At Blasco Joyero we are specialists in Diamonds

At Blasco Joyero we offer you a wide range of possibilities when buying and investing in a diamond, graphically explaining the classification that exists in diamonds and giving you advice on their characteristics. The diamond is classified among the hardest gems in the world, and hence its hardness on the Mohs scale of 10. Its name comes from the Greek, from “adamas”, which means unbreakable, invincible….. The most important characteristics of the diamond are the cut, colour, purity and weight, hence the famous explanation of the 4C, four essential characteristics for its proper classification; cut, colour, clarity and carat.

All diamonds are not the same and depending on these four basic parameters, the price can vary greatly. It is a very common mistake to compare the price of two diamonds with the same weight, if it is not done with the rest of their characteristics. To give you an idea, the price of the same diamond at the same weight can vary by more than 300%… Hence the importance of being well advised.

We can show you and offer you loose diamonds of all sizes to advise you. You can buy them certified or assembled with the type of frame that you like, to measure and to your liking, even being able to design your own assembly.

There are very specific aspects and characteristics within 4C that are very important and that must be explained and developed by a professional, among them, fluorescence, proportions, facet polishing, etc….

Let yourself be advised by a diamond specialist, certifying its quality and colour. Contact us without any obligation, we will be happy to advise you.
