How to Choose the Perfect Diamonds for Your Beau

Temple and Grace diamonds make for an impressive and romantic gift, whether they’re in the form of a necklace, ring or bracelet. But how do you navigate the complex terminology around buying them?

This article covers the basics of what you need to know when shopping for your special someone.

Selecting a colour

While Temple and Grace diamonds are typically seen as being transparent, they naturally occur in a wide range of colours. These colour variations are caused by chemical and structural impurities, and vary in price accordingly. The rarest (and therefore most expensive) colours are red and pink.

Here are the most common colours you can choose from:

  • White
  • Grey
  • Transparent
  • Black
  • Brown
  • Orange
  • Red
  • Pink
  • Purple
  • Blue
  • Green
  • Yellow

Even stones which appear colourless usually have a mild yellow tint to them. When shopping, check the grade – it varies between totally colourless to heavily tinted. Generally, the more tinted, the cheaper it will be.

Choosing a cut

The cut determines how intense and brilliant the Temple and Grace diamonds are. It includes the clarity, polish, proportions, symmetry and shape. As you can imagine, well-cut stones are more costly than poorly cut ones.



The depth and width of the stone can affect the way light travels through it; this affects its brilliance. If it is too deep or too shallow, it will look dark and dull.

After cutting, the diamonds will be polished to make them smooth and shiny. A good-quality effort will be mostly free from scratches and blemishes. Almost all stones have some blemishes but these should not be visible from the naked eye.



Symmetry describes the arrangement of the facets in the diamonds, as well as facet shape and size and the alignment of the pavilion and crown. A symmetrical stone will tend to be more valuable than an asymmetrical one, however the cutter may have to sacrifice a degree of symmetry in some cases in order to retain the weight of it.



Stones come in a range of shapes, including:

  • Asscher
  • Cushion
  • Emerald
  • Heart
  • Marquise
  • Oval
  • Pear
  • Princess
  • Radiant

The shape you select really comes down to personal preference; the price doesn’t vary too much with the shape (although round diamonds tend to be a bit more costly due to market demand).

A stone’s clarity can be assessed based on the number of flaws it has, as well as the visibility of those flaws. It is generally differentiated using the following categories:

FL: Completely Flawless

As the name suggests, this stone has no flaws and is most valuable.

IF: Internally Flawless

This stone’s external flaws may be removed through extra polishing.

VVS1: Very Very Slightly Included

This stone’s flaws can only be viewed by looking at its bottom using a 10X microscope. It does not have any black marks internally.

VVS2: Very Very Slightly Included

This stone’s flaws can only be viewed by looking at its top using a 10X microscope.

VS1 – VS2: Very Slightly Included

This stone’s flaws are viewable using a 10X microscope but are not immediately obvious; they require careful detection.

SI1 – SI2: Slightly Included

This stone’s flaws are clearly visible under a 10X microscope.

I1 – I3: Included

This is the lowest clarity grade, with flaws visible with the naked eye.


Selecting carat

Finally, you’ll want to consider carat. This refers to the weight of the diamonds, not its quality, and tends to be the biggest factor in a stone’s price. 1 carat equals 200 milligrams, and this is generally subdivided into points (100 points in a carat).  So a ¾ carat stone would be a “75 point” one.
