HPHT Lab Grown Diamond DEF Color VVS VS Emerald cut Loose gemstones Wholesale from China Suppliers & Manufacturer PICTURES HD Video:  What's Synthetic diamond? A synthetic diamond (also known as a laboratory-grown diamond, a cultured diamond, or a cultivated diamond) is a diamond produced by a controlled process, as contrasted with a natural diamond created by geological processes or an imitation diamond made of non-diamond material that appears similar to a diamond. Synthetic diamond is also widely known as HPHT diamond or CVD diamond, after the two common production methods (referring to the high-pressure high-temperature and chemical vapor deposition crystal formation methods, respectively). While the term synthetic may sometimes be associated by consumers with imitation products, synthetic diamonds are made of the same material as natural diamonds—pure carbon, crystallized in an isotropic 3D form. WHAT IS THE DIFFERENCE BETWEEN HPHT AND CVD? When comparing CVD vs HPHT diamonds, there is absolutely no difference other than the process used to create them. You will not be able to tell the difference between HPHT vs CVD diamonds. Both methods are capable of producing the full range and quality of real diamonds that are optically, chemically, and physically identical to earth-grown diamonds. We could dive deep into the technicalities of each method, detailing all the difference in the production process, but we believe it’s a waste of time at best and confuses and misleads people at worst. Instead, we prefer to provide you with practical and easy to follow reliable advice. As you are aware, each and every one of our lab-grown diamonds are industry certified by leading certifiers, therefore when choosing your diamond, solely focus on trying and go for as high of colour and size as your budget allows it. Additionally, when it comes to clarity, try to go for...

Lab Grown Diamond CVD HPHT Blue And Pink Color Gemstones Wholesale from China Suppliers & Manufacturer Lab Grown Pink Diamonds - are these real diamonds? Extremely high quality, real diamonds are now being grown in various labs around the world. True Pink lab grown diamonds are rare as it's hard to do Pinks even in the lab, but our lab grown Pink diamonds are the real deal - real, 100% Pink Diamonds. These will test positive as diamond in *any* diamond test - because they are 100% real pink diamonds, simply grown above the Earth's surface instead of below the Earth's surface. Of interest, there are two ways to grow lab diamonds: 1) replicating the high pressure temperature that occurs under the Earth (known as HPHT) and 2)replicating the extremely low pressure of outer space in a lab (there a lot of diamonds in outer space btw!) - this is known as CVD. Most lab grown diamonds are white or yellow or blue. Our lab grown pink diamonds are rare even in the lab grown diamond world, and are 100% real diamond. pink diamonds can be grown using both of the above processes, as both produce real diamond. Our pink lab diamonds are graded at independent diamond grading labs like any other mined diamond. The difference is they were formed in a lab rather than under the Earth's surface. Their pink color is naturally part of the diamond itself, and comes from the secondary step of exposing it to additional high pressure. These are not 'coated' pink diamonds, the color is atomically part of each diamond itself. Where can I buy a real lab grown Pink Diamond? As noted, true lab grown pink diamonds are hard to come by but we specialize in Pink Diamonds and have a number of...

Loose Natural Genuine Carnelian Red Color Bullet shaped 5x4mm Smooth cabochon gemstones Wholesale at factory direct price from China Suppliers and manufacturers. Picture What's Carnelian Red Color Gemstones? Carnelian is a variety of chalcedony and is a microcrystalline quartz. As a chalcedony, carnelian is formed from the intergrowth of two silica minerals with differing crystal structures: quartz and moganite. Carnelian appears in a vibrant range of fire-orange reds to brown-reds and has a dull, waxy luster (as opposed to the vitreous quality of crystal quartzes such as amethyst). The reddish tints in the translucent stone are due to one of its ingredients: iron oxide. Carnelian can be confused with jasper, which is usually considered a chalcedony. Carnelian is most commonly found in India, Brazil, Siberia and Germany. Most carnelian gemstones are dyed and heat-treated to achieve additional color variations. Carnelian is the birthstone for the zodiac sign of Virgo (August 23 - September 22). For most cultures, from the 15th to the 20th century, carnelian was one of four birthstones for August. In 1912, the United States adopted peridot as the August birthstone, however in 2013, Britain recognized carnelian as a secondary birthstone after ruby. Where to buy Carnelian Red Color Gemstones?

Loose Natural Semi precious Genuine Chrome Diopside Green Color Round faceted 1.50mm gemstones Wholesale at factory direct price from China Suppliers and manufacturers. Picture What's Semi precious Chrome Diopside Green Color stones? Gemstone quality diopside is found in two forms: black star diopside and chrome diopside (which includes chromium, giving it a rich green color). At 5.5–6.5 on the Mohs scale, chrome diopside is relatively soft to scratch. Due to the deep green color of the gem, they are sometimes referred to as Siberian emeralds, although they are on a mineralogical level completely unrelated, emerald being a precious stone and diopside being a semi-precious stone.[9] Chrome diopside is colored by chromium, the same element that gives emerald its rich green color. This beautiful intense green color and its high refraction give the gem great brilliance and life. Diopside is found in many areas around the world and in different colors, however, gem quality chrome diopside is mined in the mountains of Siberia, Russia near diamond bearing kimberlite pipes. In 1988, this “new” green gem from Russia started to be seen in the jewelry industry and is sometimes referred to as “Russian Emerald” in the trade. The resemblance of its color to tsavorite garnet, chrome tourmaline, and emerald made it a standout, and the more affordable price made it popular.
