The crucial role of Diamond Laboratries

The Crucial Role of Diamond Laboratories: an Overview

Purchasing expensive diamonds certainly necessitates the customer making an informed and intelligent investment decision. Hence, clear knowledge about the authenticity certification of diamonds is quite important.

Diamond laboratories play an enormously significant role in the development, quality management, and certification of these dazzling gemstones. There is a wide variety of synthetic or lab-designed diamonds available in the market with the three broad categories including fancy and colourless diamonds, industrial diamonds, and memorial diamonds. There are specific gemmological laboratories that specialize in the technology of gemstone treatment and issue diamond certification or grading reports.

Why seek diamond certification by reputable diamond laboratories?
Whether you are buying loose diamonds or diamond jewellery, it is essential that you make an informed and smart investment decision by verifying the authentication of the gem. The diamond certificate is a manufacturer and seller’s guarantee that you are procuring quality and authentic diamonds. A Diamond report ascertains that the gemstone has been graded and examined by a panel of expert independent diamond graders. A diamond certificate highlights the following characteristics of the stone:

• Certificate number
• Attestation of authenticity
• Detection of enhancement and treatment methods
• Individual characteristics of four Cs – Cut, Clarity, Colour and Carat
• Millimetre and fluorescence measurements
• Proportion and clarity outlined in plotted diagram
• Comments of grader

Though there is quite a flurry of gemmological labs around the world, jewellers in the competitive diamond industry prefer to associate with a select number of internationally renowned gemmological laboratories employing stringent diamond grading measures. These laboratories are Gemmological Institute of America (GIA), American Gem Society Laboratories (AGS), Hoge Raad Voor Diamant (HRD), and International Gemmological Institute (IGI).

Diverse diamond creation techniques at diamond laboratories:
Commonly known as cultured or laboratory-created diamonds, these immaculate gems come in a marvellously varied colour palette – ranging from clear white brilliance, yellow, lovely pink, to blue. Unique in their perfection, these diamonds are extremely popular among the buyers. The two most commonly employed diamond production methods are –

• High-Pressure High-Temperature (HPHT) – Just like the name suggests this system deploys high temperature and high pressure to considerably improve the clarity and translucence of the gem.
• Chemical Vapour Deposition (CVD) – Diamonds are created from hydrocarbon gas mixture incorporating carbon atom deposition.
To understand the science behind every exceptional sparkling diamond, a closer look at its creation process is vital. Always make an informed purchase decision.
