Details to take into account when purchasing high-quality jewelry
THIS IS THE GUIDE TO EVERYTHING YOU ARE INTERESTED IN TO CHOOSE A GOLD AND DIAMONDS JEWELRY OF THE BEST QUALITY PRICE. WE EXPLAIN TO YOU WHAT TYPES OF GOLD AND WHAT QUALITIES OF DIAMONDS YOU WILL FIND ON THE MARKET AND IN ARELANA:

TO MEASURE THE QUALITY OF JEWELRY WE MUST KNOW HOW TO DISTINGUISH TWO UNITS OF MEASUREMENT:
THE KARATS (KTs) OF GOLD WHICH EXPRESS THE PURITY AND THE KARATS OF DIAMONDS OR PRECIOUS STONES (CTs) WHICH INDICATE THE WEIGHT.
1. GOLD:
Gold is a precious metal that is known as the safe haven asset par excellence because in the long term it maintains its value and does not wear out.

18k gold is the most commonly used standard gold for jewelry because it has the exact quality to maintain its shape and purity .
In Arelana you can find 3 colors and alloys of 18k gold with 75% pure gold.

Yellow gold has an alloy of silver and copper in equal parts and rose gold has a little more copper and less silver to achieve the copper color. White gold is alloyed only with white metal, which can vary between silver, nickel, platinum or palladium, as well as a rhodium plating to improve the whiteness and shine like the rest of the alloys, otherwise it would be a bit matte.
2. DIAMONDS
Diamonds are the most sought after and most used gemstones for jewelry and specifically for engagement rings. Here we will summarize the important terminology to answer the questions you should ask yourself when purchasing a diamond.
- The color:
Diamond color is classified according to the GIA color scale, from D to Z. D is classified as the most colorless and therefore the most in demand and highest cost.

At Arelana we ensure the best quality-price. We offer H color diamonds , which offer an almost colorless tone and totally transparent to the human eye. We consider that working in color G or higher greatly increases the cost and the difference is not perceived.
If you want an Arelana diamond in a different color than the one offered, do not hesitate to write to us through the contact form and we will adapt the piece and budget according to your needs.
- The clarity:
The size of the impurities and imperfections is what determines the clarity classification of a diamond and they are grouped between eye-clean, which means impeccable, perceptible to the eye, and non-eye-clean, which means that it has defects or imperfections visible to the human eye.

Arelana's VS2 diamonds will be EYE - CLEAN of high quality, no imperfections will be seen with the naked eye.
If you want an Arelana diamond in a different clarity than the one offered, do not hesitate to write to us through the contact form and we will adapt the piece and budget according to your needs.
- The certifications:
At Arelana we only offer certificates for stones from 0.5 ct / half carat because we believe that the stones are important enough and deserve it.
Certifying laboratories:

These are the certificates that we offer at Arelana for our jewelry.
For pieces less than 0.5 ct, we include an explanatory card with details of the type of diamond that has been purchased.
In any case, it is possible to certify any of our jewelry , remember that for pieces smaller than 0.5 ct, it will have an additional cost of around €70. For more information you can make a query through our contact form.
- The price:
The price of diamonds will vary depending on provenance, color, clarity and certification. The larger the diamond, the more difficult it is to obtain and the more expensive it is. But you don't have to spend more to get something of similar beauty. Our proposal is to provide the greatest value, at the lowest possible cost, making fine jewelry more accessible.
Remember that the weight shown is the sum of all the diamonds that a piece of jewelry may have, not just the largest diamond.
Now that you have all the information, remember that in Arelana you are acquiring something of very precious value that can be inherited for generations, increasing its value.
NATURAL DIAMONDS FROM ARELANA VS. LABORATORY DIAMONDS
Laboratory diamonds, also called synthetic diamonds, are apparently diamonds with the same physical appearance as diamonds extracted naturally, they are considered replicas, made by man.
The creation process of both is similar, in an environment of very high temperature and very high pressures, one underground and the other in laboratory chambers.
