What Is Platinum?

Beginning shoppers may not even be aware of the different types of metals for ring bands, such as white gold, yellow gold, and platinum. Platinum is a natural white metal, never fades or changes colour, and enhances the brilliance of diamonds. Because the platinum ring never fades or changes colours, it is perfect for everyday wear. Typically, platinum is close to pure, making it one of the purest precious metals. The purity of the platinum makes it naturally hypoallergenic. Therefore, it is recommended for people with sensitive skin. Another benefit of platinum is it's strength and durability. It is important to know the purity content when purchasing a platinum diamond ring, typically the more pure it is, the more expensive it is. Federal regulations require a hallmark imprinted on the inside of the ring stating its purity percentage. Most platinum rings are 90 to 95 per cent pure and the remaining is mixed with other metals to make it hard enough to be worn as jewellery. The strength of the metal helps make it one of the most secure settings for diamonds.

Difference Between Platinum and Gold

A buyer that does not have much experience shopping for jewellery may not even be able to tell the difference between white gold and platinum, although there are multiple similarities and differences between platinum and gold. Gold rings include are difficult to bend, scratches less often, contain rhodium plating that wears off, and they are less expensive. Platinum rings maintain colour and shine longer, are heavier, more exclusive, and more expensive. When brand new platinum and white gold rings are side by side, the colour looks very similar but over time the rhodium on the white gold rubs off, making the white gold appear dull. When evaluating the shine, initially white gold appears shinier, but platinum retains its shine for a longer period of time. White gold is a stronger metal, therefore, making it harder to scratch than platinum. Typically, gold is less expensive than platinum because platinum is more exclusive.

Overall, there are several advantages to purchasing a platinum diamond ring, including: maintaining its colour better, it does not yellow, contains a unique soft and tender look, and it is more precious and exclusive.

Colour, Clarity, Cut, and Carat

In order for a consumer to select the perfect platinum diamond ring, he or she must understand how to evaluate diamonds. Diamonds are judged based on colour, clarity, cut, and carat.

Diamonds are valued by how closely they approach colourlessness, hence, the presence of a yellow tint lowers the price of the diamond. Many of the colour distinctions are hard for the untrained eye to see but even the slightest differences make a huge difference in quality and price. The colour of the diamond is graded on a scale beginning with the letter D, representing colourless, to the letter Z, which is light yellow or brown.

Amount of Colour




D, E, F

Differences can only be seen by gemologists; recommended to be set in white gold or platinum

Near colourless


Only traces of colour can be seen, recommended to be set in white gold or platinum

Faint colour


A yellow tint can be detected by the naked eye, recommended to be set in yellow gold

Very light colour


Easily seen yellow or brown tint and are typically much less expensive

Light colour


A lot of colour present and typically not recommended for a white diamond.

The amount of colour is ultimately a buyer's personal preference, and selecting a diamond with a lower letter grade may allow the buyer to purchase a diamond with greater clarity.

Diamonds are formed deep within the earth, under extreme heat and pressure, and often contain imperfections. Diamond clarity refers to the degree to which imperfections are present. Imperfections inside of the diamond are referred to as inclusions, whereas imperfections on the surface are known as blemishes. The clarity grade is based on the size, nature, position, colour or relief, and quantity of clarity characteristics visible under 10x magnification. The clarity scale grades include: flawless, internally flawless, very very slightly included, very slightly included, slightly included and included.

Cut refers to a diamond's proportions, symmetry, and polish. People often confuse cut with shape, and they are not the same. Examples of the shapes of diamonds include: round, oval, or pear; whereas, cut sparks the diamond's fire, sparkle, and brilliance. The table, width, and depth all need to be evaluated when grading the diamond's cut. Diamond's cut grade varies from excellent, very good, good, fair to poor.

Finally, carat is used as unit of weight and is equal to 0.2 g. The price of two diamonds with the same carat size can vary because of the differences in cut, clarity, and colour. The larger the diamond is, the more rare it is, hence the higher price. Overall, it is the consumer's decision of which of the four Cs is most important. If the consumer knows how much money he or she would like to spend and the exact carat size, then they may have to compromise on colour, clarity, or cut.

Determine Ring Size at Home

The wearer's ring size can easily be determined at home with the help of some basic supplies. The supplies necessary, include: a string, pen, and ruler or tape measure. The string must be at least 10 cm long. Next, wrap the string around the base of the finger to be sized, it should not be too snug or too loose. Take the pen and make a mark on the string where the circle is complete. After that, on a flat surface lay the string next to the ruler and measure from the beginning of the string to the mark. Use the measurement to find the wearer's ring size. Typical ring sizes vary from G to Y and coordinate with string lengths measuring between 4.6 cm to 6.8 cm.
