Quality & details


Rosing only uses the best goldsmithing materials, which primarily include gold and silver, natural diamonds, cultured pearls and natural gemstones. Through generations in the fine jewellery business, we have established a professional network of suppliers, which we treasure, ensuring that we have first-pick in quality.


No two diamonds are alike. Diamonds were formed deep below the earth’s crust millions and billions of years ago, under the most extreme conditions. For the same reason, diamonds are considered the most rare and precious of all gemstones.

When cutting a diamond, magic happens – and it is also the only stage of the process where mankind exerts any power over diamonds. Everything else is determined by Nature itself.

Carat weight
The weight of a diamond is measured in carats. One carat equals 0,20 grams.

The colour of diamonds is graded on a scale from the letter D (colourless) to Z (light yellow or brown).

The diamonds set on Rosing jewels are all hand-selected, and only the very best make it through our selection process. We place our trust in diamonds certified by the HRD (Hoge Raad voor Diamant) and the GIA (Gemological Institute of America).

The colour, clarity and size of diamonds are predetermined by Nature. Only the cut depends on the talent and expertise of a diamond-cutter. For the very same reason, the cut of a diamond is a crucial quality factor in the four C’s grading system. Exemplary cutting of a rough diamond can turn the gemstone into an exceptional masterpiece.

A perfectly cut diamond needs to fulfil certain criteria, such as symmetry, proportions, overall height and table size. Diamonds, which are not brilliant cut, are known as ”fancy cuts” – baquette, princess cut, heart cut, cushion cut, pear cut and several more.

Inclusions are natural imperfections in a diamond, which can affect the diamonds clarity when it is cut. The number, size, colour, relative location, orientation, and visibility of inclusions can all affect the relative clarity of a diamond. Diamonds are graded for clarity under 10 x loupe magnification from FL (flawless) to I3 / P3 (included, numerous inclusions visible to the naked eye).

As gemstones originating in Nature, few diamonds attain the grade of flawless.

The love diamonds
Hearts & Arrows and Rosing

Only the best quality and most beautiful diamonds are selected to become love diamonds.

A number of Rosing rings are set with a brilliant-cut diamond with the “Hearts & Arrows” cut, where, if you look closely, you can discern eight hearts and eight arrows in the gemstone.

Fine cultured pearls
are rare and in great demand. Rosing only buys cultured pearls from trusted suppliers in order to guarantee the high quality.

With a contemporary view of the cultured pearl in mind, Kristina Rosing has a definite take on how cultured pearls should be worn. The expression is deliberately conceptualized to blend in with everyday clothing, in order to ensure maximum wear. Diamonds may provide an eternal glamour, but cultured pearls ensure that pieces are both gracious and inviting for a woman to adorn herself with. The cultured pearl look might be one of the classics, the quiet chic needed in every woman’s jewellery box – but there is also the option of donning cultured pearls with a little more razzle dazzle.

South Sea cultured pearls are the queen of pearls – rare, large and breathtakingly beautiful; they are found in feminine shades of white, silver, rose, light yellow and golden. Tahiti cultured pearls represent the dark colours of the colour spectrum with shades of blue, green, metallic, and grey. In size, they range from 8-16 mm and in some cases up to 20 mm. Like diamonds, cultured pearls are also graded on size and colour, but the value of cultured pearls is primarily based on lustre and shape.


Each Rosing piece is under a five years warranty, issued at the date of sale. Rosing provides care, repair, and complimentary polishing of the precious metals.


Rosing recommends that jewellery is the last you put on before leaving your home, and the first you remove again when you get back. Remove your jewellery before partaking in sport activities and before bedtime. Store the jewellery in jewellery boxes with separate compartments or small pouches made of cloth, so that individual pieces of jewellery do not scratch others by accident, or chains get tangled up.

Bracelets and rings are the ones most subjected to blows, which may loosen the settings of cultured pearls and gemstones. We recommend that your diamond jewellery is checked and cleaned at least once a year, depending on how often the jewel is worn. When handed in for a check, all prongs and other settings are looked over, to ensure that they are intact, and that the diamonds and other gemstones are held securely in place. Remember that it can also be sensible to have necklaces made of precious metal (chains, links and the like) looked after to protect against breakage. The annual check is recommended in order to ensure the continued stability of the setting of the gemstones and the elegance and wear-ability of the pieces.

Cultured pearls should always be whipped off with a clean, soft cloth before being put away. Remember that especially cultured pearls benefit from being worn.

Diamonds benefit from an ultrasonic clean – we are happy to do this for you. With proper care, your Rosing jewels will retain their beauty and character for generations to come.
