MANUEL Spinosa Diamonds


Our Quality Standards

The quality of diamonds is measured through 4 main characteristics, called the "Four C's":


•Size (Cut)
•Color (Colour)
•Purity (Clarity)
•Carat weight (Carat weight)

CUT

These are the most important qualities and what makes the difference between our diamonds from the others.  For a diamond to reflect brilliance and shine more, it must be cut perfectly. A diamond with good colour and good purity but of poor cut can get very expensive. The cut will not be able to provide the diamond shine and instead will have an opaque feature.

 

COLOUR

The second most important quality a diamond has is its colour tone ranging from the perfect white (transparent) to yellow. The whiter the diamond is the more light it reflects but this is rare and difficult to achieve.  There are several tricks however, to find the perfect balance between colour and price of the diamond. 


 

PURITY

This quality measures the number, the location, size and type of inclusions or internal brand that a diamond has. The purer the diamond, the brighter it reflects and, therefore, is more scarce and valuable. Read several tips to find a balance between purity and right price. 

 

CARAT WEIGHT

The weight of a Diamond also determines its price. A diamond of 1carat can cost 4 times more than one 0.50 carat. In this section you will learn how to relate the weight of a diamond to size and to choose diamonds according to its weight.

 

 

CERTIFICATION

We recommend to never buy a diamond without certification! The certificate of the diamond, issued by an independent laboratory, is the only guarantee that allows evaluating the quality and thus its price.

Without a certificate, the price of a diamond is impossible to determine, and this runs the risk of paying up more than double of its actual value.  

Learn which jeweller sells diamonds with certificates, and why you should require certificates of diamonds to get maximum guarantees.

Diamonds have always been, in the long term, a very profitable investment rather than financial or real estate markets, apart from offering a number of additional advantages.

Be careful with..
The most important quality of a diamond is its size. A poorly cut diamond does not shine
despite having good colour and purity. Manuel Spinosa rejects wrongly cut diamonds.
