Carat (ct) is the standard unit used to measure a gemstone’s weight. One carat equals 200 milligrams. Carat refers to weight, not size, so gemstones of the same carat weight can appear different in size depending on their cut and type.

Gemstone cuts in jewelry are all about maximizing a stone's natural beauty and brilliance. The shape and facets are carefully crafted to enhance its color, clarity, and sparkle.

A gemstone’s cut starts from raw, rough crystals that gem cutters analyze and shape, considering things like its size, shape, and how light will interact with it to create the perfect sparkle.

Diamond clarity describes the presence or absence of internal imperfections (inclusions) and surface flaws (blemishes) within a diamond. These natural characteristics form during the diamond’s creation and are graded on a scale ranging from Flawless to Included.

Higher clarity means fewer or less visible imperfections, which can affect a diamond’s brilliance and value.

The gold fineness determines the content of pure gold in the alloy used to make jewellery.

• 14K (585) – 58.5% pure gold, warm colour, good balance of hardness and plasticity.
• 9K (375) – lighter shade, greater hardness due to higher alloy content.
• 8K (333) – most subdued colour, highest mechanical resistance.

Fineness of 585 or 14K is the perfect balance between price and quality.
