So, for romantic occasions that is in need of a celebration, diamond jewellery, especially rings is a must.

Right diamond for the most brilliance

Cut referring to diamond’s proportions, symmetry and polish. It is the most important characteristic of a diamond, because it has the biggest effect on brilliance. The excellent grade ideal diamond, reflects nearly all of the light that enters the diamond, creating exceptional sparkle and fire.

Shallow diamond cut, entering light strikes the pavilion facet at a low angle and passes through the facet (refracts), escaping through the bottom of the diamond. The leakage in light, result in losing of Brilliance, Sparkle and Fire.

Deep diamond cut, entering light strikes the first pavilion facet at an angle sharp enough to reflect to the second pavilion. But the light strikes the second pavilion at too low an angle, causing the light to refract (pass through the facet), escaping through the bottom of the diamond.

Ideal diamond cut, the light strikes each pavilion facet at an angle which allows most of the light to reflect back to the crown (top). This gives the diamond a bright looking appearance and enhances its luster.

Diamond Colour

Colour of the diamond, is the second most important factor after carat size, as it has a more significant impact on its appearance. It is known that diamond closest to colourless, with better light absorption, has an optimum visible sparkle.

D colour being the highest colour grade. Extremely rare, as such command the highest price.

E – F  both near to colourless. They can be detected, side by side by expert gemologist. Relatively cheaper option compared to D colour.

G – H  slight trace of colour detectable, only when comparing side by side with higher grade diamond. Excellent value for money in price.

I – J  usually detectable from naked eyes with slight warmth colour. Common in the market where prices and discount are much attractive.

K – Z  as the yellow intensity increases, prices escalate as the diamond are much more brilliance and with fire. Such fancy diamonds are known as yellow diamond.

The colour grade range from F & G, are close to colourless. These are better value diamonds, as there are more discount, compared to D colour.

Diamond of lower colour grade such as H, I, J with fluorescence tends to look whiter. If you are deciding for a wedding proposal ring, with a priority on carat size. Consider the option of of H, I, J with medium blue fluorescence, this balance the light yellow in the diamond.

Diamond Clarity for wedding engagement ring

Diamond Clarity

Diamonds are natural minerals from the ground. Over the years under the extreme heat and pressure. They have tiny imperfection in them, known as inclusions or on the surface known as blemishes. Clarity of a diamond define as the absence of such inclusions and blemishes.

FL – IF (Flawless – Internally Flawless)

Flawless referring to no inclusions or blemishes in the diamond under a 10x magnification. Extremely rare, prices for Flawless is the highest as it is < 1% of the diamond in the market.

Internally Flawless referring to no inclusion, but only blemishes are detectable under 10x magnification. Comparing with Flawless, they are almost identical, < 3% of the diamond in the market.

VVS1 – VVS2 (Very Very Slight Inclusion)

Inclusion are very difficult to detect under 10x magnification even with a skilled grader. VVS1 inclusion are normally on the pavilion, whereas VVS2 inclusion are on the crown and not the table.

VS1 – VS2 (Very Slight Inclusion)

Inclusions are not visible under naked eyes, easily detect under 10x magnification. Inclusion are normally on the table of the diamond and some VS2 grade might have black dot.

SI1 – SI2 (Slight Inclusion)

SI1 inclusion or black dot are noticeable and able to detect under naked eyes, without magnification.

SI2 inclusion or black dot on the crown and table are noticeable under naked eyes.

I1 – I3 (Imperfection)

Heavily included, which may affect the transparency and brilliance of the diamond. These grades are not advisable for diamond jewelleries.

Excellent, Polish – Excellent & Symmetry – Excellent, Guaranteed Ideal cut?

Proportion on how the diamond is cut makes tremendous difference. We take into consideration on Depth %, Table %, Crown angle, Pavilion angle and Culet %.

none Fluorescence and medium blue what's the difference engagement diamond ring

Fluorescence – Fifth criteria you need to consider other than the 4Cs

What is Fluorescence in a Diamond?

Diamond with fluorescence, contain particles that emit a soft coloured glow when exposed to ultra-violet lighting (UV-Light). There is a tendency to emit such glow, under ultraviolet (UV) rays from natural sunlight and fluorescent lamps. Such glow could emit a bluish or yellowish light. In certain cases, strong blue fluorescence can cause the diamond to appear milky or hazy. Fluorescence in the diamond are categorise to faint, medium, strong blue and very strong blue.

Does Fluorescence affect Diamond’s value?

Nearly 30% of the diamond in the market, exhibit fluorescent properties under ultraviolet light source. Prices of diamond varies from the 4Cs(Carat, Colour, Clarity and Cut), and from the degree of fluorescent. Some consider fluorescent as a negative characteristic, as such they command a lower price as compared to non-fluorescent diamonds.

Fluorescent can be an advantage or disadvantage to different colour grade of diamonds. In the colourless (D, E, F, G, etc), the diamond tends to look blur or milky. As for lower colours (I, J, K, L, etc.), they appear more colourless to white.

Balance within the 4Cs and 1F in diamond

Diamond with excellent facets cut will allow most of the light to reflect back to the crown. Hearts and Arrows cut have always been known to give the best performance of an ideal diamond. Having VS1 – VS2 in clarity, will allow you to save on your budget. With the fire and brilliance from the excellent cut, it will allow the inclusion to hide away from the naked eyes.

If your main concern lies in the size of diamond, fret not, as you will still be able to get one that is value for money. It is always the psychological and emotional perception that affect the consumer’s decision in selecting the right carat size. Often, diamond which are close to 1.0 carat, i.e 0.8-0.9 carat will cost much higher than 0.6-0.7 carat, we called this a price jump in carat. Therefore, if you are looking for a good value size of diamond which is near 2.0 carat, do take a look at the price for 1.5-1.7 carat.

In the range of F – G colour, the diamond would appear to be colourless under the naked eyes. This colour disparity between the D – E colour range is almost impossible to detect without comparing them side by side. However, the price differences between these two colour ranges differs significantly.

Take advantage of the discounted price of a diamond with minimum fluorescence, from faint, medium, strong blue and very strong blue.
