Top 5 tips from the industry’s leading gemologist and diamond dealer


Find your perfect diamond

Would you ever buy a house or a car without consulting an expert first? Today, it is quite common to obtain qualified advice or a ‘second opinion’ from an independent gemologist and diamond expert before choosing to invest a fortune in either an engagement ring, a diamond bracelet, a set of diamond earrings or a rare yellow, pink, or blue diamond.

In the following section, diamond dealer and gemologist Sidsel Dalby gives 5 good advice on how you as a consumer can get the best diamond within your budget on an opaque market.

Can you see the difference? Both diamonds are 1.00 carat / each, but one costs USD 3,550 more than the other.

1. Brilliant cut diamond 1.00 Carat I SI1 GIA Certificate. USD 7,680

2. Brilliant cut diamond 1.00 Carat G/Top Wesselton VS2 GIA Certificate. USD 11,230

The 4 Cs

Tip #1

GIA made the first and now globally accepted standard description of diamonds: Color, Clarity, Cut and Carat Weight. White or colorless diamonds are valued on the basis of the 4 Cs, where it is different with Fancy Color Diamonds, including i.a. yellow, blue and pink diamonds. Here, it is the color composition and intensity of the color that primarily determines the value.

If you are looking for a classic white diamond ring for an engagement with a limited budget, it can pay off:

  • To go for a slightly lower color / clarity if you want to round the magic 1.00 carat. The untrained eye will not be able to see the difference between, for example, a G / H color, which is why it pays to compromise here.
  • 5-10% of all diamonds in a lower clarity like SI are ‘eye clean’, ie. one does not see inclusions for the naked eye. One should therefore ally with an expert who has access to the few stones that are found within the category.

With the above you get more ‘carat’ for your money

Fancy Shaped Diamonds

Tip # 2

Did you know that diamonds come in several different shapes (and colors)? You can choose to go for a design where the diamond in the earrings or ring is for example in a cushion cut rather than a classic round brilliant cut. Or maybe an emerald cut, which is quite popular among celebrities and royalty.

You usually get more carats for the money by choosing fancy shaped diamonds over the classic round cut, as more waste occurs during the preparation from rough diamond to a round polished diamond. At the same time, the advantage of fancy shape diamonds is that they often dress the hand, appear visually larger compared to a round diamond and make the hands look slim and long. An alternative is also to combine the classic white diamonds with a colored diamond, where especially the yellow diamonds are highly sought after.


Tip #3

There is great science associated with cutting and grinding a rough diamond directly from the mine. Grinding refers to the proportions of a diamond and the quality of its skill. The beauty of a diamond lies in its complex relationship to the light, where a perfectly cut diamond captures the light in a special way and makes it sparkling and radiant. Grinding also refers to the shape and faceting of a diamond with round, emerald, princess, pear, marquise, and cushion grinding etc.

The important thing is to focus on the cut in the stone / the diamond cut – here it pays to choose an excellent cut or at least a very good cut, where the light reflects the diamond optimally and the coveted ‘sparkle’ is seen in the stone. A diamond with a bad cut will be dull and unattractive to look at without shine.
