diamond information

Finger size is decisive when choosing the size of the diamond. A diamond of a certain size will look larger on a small finger than on a large one.

Our advice: If you want to buy jewelry with one or more small diamonds, weighing less than 0.10 carats, talking about technical characteristics, purities, proportions, tones, and colors makes less sense than when talking about larger diamonds because these characteristics will hardly be appreciated "at a glance" in a space as small as that of a diamond less than 3mm in diameter. We would even draw the line at 0.25 carats, below which we advise buying jewelry with diamonds primarily based on whether we are captivated by its design or interested in its price, that is, we would prioritize what "our heart says" and our wallet.

If, on the other hand, you want to order jewelry that includes a larger diamond, it will be good to have some technical knowledge. There are mainly four variables that greatly affect the price of an apparently "same stone".

Diamond characteristics


  • The weight of gemstones is measured in carats (ct.). The weight of a one-carat diamond is 0.20 grams.
  • The weight measure called carat is divided into 100 hundredths or points, so for example, 25 hundredths are 0.25 carats.
  • The price of a diamond varies exponentially when its weight changes, that is, 5 diamonds weighing 0.10 carats each do not cost the same as one diamond weighing 0.50 carats.
  • The price of diamonds increases for certain specific weights such as 0.50 or 1 carat. Thus, sometimes the public values a diamond of 0.50 carats more than a diamond of 0.52 carats, or values a diamond of 1.00 carats more than a diamond of 1.03 carats.
  • The diameter of the diamond increases much more slowly than its weight. A diamond with a diameter of 5mm weighs approximately 0.50 carats while one with a diameter of 4mm weighs slightly less than 0.25 carats.

diamond sizes


  • Clarity is the measure of the number and size of natural imperfections that exist in all diamonds. Most of these imperfections are microscopic and do not affect the diamond's beauty. Many experts consider clarity the least important of the four basic characteristics that are evaluated, but its importance grows when the diamond increases in size because the facets are larger, and the imperfections become more visible. The most commonly used scale for jewelry ranges from FL to P3 and is a division into 12 grades that go from the highest clarity grade (FL or Flawless) to grade P.
  • Using a 10X loupe and expert eyes, diamonds are classified with the ones with fewer and smaller imperfections receiving higher clarity grades.
  • We do not sell diamonds, even small ones, with clarity lower than SI1, and most of them are VS.

diamond clarity


  • Ideal: An exquisite cut but very scarce. It reflects almost all the light that enters the diamond.
  • Very good: It reflects almost the same light as an ideal one and has a lower price.
  • Good: It reflects most of the entering light. Much more affordable than a very good cut.
  • Fair: It is still considered a quality diamond but does not shine as much as a good one. We do not offer these diamonds.
  • Poor: Most of the light is not reflected correctly. We do not offer these diamonds.

Color: IGI scale for diamond color

  • Color is intended to evaluate how white a diamond is: The less color it has, the higher the grade or "color quality." The best color grade is D, while the lowest is Z. The human eye tends to detect brightness before color, so it is generally considered the second most important characteristic when selecting a diamond.
  • D: The best color grade, for the whitest diamonds.
  • E: Minute traces of color detectable by an expert gemologist.
  • F: Slight traces of color detectable by an expert gemologist.
  • G/H: White with traces of color, detectable only when comparing a diamond with another of better grade and made by an expert gemologist.
  • I/J: White with traces of color, difficult to appreciate with the naked eye. Diamonds with an excellent quality-price ratio.
  • K/L/M: Slight touch of color. Interesting and economical to be mounted at a good price on yellow gold, as it better disguises its slight color or lack of whiteness. They are diamonds with the best price-size ratio.

diamond colors

There are also diamonds with intense colors. They are called "Fancy" or fantasy. They are very rare and have a much higher price than their colorless equivalent.

