This is the final Diamond Tutorial for October, I hope the information and thoughts we’ve provided through the month have helped in some way. One last lesson today concerns ‘Table Percentage’
Diamond Tutorial: What is Table Percentage?
Table Percentage: This is the value representing how the diameter of the table facet compares to the diameter of the entire diamond. As such, a diamond that shows a 50% table has a diamond table which is 50% as wide as the outline of the diamond. Professionals in the industry calculate the actual table percentage by dividing the diameter of the “table” (measured in millimeters) by the average width (or girdle) diameter. Popular confusions are that a small table percentage (50% to 53%) does not make a round diamond any more brilliant than a diamond with a larger table.

One of the key important moments in a person’s life is when they get engaged. Getting engaged implies that an engagement ring is required. Engagement rings with a high ratio offer couples a classy engagement ring diamond selection. Engagement rings with a high ratio are ideal for that once in a life time occasion, but what is ratio?
Diamond Tutorial: What is Ratio?
Ratio: The ratio is a comparison of the length of the diamond and the width, simple as that, but there’s more to assessing the ratio than words!. The ratio is is used to analyze the outline of fancy shaped diamonds and never used to measure round diamonds. For quick reference, there’s no measure of an ‘ideal’ ratio. Simply a matter of personal choice and preference. EG: many people believe that a 2 to 1 ratio is best for a marquise though most people actually tend to prefer a ratio of around 1.80 to 1 when they actually look at marquises.
People today are more and more putting a premium on being unique and different, having a unique diamond set into some stunning ring or necklace sourced online is one of them. You can create stunning diamond jewelry with great florescence from loose cut diamonds by creating your own design and having them set in the kind of setting you want them to be in. But what is Fluorescence?
Diamond Tutorial: What is Fluorescence?
Fluorescence: Fluorescence is a diamond effect seen in some high quality diamonds when exposed to a long-wave ultraviolet light (in many sense, its the same light seen in nightclubs). Under the majority of light conditions, diamond fluorescence will not be detectable to the naked or untrained eye. However, if you’ve found a diamond that claims to be naturally fluorescent, you should see a soft glow when you hold it under a simple ultraviolet lamp. Fluorescence is not dangerous to the diamond or to the wearer; it is a unique and fascinating quality that occurs naturally in a number of gems and minerals.
Giving the perfect engagement (or wedding) ring to your sweetheart does not mean that you have to spend a lot. You can find top loose diamonds of lower price, which you can then design into the dream ring for your lady. Today, learn a little more about diamonds, ‘feathers’ are something you should understand and know what to look for.
Diamond Tutorial: What are feathers?
Feathers: Feathers are are tiny fractures within the diamond. Usually feathers are caused by the incredible stress that the diamond can and likely has suffered during its gestation period underground. There are many cases where the feather begins and ends under the surface of the diamond. Sometimes the feather can start deep inside the diamond and extend out towards the surface. You will need to see this under 10x magnification since some feathers are transparent. In general , feathers have a white light appearance to them making them difficult to detect. Under magnification, these feather fractures often seem to have an disorganized feathery shape.
It may seem like a red flag if you detect feathers in a diamond, however, the reality is that with everyday wear and care most feathers do not add risk to the diamond’s stability or long term viability and value. You should bear in mind that these diamonds have survived their growth and their journey to the earths surface intact and then they’ve been through the rigours of the cutting and polishing processes before you get a chance to see them. With everyday wear most will likely survive the course of several human lifetimes.
Getting engaged? need a diamond engagement ring? or just a cute present for the one you love for no reason other than a mutual appreciation for the beauty of diamonds and the meaning they convey when bought and given as a gift.
Diamond Tutorial: What is a Facet?
Facet: The ‘facet’ is the part of the diamond that displays a smooth flat face upon the surface of the diamond. Facets allow the light to enter the diamond and then also to reflect off its surface. When reflected at different angles the effect is the creation of stunning color and light, the kind of light show that have made diamonds famous.
