory.The CVD process allows carbon atoms to attach to the seed diamond layer by layer. This produces a beautiful, genuine diamond. But the process is a slow one — generally moving at a rate of 0.1-10 microns per hour, for larger surfaces (smaller surfaces grow at slower rates). Estimates vary, but it is generally considered to take about a month to grow a 1ct CVD diamond.

Flawless :

Since CVD diamonds are made in a lab under extremely controlled conditions, they are flawless. They do not have any imperfections.

Conflict Free :

CVD diamonds are devoid of any ethical or ecological issues. These diamonds are guilt-free because they are a comparatively sustainable choice.

Quality :

Lab-grown CVD diamonds have a rigorous quality check process in place and these diamonds are graded just like natural diamonds.

Affordability :

One of the prime reasons why CVD diamonds are sought after is affordability. They are 25 to 30 percent cheaper than natural diamonds.

Not only are lab diamonds as durable as natural stones, but they're also chemically, optically, thermally, and visually identical to earth-mined diamonds. Lab diamonds really do last forever, and there's nothing that will dull the shine or interfere with the brilliance of synthetic diamonds.

Yes! Just like a mined diamond, laboratory grown diamonds can be insured. In fact, by choosing a lab-grown diamond, you'll not only save money on the diamond itself, but you'll also save money on the annual premium of the insurance policy due to the lower overall cost of the insurable piece.

Lab -Grown Diamonds come with 100% Lifetime Exchange and an 80% Buyback at the prevailing rate.

All Lab Grown Diamonds are certified by IGI, GIA, GCAL , or HRD. They are also Laser inscribed with their certificate number.

Yes. GIA has been grading laboratory-grown diamonds since 2007.

Yes, each certified BLGD Created Diamond has a unique ID inscribed on the diamond itself. This information is detailed in your certificate so you can always identify your diamond with the help of a jeweler.

Yes, BLGD produces diamonds in a variety of modern patented and traditional shapes such as round, cushion, princess, ovals, pear, marquise emerald and more.

Yes. BLGD is headquartered in New York and has distribution links across North America, Europe, Asia, Australia and Africa. This lets us create a broad range of jewelry for a wider, global and curious audience and incites demand for diamonds all over the world.

Lab diamonds are as strong and as hard as natural diamonds, both scoring a 10 on the Mohs scale of hardness.
