Fancy Cut Lab Diamonds Description

 

Lab diamonds are real diamonds. Carbon is the main element of natural and laboratory-grown diamonds. The chemical and physical properties of synthetic diamonds are same as natural diamonds in terms of hardness, thermal conductivity, and strength. HTHP and CVD are the two main methods for making laboratory-grown diamonds. High temperature and high pressure method (HTHP) uses graphite as raw material. HPHT diamonds are manufactured at a pressure of 5-6 GPA (approximately the pressure produced by a commercial jet landing on a human fingertip) and a temperature of 1300-1600°C. CVD diamonds come from various gases, such as methane. They are stored in a vacuum chamber, which decomposes the molecules of the gas, and then these molecules gather on the pre-existing diamond seeds.

 

Round cut is the most common cut. Fancy shaped lab diamond, also known as gardener cut diamond, refers to diamonds other than standard round diamonds. The common fancy shape lab diamonds include pear shaped, marquise shaped, princess, radiant, emerald cut, heart, oval shape, etc.

 

Oval cut diamond is based on the traditional structure of round brilliant cut. Oval diamond has the same beautiful brilliant color as round diamond. Oval diamond because of its length so as to highlight the slender fingers of women, so it is also a very popular diamond shape. The perfect golden ratio for an oval diamond is 1.5:1, which means that the length is about 1.5 times the width. If the aspect ratio is greater than 1.5, a dark area will appear in the middle of the diamond, which is called the bow effect. This kind of diamond is not ideal. If the ratio is less than 1.5, the diamond looks like a deformed round diamond. For cutting, the best depth ratio is 59% - 63%.

Lab Diamonds Introduction

 

Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The Lab Grown Diamonds are produced in the laboratory, usually in a few weeks. The chemical difference between the two is same.

So how do you distinguish between Lab Grown Diamonds and natural diamonds?

There is no obvious difference between the Lab Grown Diamonds and natural diamonds. Even professional gemologists need special equipment to identify them. By zooming in, professionals will be able to discern subtle contrasts in diamond inclusions grown and mined in the laboratory.
