April birth stone: Diamond


White diamonds in various cuts and shapes. From the left to right, princess square, round brilliant, marquise, pear, radiant, emerald, heart and asscher.

April’s diamond is diamond. Diamond is a girl’s best friend. I love diamond and everyone loves diamond (although I know one person who said she hated diamond).

So here is some non-technical, non-gemmological chit-chat about diamond.

Diamond is the one of the hardest materials on the earth.

It is said to be the oldest substance ever created since the birth of the earth.

Solitaire engagement rings with round brilliant diamonds are the most sold fine jewellery category in the world.

Some people do purchase diamond as an investable asset. In our opinion, you need to buy exceptional stones, such as very large ones, flawless or rare natural coloured diamonds, to be able to returns by buying them now and selling later. IKURIA can source exceptional stones.

We always think it is the best to buy stones you want to wear.

Stick with so-called the “4Cs” of diamond grading. They are colour, cut, clarity and carat weight. 

We, IKURIA, like diamond for engagement rings, along with sapphire and ruby, due to its hardness, durability, eternal brilliance.

Above are the well-known facts.

Here are some of the things we discuss with customers face-to-face.

Regarding carat weight, there are some magic numbers. As soon as the carat weight hits 0.5, 1.0, 1.5 etc., price per carat jumps up. So we often recommend diamonds weighing just under these magic numbers, such as 0.48 carat, 1.87 carats, as it is more economical to buy and they look pretty much the same as the ones weighing magic numbers.

We can think beyond 4Cs.  We love unusual diamonds. While cushion cuts are gaining popularity recently, some of our customers love asscher cuts, rose cuts and very sleek emerald cuts. Others love rustic stones such as rough cut diamonds, grey diamonds and unclear diamonds.

We can think beyond engagement rings. Diamonds look brilliant anywhere. We have made dress rings, necklaces, earrings – really anything.
