How To Pick The Perfect Diamond Engagement Ring?

Diamond Engagement Rings Perth

When picking the perfect engagement ring, there are six questions you will need to answer.

Size of Engagement Ring: You will need to know the size of your fiancée’s ring finger. This is located between the pinky and the middle finger on the left hand. In some cultures it is the right hand, but in Australia it is traditionally on the left. If you need clarification on other cultures please contact us. The reason the diamond engagement ring goes on this finger is that, it is believed there is a vein running directly from this finger to the heart—how romantic.

The type of metal: If your partner likes white gold or platinum, it would be disastrous to buy a yellow gold ring. They will not like wearing the ring and it will have to be remodeled, in turn costing you more money. Most engagement rings are either made from:

  • 18ct Yellow Gold
  • 18ct White Gold
  • Platinum 
  • Two Tone (A mixture of white and yellow, usually the setting is made of white gold and the band, yellow gold).

Type of setting: The setting is what holds the gemstones in the ring. This can change dramatically depending on the number of gemstones you are wish to invest in. There are different types of settings, the most popular being:

  • Bezel (metal around the whole stone) 
  • Claw (being held by numerous wires)
  • Pave (lots of gemstones in one area)
  • Channel (stones all set in a row)

Type of gemstones:
The type of gemstones used will be the biggest investment in the engagement ring, so it is imperative that you know this.
Diamonds are the most common used gemstone for engagement rings but that doesn’t mean they are the only gemstone used. Other gemstones used are rubies sapphires, emeralds and even pearls. A combination of these can also be effective depending on your partners preference.

Other options you need to know when picking that perfect gemstone are:
Colour: Most gemstones (including diamonds) come in an array of colours so it is very important to know what colour your partner would love the most. They will be wearing the ring for a long time.
Size: The size of the gemstone will change the price massively so it is advised to know approximately what size will fit within your budget. Your jewellery designer will help you make a choice.

Shape: Gemstone’s come in all different shapes. Your partner will more than likely have a preferred shape. This will change the design of the ring and can make for some unusually shaped engagement rings. This is a great way to really make your engagement ring unique. Some of the more common shapes are:

  • Round Brilliant Cut
  • Princess Cut
  • Emerald Cut (Not necessarily an Emerald)
  • Pear Shape
  • Baguette 
  • Trillion 
  • Marquise
  • Heart
  • Radiant
  • Oval
  • Cushion

A good way to get a grasp of what your partner likes is to observe the rings she gravitates to, or even ask someone who would know. This could be a close friend or relative, another way is to leave a few catalogues around the house to see what they look at as points of interest.
A jewellery designer can also help you. The best arrangement would be to book a consultation and work in conjunction with a designer to create the perfect engagement ring according to your desired specifications.

What are the pitfalls of choosing your perfect diamond?

Diamond prices are determined by the four C’s, these being Cut, Colour, Clarity and Carat.

Clarity: The clarity of a diamond is determined by the amount of inclusions and blemishes in and on the stone. It depends on the number, size, relief, nature, and position of these imperfections, as well as the way it affects the overall appearance of the diamond. The less imperfections the diamond has, the better the stone and in turn, the higher the price.
The grading of the stone is done under a 10x magnified glass called a loop, so the difference between a FL and an SI2 cannot be seen with the naked eye.

Carat: The “ Carat” refers to the weight of the diamond. A carat traditionally weighs 200 milligrams and is divided into 100 points.The price per carat gets more expensive as the stones get bigger. This is because bigger stones are more desirable and rare. When purchasing a diamond the bigger stones are not always the most expensive as the other three C’s play a major part in determining expense.

Cut: The cut is very important when choosing a diamond. This can change the price of a diamond dramatically and in my opinion is the most important of all four C’s. If a diamond is poorly cut, the light won’t refract as brilliantly as a well cut stone. When grading a stone on cut, the scale is split into five categories: poor, fair, good, very good and excellent. The grade is evaluated on how well the diamond interacts with light to create such effects as:

Fire: The scattering of white light into all colours.

Brightness: External and internal bright light reflected from a diamond.

Scintillation: The amount of sparkle within a diamond, and the pattern of dark and light areas caused by reflections within the diamond. Other characteristics that are taken into account are the thickness of the girdle, how well the facets are polished, and its weight compared to its diameter.

A well cut stone will have the light come through the table of the stone, refract in a square and come out of the table exuding brilliant sparkle and fire. If a stone is cut shallow or deep the light will get lost through the pavilion and will, in my opinion, appear dead.

Colour: Colour refers to how white a diamond is. The less colour the stone has, the better the quality.

To determine this, there is a colour scale from D to Z. Most of these increments cannot be seen by the naked eye but the difference between a D and Z is very significant.

  • D-F= is colourless, pure white
  • G-J= Near colourless
  • K-M=Faint
  • N-R =Very Light
  • S-Z =Light

Picking the right Stone

When choosing the right diamond it helps to find a happy medium you are comfortable with between quality and price. Having imperfections in your stone should not be seen as a bad thing. Like all things, natural isn’t always perfect. The flaws are what give it its character.

When buying a diamond always ask for a GIA certificate (Gemological Institute of America) so you know that you are getting a real diamond. Some quality control of other certificates out there are not as good, so be careful.

When getting a valuation from a jeweller for a piece of jewellery or a loose diamond, be sure that the valuation is done by a certified valuer. There will be a personal certification number unique to the valuer at the bottom of the page. If it does not have this, it is merely what the retailer or seller thinks it’s worth. The two can often be very different.