Our classification

  • Collection Quality: Color D/E, IF/VVS1 purity, EXTRA cut. The top, the best River color, the best purity, and the best cut that can be achieved for a diamond. Its price is high, but the result seen in the jewelry will be "spectacular." For those who want the best possible quality in the world of diamonds.
  • Superior High Quality: Color G, VVS1/VVS2 purity, EXTRA cut. Its Top Wesselton extra-white color and its purity give the diamond a bright white color and a luminous shine. The extra cut gives it an extra sparkle. For those looking for very high quality.
  • High Quality: Color H, VS1 purity, EXTRA cut. The Wesselton color ensures that the diamond is white. The VS1 assures us that its inclusions are imperceptible. The extra cut gives it exceptional brilliance. For those who want high-quality diamonds at a reasonable price.
  • Medium Quality: Color G/H, VS2 purity. A perfect balance between color and purity. They are diamonds of a quality adjusted to affordable prices.
  • Commercial Quality: Color H, SI1 purity. Diamonds with a good Wesselton color and with a very small inclusion that can only be seen with a 10x loupe. Diamonds of very reasonable quality at a very affordable price. For very tight budgets.
  • Economic Quality: Color I, VS2/SI1 purity. Economical diamonds where the color is just below Wesselton and, although they have a very slight tint, once mounted, it is difficult for most non-professionals to perceive it. Very good brilliance and a very accessible price.

In summary...

  • Once the diamond shape is selected, the other characteristics are chosen in order of importance to the customer so that it fits their budget.
  • If the most important characteristic for the buyer is carats - the weight and size, for instance - it is better to choose a good cut, at least a color grade of I or J and a clarity of Si1-Si2.
  • Diamonds with imperfections that are not visible to the naked eye are excellent and less scarce than FL-IF, therefore more affordable.
  • Color grades from G to J have an excellent quality-price ratio, and their color is hardly distinguishable by someone who is not an expert.
  • For a higher budget, colors D to F are the most scarce and therefore the most sought after.

Diamond jewelry as an investment

  • Diamonds are considered a safe investment, as they have always retained their value in case of economic crises.
  • Historically, the price of diamonds has gradually risen, as they are increasingly difficult to find and therefore more scarce. Consequently, they can be a hedge against inflation, but their resale value will depend on the supply and demand of consumers at that time.
  • A piece of diamond jewelry should normally be considered for what it is, a perfect accessory that will last forever, and not as an investment.
  • Diamond jewelry, viewed as a future investment, should be with large, perfect diamonds without impurities, with optimal brightness, and generally cost thousands of euros.
  • Any investment diamond must always be accompanied by its corresponding certificate, recognized worldwide. These certificates are large and extensive, they are a detailed report created by gemological laboratories, where experts analyze the diamond with precision equipment, microscopes, and other tools to determine its characteristics, such as weight, color, purity, symmetry, etc. Therefore, it is not advisable to request certificates for small diamonds (less than 0.50 carats) as the cost of the certificate, in relation to the value of the stone, could be disproportionate.
  • These are the most respected laboratories in the diamond industry are recognized for their reliability and the impartiality of their diamond classification systems:
    • GIA: Gemological Institute of America
    • HRD: Based in Antwerp, Belgium
    • IGI: International Gemological Institute

Our diamonds are ethical and conflict-free

  • Conflict diamonds, also known as blood diamonds, were illegally traded and uncut diamonds used to fund wars and gain power in certain areas of Africa. Today, these types of stones represent less than 1% of the world's production.
  • In July 2000, the diamond industry adopted a zero-tolerance policy towards conflict diamonds and created the "Kimberley Process Certification Scheme" to eradicate conflict diamonds and ensure that diamond resources in these countries contribute to their economic and social development. Currently, more than 70 countries have included this certification scheme in their legislation, and the EU is one of them.
  • The brands we distribute guarantee that all their diamonds are ethical by complying with these strict international standards.
  • As an alternative to traditional diamonds, laboratory-grown diamonds have recently started to be commercialized, imitating the process that the earth takes thousands of years to create.
  • All diamonds that come with the jewelry we offer are natural (mined) diamonds and not laboratory-grown. However, we provide information about these other diamonds if you want to have a special piece of jewelry made with a laboratory-grown diamond or if you want to order a loose diamond of this kind from us.

On both our website and in our physical store -dedicated exclusively to engagement rings and wedding bands- we show you a wide range of models made of gold, platinum, carbon, titanium, steel, tantalum, zirconia, silver, etc.
