In David Locco, in addition to the strict use of first grade gold of 750 thousandths, we also work on a wide range in terms of the shape of diamonds. Classified into two large groups: round diamonds and fantasy-shaped diamonds. The former, also known as brilliant, are the most traditional form and have always been distinguished by their elegance.
This is perfect for a ring, inspired by a millimeter measure capable of providing a large amount of light that, in turn, will provide a much more highlighted shine and an extremely delicate style. It can also be used as a solitaire, as a unique piece or set in different quantities, such as the wonderful alliances full of tiny diamonds, a clear symbol of discretion and delicacy. Being a wedding ring, the diamond has been and will be one of the most chosen options by the lucky ones. Without neglecting that this is also perfect to be set on both classic and minimalist earrings, giving rise to timeless pieces capable of transcending generations.
For their part, in addition to diamonds or round diamonds, fantasy-shaped diamonds are also used, which include all diamonds with shapes other than round ones. Among these fantasy shapes are princess-shaped diamonds, which demonstrate a strong, understated and solid appearance through a square design on 76 faces, of which a great deal of intense brilliance radiates.
The cushion shape can also be found with the particularity of having several elongated faces that end in rounded corners. One of the most acquired cushions over time has been and is the heart-shaped stone due to the tenderness it brings to its wearer. Ideal for both large and medium sizes, as the technique can be applied with great precision.
Finally, another of the diamonds with which the firm is most identified is known as pear or drop. Its figure stands out for its brightness and shape, providing a really special touch to those who wear it.
On the other hand, in addition to the shape, another of the most important aspects of diamonds is their color. Bearing in mind that the positioning of a diamond in the scale of the shades of white cannot be carried out by anyone who isn’t a specialist in the matter through a special light, being carried out only on unmounted diamonds.
Among these hues, there are white and colorless stones on an extremely diverse scale of tones, ranging from bright white to pale yellow. These differences are classified on a color scale ranging from D (colorless) to Z (light yellow). For this reason, beautiful diamonds of various colors can be purchased, such as blue, pink or amber. All perfectly reflected within the David Locco catalog, offering jewels of enormous beauty through a
wide range of tones according to the needs of its clients. In addition to the mentioned characteristics, quality and details are essential properties for David Locco’s creations. Their jewels allow them to be treated with confidence and delicacy, due to the solidity, strength and elegance they possess. Its diamonds, set next to the gold setting, give rise to an authentic exclusive design specially devised for exquisite tastes.
This way, all David Locco’s designs are characterized by being classic and timeless, combining and fusing this romantic style with other more sophisticated and groundbreaking pieces. The brand understands a timeless design as one that, even if time passes and new trends are adopted, will always have a useful life and will look just as current as when it was designed. This classic style of the firm and its timeless touch with infinite imagination is what allows numerous combinations depending on different tastes and preferences.
In addition to its own designs, the brand has gone one step further collaborating with numerous artists with the intention of reaching the maximum expression in its different collections, always trying to raise awareness through sustainability. Solid metal pieces and eco- friendly diamonds bathed in 18 carat gold are some of the pieces made by hand to spread this message to the rest of the world.
Scale of purity of diamonds according to their inclusions.
What determines the purity of a diamond is the quality and size of the imperfections or natural inclusions that can be found inside it.
The fewer inclusions there are in the diamond, the higher its value on the purity scale.
Diamond colour grading chart.
Colour is one of the most important characteristics of a diamond, so the more colourless it is, the better its brilliance and the higher quality it will be rated. The scale begins with the letter D and ends with the letter Z, with the letter D being the best graded (colourless) and the letter Z inferring quality (very yellowish colour) .
Purity grading with magnifying glass (10x).
It is understood that the purity of a diamond is based on internal perfection, i.e. the absence of inclusions or defects that prevent the transparency of the stone from being perfect.
By international agreement, the evaluation of inclusions is always done with a magnifying glass of 10x, and the defects that can be observed at higher magnifications are not considered in the evaluation.
Size-to-weight equivalence table for brilliant-cut diamonds.
