Heart-shaped Diamond

Heart-shape diamond - brilliant diamond | Custom made jewellery

With Valentine’s Day just around the corner, are you looking for a romantic gift or a surprise engagement proposal?

Heart-shaped diamond, a classic symbol of romance and love. Heart diamond has been around for a long time, they are one-of-a-kind anniversary gifts and engagement ring. Although it might not be trendy as traditional round brilliant, they are bold and distinctive choice.

Heart-Shaped Cut 

One of the most difficult cut and require extremely dedicated skill on the shape proportion. Unlike round cut diamonds, which provide a detail grading system of cut, polish and symmetry in GIA report. Heart shaped diamonds are fancy cut diamond, which provide only on polish and symmetry. Cut grading information is not provided, as the priority is on the overall proportion. They could be too narrow cut or fat which are undesirable.

An optimum proportion heart-shaped diamond, display a balanced scintillation pattern and reflect great brilliance.

Customised Ring Setting

Heart-shaped diamonds are not constraint to just classic solitaire or halo diamond design. With customised ring setting, we can even have minimum of 3 prongs on the main stone, with one side of the prong on the vulnerable tip for security and protection.

Prong Setting

The size of the diamond matters a lot when it comes to ring setting. When the diamond is smaller in size, 3 prong setting is recommended as it does not cover too much of the diamond which might be overwhelming to it.

Twisting on the ring bands, known as “infinity knots”. With alternate row of diamonds or full diamond setting.

Side Stone Setting

Matching the heart-shaped with a pair of coloured gemstones? They could be sweet pinkish sapphire or neon greenish blue paraiba tourmaline, give a unique and stunning look to the brilliant heart.

Customised Jewellery

There are just too many options available with customised jewellery, and we believe that the jewellery should personalised and couture to your style. Each precious  gemstones and design is unique and one-of-a-kind. More of our latest update in the Highlights!

Diamond Clarity

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.

Right Diamond Clarity for Proposal Ring

Select the right clarity, for the best value for money diamond. Might not need to be flawless, but at least one that is eye-clean. One look on the diamond you are not able to detect any inclusion with your naked eyes! I believe no one will bring a 10x magnification loupe on the street.

The clarity grade of VS1 and VS2, are usually eye-clean. As the inclusion are tiny and crystal or feather in the diamonds, therefore is it quite negligible. SI1 and SI2 or below quality, inclusion are quite noticeable especially the black dots. Due to the obvious inclusions and impurities, they might affect the light reflecting of the diamond in general.

Customized engagement ring, begin from the selection of the ring diamond. Natural inclusion in the diamond or coloured gemstone is inevitable. In fact, inclusion in the stone is a way to detect the origin and whether is there any heat enhancement. Diamond with flawless, is very rare in the market, prices of such diamond are a premium compared to the rest.

Diamond Colour

Diamond colour chart

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.

Right Diamond Colour for Setting

The fact that, colour of diamonds with one level grade difference are difficult to tell, unless comparing them next to each. The setting of the jewellery affect the colour of your diamond too. If you are a person, who preferred rose gold or natural white gold for your wedding engagement ring. The colour of your diamond might not be as colourless as you thought, because the based of the ring is yellowish.

Knowing that your are getting a diamond on a lower grade colour. You might consider to customized it with a natural or yellow gold ring setting. This would further intense the diamond colour, to yellow diamond shade, as some preferred to have a warmer look on their jewellery. What’s your choice? Or do you prefer other colour shade like coloured gemstone?


none Fluorescence and medium blue what's the difference

Diamond Fluorescence


none Fluorescence and medium blue what's the differenceFluorescence – 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.

Purchase a Diamond with Fluorescence?

  • Verify the diamond GIA certification and physical diamond under UV-light source.
  • Same as coloured gemstones, view the diamond under natural daylight, as sunlight contains UV rays.
  • Some fluorescence might exhibit yellow, which might further intense the lower colour (H, I, J) grade diamonds.
  • If price of the diamond is the top priority, compare both fluorescence and non-fluorescent, of similar quality in order to decide whether you can see any difference in colour or clarity.
