Fluorescence is the bluish light, or more rarely, a yellow or orange light a diamond emits when it is exposed to ultraviolet (UV) sources like the sun and fluorescent lamps. Once the UV light source is removed, the diamond stops fluorescing. 

For diamonds with colour I to Z,  having a very strong to medium blue fluorescence gives the diamond the illusion of a higher colour grade.

However, in the case for diamonds in the D to H colour range, it is best to have no fluorescence as it may cause a hazy or cloudy appearance in these diamonds.


At this point, it almost sounds like the jeweller has just casted a spell on you.“Triple Excellent None” is actually a term used by jewellers when a diamond has a grading like this:

Cut Grade……………………………….Excellent


· Polish…………….………………….Excellent

· Symmetry…………………..……..Excellent


In the world of round diamonds, a stone that scores an excellent rating in all 3 excellent grading in Cut, Polish and Symmetry is often considered to be the pinnacle of well-cut diamonds.


When it comes to choosing an engagement ring, there is more to it besides choosing the perfect diamond. Ring settings help add that extra special touch in enhancing your center stone’s appearance.


A solitaire setting to put it simply, is a band that holds your diamond. Solitaires are known to be the most classic of all ring settings. The solitaire’s minimalistic design allows for the diamond to be the star of the show.


A side stone setting consists of a center stone that is usually accompanied by smaller diamonds surrounding it or next to it along the band. The smaller side stone diamonds are known to give that center stone that added brilliance. There are many options designed to enhance the diamond’s beauty while emulating the personality and lifestyle of its wearer. 

Here are some of the side stone setting styles jargon you will come across:

· Pavé: Many small diamonds placed close together, usually in a honeycomb pattern, creating the appearance that the ring setting has been ‘paved’ with diamonds. 

· Halo: A halo ring setting is one that encircles a center diamond with a halo of round pavé or micro-pavé diamonds. It makes a diamond of any carat look bigger than it actually is.

· Channel: Smaller diamonds are set edge-to-edge so none of the binding metal shoes from the top which creates the illusion of a seamless diamond surface.
