Gemstones Guidance

A gemstone is a piece of natural occuring mineral crystal, which, after being cut or polished, is used for persoanal adornment such as jewellery.

Sometimes certain rocks (such as lapis lazuli) or organic materials that are not mineral (such as amber), are also used in jewellery making despite and therfore often referred to as gemstones as well.

Gemstones may be characteristed by their hardness (Mohs’ scale: diamonds the hardest, pearls the softest), colour or rarity.

Gemstones can be cut and polished to achieve a certain shape and luster. Faceted cuts found in round or pear shapes highlight the gemstone’s reflective qualities, while cuts such as cabochons make the stone appear softer and focuses on itscolours or inclusions.

Color enhanced diamonds such as green and blue diamonds have the beautiful shine of a colorless diamond with the added charm of mesmerizing  colours.


All colour enhanced diamonds are natural diamonds, some of nature’s most precious gifts. The exposure to electrical energy is what changes the diamonds’ color to various shades of green and blue.
