Diamond spread is just a measurement of a diamond's table size when viewed from the top. (Remember that the table of a diamond is the flat facet that you see when looking at it straight on, like the top of a table.) It is the apparent size of a diamond based on its carat weight. Because the reflection (not refraction) is greater, a 1ct diamond with a wider spread will appear larger than a 1ct diamond with a narrower spread. Is there a perfect diamond spread? It's something to consider on a case-by-case basis, depending on the shape of a diamond. For each diamond form, we've included these measurements. (For example, in a round cut diamond, the optimal range for the table facet is between 54 and 61 per cent.)
You'll receive a bigger stone with optimal sparkle if you choose a diamond spread within those recommended ranges without compromising brilliance or spending more than you need to. Work with a gemmologist — like one of our on-staff specialists — to determine the right depth and table measurements so you can choose the perfect diamond spread.
Another factor is that many buyers lack an in-depth knowledge of what makes up a good or bad diamond. And so, even though they may be well aware of the 4 Cs - Cut, Clarity, Colour and Carats – their purchases usually rely on either professional advice or brand name recognition or simply on intuition. For others, there's nothing more satisfying than picking their own diamond according to specific requirements that they themselves have set based on personal preferences. It doesn't matter where you are in the diamond industry, whether you are considering buying a diamond for yourself or your family, or whether you are in the business of selling diamonds to retailers or consumers. You can use this article as a basic guide for understanding what makes up the quality of a diamond and how it should affect your buying decisions.
The only thing that makes a lab-grown diamond different from a natural diamond is its origin. A lab-grown diamond is “grown” inside a lab using cutting-edge technology that replicates the natural diamond growing process. The result is a man-made diamond that is chemically, physically, and optically the same as those grown beneath the Earth’s surface.
For every carat of diamond that is mined, nearly 100 sq ft of land is disturbed and almost 6000 lbs (2.7 tonne) of mineral waste is created
Our collection of ethical and affordable conflict-free grown diamonds are more beautiful than anything we will ever get out of the earth and come free of any negative environmental or social impact.
Lab-grown diamonds have the same exceptional hardness, stiffness, and thermal conductivity as their Earth-mined counterparts.
Lab created diamonds offer excellent value, and are scientifically more affordable than natural diamonds of comparable size and quality.
Clarity refers to the degree of internal or external blemishes visible when looking at a diamond through magnification. There are many sources of clarity related defects such as naturals, feathers, pinpoints and clouds. Though these are naturally occurring imperfections, they have always been considered undesirable they take away from the beauty of the stone.
Diamond shape and size affect clarity. While clarity is less important than a diamond’s cut or color, if you are buying a diamond over one carat or considering certain fancy-shaped diamonds (like an emerald or Asscher cut where flaws are more visible), you may want to spend more for a higher clarity grade.
Diamond clarity is an important characteristic that affects a diamond’s beauty. Like all of the 4Cs, diamond clarity is an important consideration when buying a diamond. While clarity affects price, there are a number of factors that can help you decide which clarity grade is right for you.
It’s also important to note that diamonds with the fewest and smallest inclusions receive the highest clarity grades—and higher price tags to reflect that.
The cut is one of the most important factors in determining the beauty and brilliance of any diamond shape. Cut is graded on various characteristics including symmetry, polish, angles and proportion ratios. Cut grading is usually subjective because there are no universally accepted standards that vendors must follow when assessing cut quality. Cut grading varies not only from vendor to vendor but also from country to country. As such, don't be surprised if two completely different descriptions are given for the same stone. Cut grading is not very relevant to round diamonds because their cut can be easily controlled through proper polishing techniques. Any irregularities in cutting would affect other shapes more, particularly fancy cuts with complex faceting arrangements. Many diamond experts feel that there should be an official industry standard for cut assessment, but no one has yet come up with a comprehensive system that satisfies everyone's requirements.
A diamond cut is a style or design guide used when shaping a diamond for polishing such as the brilliant cut. Cut does not refer to shape (pear, oval), but the symmetry, proportioning and polish of a diamond. The cut of a diamond greatly affects a diamond's brilliance; this means if it is cut poorly, it will be less luminous.
The most popular of diamond cuts is the modern round brilliant, whose facet arrangements and proportions have been perfected by both mathematical and empirical analysis.
Diamond cutters must consider several factors, such as the shape and size of the crystal, when choosing a cut.
The colour of a diamond is graded on a D-Z scale, with D denoting perfect colourlessness (and hence the most expensive) and Z denoting a mild yellow hue. Standard diamond quality, according to Mills, is in the D-J colour range. The position of the diamond on the colour scale is also influenced by its shape. For example, a dazzling round diamond hides colour exceptionally well, allowing you to move further down the scale without showing any yellowing. Longer diamond forms, such as circular and radiant, however, expose colour considerably more easily. Keep in mind, however, that diamond colour is purely a matter of taste and has no bearing on quality.
A chemically pure and structurally perfect diamond is perfectly transparent with no hue, or color. However, in reality almost no gem-sized natural diamonds are absolutely perfect. The color of a diamond may be affected by chemical impurities and/or structural defects in the crystal lattice.
Diamonds occur in a variety of colors—steel gray, white, blue, yellow, orange, red, green, pink to purple, brown, and black.Colored diamonds contain interstitial impurities or structural defects that cause the coloration; pure diamonds are perfectly transparent and colorless.
The Aurora Pyramid of Hope displays a spectacular array of naturally colored diamonds, including red diamonds.
Last but not least, carat is a measurement of the diamond's real weight. According to the Gemmological Institute of America, one carat is 0.2 grams, or about the same weight as a paper clip. Naturally, the more carats a diamond has, the more expensive it is. Because no two diamonds are exactly alike, carat should only be used as a guideline because it only identifies the stone's weight, not its size. "You can have five oval diamonds, all precisely 2.00 carats, all the same colour, clarity, and cut," Mills explains, "but they will all be slightly different sizes and shapes."
Diamonds with higher carat weights are cut from larger rough crystals that are harder to source than small crystals. So, the relationship between carat weight and price depends on the rarity or availability of a rough crystal. Carat price is also a function of finding rough crystals with desirable color, and internal and external characteristics that will positively influence clarity when the diamond is cut.
Beautiful sparkle is the result of a well-crafted cut. In fact, a high carat weight diamond with a poor cut may look smaller than a diamond with a smaller carat weight and a very good cut.
The term carat comes from the ancient method of weighing precious metal and stones against the seeds of the carob tree—which were considered to be even in weight.

WHAT IS THE DIFFERENCE BETWEEN CVD & HPHT DIAMONDS? There are several notable differences between CVD (Chemical Vapour Deposition) and HPHT (High Pressure, High Temperature) diamonds in manufacture process and quality.
HPHT-produced diamonds are produced with artificial conditions similar to how a diamond would naturally form over thousands of years in the Earth’s crust – with incredibly high pressure and temperatures. HPHT diamonds tend to be cheaper but of poorer quality than CVD-produced diamonds. Parker Diamonds utilises the higher quality CVD lab made diamonds.
CVD-produced diamonds are manufactured by using a slice of a diamond as a seed, filling a chamber with hydrocarbon gasses and breaking down molecular bonds with microwaves or lasers to bond to the seed and build into a larger crystal. These lab-grown diamonds are molecularly the same as natural diamonds, producing a brilliant shine that cannot be distinguished from a natural diamond from the naked eye. The diamonds produced with a CVD process are Type 2A diamonds, the grading for the most unique and purest form of a diamond devoid of imperfections.
