ラボラトリー・グロウン・ダイヤモンドとは？

Laboratory grown diamonds are 100% identical to mined diamonds. They are just grown from a ‘seed’ in a laboratory, building layer upon layer using HPHT (high pressure high temperature) or CVD (chemical vapor deposition) to replicate the natural process over several days or weeks, rather than in the earth over millions of years. Aside from their origin, they are exactly the same.

Laboratory grown diamonds offer the freedom to explore more breadth of jewelry in terms of sizes, shapes and settings than ever before, more easily. Swarovski is proud to offer modern, inspired designs with premium quality diamonds, meaning you get larger and higher quality stones tailored to every price point.

Laboratory grown diamonds are made using an innovative process that flawlessly replicates nature, resulting in a laboratory grown diamond that is indistinguishable from a mined diamond in all chemical, physical, and optical attributes. There are two ways to replicate the diamond formation process: HPHT (high pressure high temperature) and CVD (chemical vapor deposition).
The technology is as brilliant as the laboratory grown diamonds themselves. In both cases, a tiny diamond seed is nurtured with carbon atoms under laboratory conditions of intense heat and pressure, forming layer by layer. Each laboratory grown diamond forms in its own way, with one-of-a-kind inclusions and unique growth patterns.

Yes, laboratory created diamonds are 100% diamonds. They are identical to mined diamonds possessing the same chemical composition, hardness, brilliance and fire. Both are 100% carbon.  One is born in a laboratory, the other one in nature - just as a greenhouse-grown orchid is identical to one found in nature. The only difference is their origin.

Laboratory grown diamonds are 100% the same as a mined diamond in all optical, chemical and physical aspects. Only the diamond’s origin – coming from the earth or coming from a laboratory – is different. This difference can only be identified with sophisticated laboratory equipment. Laboratory grown diamonds processed in Swarovski Created Diamonds jewelry can be identified by a laser engraving on all laboratory grown diamonds 0.25 ct and larger.

No, a jeweler cannot tell the difference between a laboratory grown diamond and a mined diamond with the naked eye or using traditional jeweler’s equipment. Sophisticated instruments are required from a Gemological Institute like IGI to find out if a diamond is laboratory grown, or grown in the earth.

No, they are identical to mined diamonds possessing the same chemical composition, hardness, brilliance and fire. Both are 100% carbon.
Moissanite, while also created in a laboratory, is a silicon carbide engineered to give the illusion of similarity to diamonds, but is compositionally and visually quite different.

Diamond simulants such as Cubic Zirconia and Moissanite are not diamonds in any way, but gemstones manufactured to look like diamonds which are physically, visually and compositionally very different.

No, Cubic Zirconia is not the same as laboratory grown diamonds. Cubic Zirconia is a diamond simulant and is physically, visually and compositionally very different to a diamond. Conversely, laboratory grown diamonds are 100% identical to their mined counterparts, but the way they originate.
