So, we know that struggle to follow through on their quality claims – how about those rock bottom prices? When you first open a search for a round brilliant diamond on, the eye is somewhat tricked by what look like very low prices. It is incredibly difficult for customers to search for an Excellent or Ideal-Cut diamond despite the filter tools, the various labs listed have different standards for cut which means you will find GIA Good or Very Good cuts when searching for a top tier cut. Sadly, this is actually one of the better images on which range from non-existent to fuzzy and poor, to the image above – passable, but not great.ī have also been pulled up on their filter tools and search system. Similarly, they also sell diamonds with clarity grades that go right down to SI3 and I1 – these diamonds are simply not suitable for fine jewelry.Īlthough we can see from this image that the diamond isn’t a great cut, it’s not possible to truly analyse the color or clarity aspects.
do sell GIA certified diamonds and this lab represents the gold standard of diamond reports, however to sell them alongside diamonds with shady reports is not in keeping with the claims of ‘attention to quality’. This allows companies an even bigger mark up, whilst the customer is left out of pocket with a sub-par diamond. This is always a red flag for me these labs (particularly EGL) are favourites of ‘rack them and stack them’ stores (such as Zales) due to their inflated grades. offer diamonds with inferior certificates such as IGI, EGL and HRD.
Getting straight into it, the diamonds are the first place where falls down in quite a spectacular way. In my experience, do not seem to operate this way and there are various issues in their communication and customer service (more on this later). They have a vague introduction video that gives the impression of an ‘on-site’, family operation, but it would not be the first time that a company has used this clever marketing tactic to give the impression of a personable, small run company. I have used my sources and asked around about but currently very little is known about them on the jewelry circuit. However, with the bar so high for both diamond quality and customer experience, can compete with industry leaders like Blue Nile, Whiteflash, and James Allen? My detailed review will tell you everything you need to know. They promise unbeatable prices for diamonds and engagement rings together with a keen attention to quality. A CUT ABOVE Diamonds® by Whiteflash ReviewĪ post shared by the faceless diamond companies that we see springing up across the internet, appear to give a personal approach to customers, with introduction videos and a clear, user friendly website.Differences Between GIA, AGS, EGL, IGI Certification Labs.The Angular Spectrum Evaluation Tool (ASET).For more information about moissanite’s qualities, refer to our Moissanite FAQ Section. The brilliance of moissanite is unrivaled among popular gemstones today. Additionally, Charles & Colvard provides a warranty on every gemstone, guaranteeing that every Charles & Colvard created moissanite gemstone will maintain its brilliance and fire for the lifetime of the stone. Your moissanite’s brilliance will be the same on day 3,570 as it was on day one. This helps jewelers distinguish between gemstones such as rubies and garnets. Each gemstone’s angle of refraction is unique, meaning every stone will refract light differently. When looking at your gemstone, it’s brilliance is simply the amount of light reflecting out of the crown of the stone to your eye. Similarly, the refractive index of a diamond is 2.42, meaning the speed of light in the diamond is 2.42 times slower than the speed of light in air. This means the speed of light refracting in moissanite is 2.65 to 2.69 times slower than the speed of light in the air.
With a brilliance refractive index of 2.65 to 2.69, moissanite is the world’s most brilliant gemstone. the speed of light in the gemstone.Īll minerals are measured on a scale and range from 1.2 to approximately 3. The numerical result is calculated by comparing the speed of light in air vs. What makes moissanite more brilliant than other gems?Ī stones refractive index is determined by directing light into the gemstone and then measuring the speed light reflects or refracts off its facets. You can read more about a gemstone’s fire in this blog post. Brilliance is one of three terms used to describe the appearance of a gemstone as it reflects light. When talking about brilliance in gemstones, we are referring to the light refracting in the interior of the stone, not the light reflecting off its surface. Your gemstone’s sparkle, or brilliance, is an optical property affected by its brilliance refractive index or BRI.