The weight of diamonds, like that of other precious stones, is expressed in carats ( Ct.). 1 carat = 0.2 grams. One carat is divided into 100 points. The brilliant cut is so regulated that we can have a very approximate equivalence relationship between the size and weight of the diamonds.
Diamond cutting is the process which is used to give the desired shape and cut. It is the shape of the diamond once cut that will give the name to the type of cut. The quality of the cut is very important to obtain a diamond that shines. A cut diamond with good symmetry and well proportioned will always reflect light better and shine much more.
Natural diamonds vs laboratory diamonds
The organic process of diamond formation requires four fundamental ingredients: carbon, pressure, heat and time. It’s estimated that these stones appeared between 1 and 3 billion years ago in the depths of the Earth (160 kilometers under the earth’s mantle), at a temperature of at least 400 ° C.
Diamond is one of the best known allotropes of carbon, whose hardness and high scattering of light make it usable for both industrial applications and jewelry. Technically, we could say that these stones are extremely compressed pieces of coal. These precious rocks arose deep within the Earth through pipes of kimberlite, a type of volcanic igneous rock, which formed the roots of some of the most powerful volcanoes in the world. These volcanoes erupted millions of years ago, bringing diamond-studded kimberlites to the surface.
Precious stones, contrary to common believe, are not exposed in the mines themselves. Once mined from the ground, the rocks are exfoliated, carved and polished to transform into bright and attractive diamonds. This procedure exposes mine workers to work in very dangerous conditions, in addition to the time and effort required by the process.
Thus, the extraction and processing of minerals in a natural way includes a series of actions that produce great environmental impacts. In this sense, David Locco decided to lead the market for laboratory-born diamonds, thus becoming the first global firm to have certified diamonds.
In contrast to the organic process, the process of creating diamonds in laboratories begins with a diamond seed, which is subjected to a plasma reactor at more than 6,000 degrees Fahrenheit. This is what guarantees a development identical to that of natural stone.
After about 600 hours, the rough diamond grows and crystallizes, until it’s large enough to be cut and polished. It should be clarified that, during all the time in which the stone develops in the reactor, nothing extra will be added to it. It’s only allowed to grow and crystallize. The plasma discharge is established in a resonant microwave cavity and is responsible for the creation of the key species for diamond growth.
These plasmas, composed of electrons, ions, and electronically excited species, are what give the diamond its pleasant colors. David Locco’s extensive catalog of gemstones includes the main shapes that can currently be given to these diamonds, thus facilitating the acquisition of the jewel together with the desired diamond.
The result is a totally conflict-free gemstone, the production of which is not harmful to the environment. In addition, the sustainable diamonds created by the brand achieve the highest quality parameters in terms of color and clarity. The value of each gem depends on four quality criteria, popularly known as the 4C: purity (clarity) as those small natural imperfections present in all stones, the color of the stone as of more value according to its level of white or transparency, the weight in carat taking into account that one carat is equivalent to 0.20 grams, and finally the size (cut) as the only criterion that depends on the knowledge and good practice of the professional. Allowing to reveal the brilliance of the piece.
The only difference between a real diamond and one grown in the lab is its origin. Especially the fact that one took millions of years to form, while the other was created by human action under careful supervision. Although the two types of diamonds are identical to the eye, their origin stories are completely different.
Traditional diamond mining contributes to environmental pollution and has a growing negative impact on people and nature. The problem of so-called conflict diamonds, which are sold to encourage certain illegal activities, should also be taken into account.
For its part, the laboratory diamond is an ecological, socially responsible and totally sustainable diamond. It’s a diamond that shines from the outside, also created in a pure and, in this case, conflict-free way.
In conclusion, it can be said that laboratory-grown diamonds are in full expansion of both knowledge and consumption, gaining ground compared to naturally mined diamonds. Among the main reasons we find that the diamonds created by David Locco are as real as those extracted from mines and that, in addition, they are more respectful of the environment. Also taking into account that they offer the possibility of customizing their shape and size to the maximum through beautiful and timeless carvings, thus avoiding the exploitation of natural resources.
