Pearl – Pearls are organic gems, created when an oyster covers a foreign object with beautiful layers of nacre. Pearls are among the most beautiful gemstones in existence, being prized for their iridescent sheen. The quality of pearls is judged by the orient, which is the soft iridescence caused by the refraction of light by the layers of nacre, and lustre, the reflectivity and shine of the surface. Fine pearls do not have any flaws or spots in the nacre: it has an even, smooth texture. Other factors which affect value are the regularity of the shape, size, and colour: rose tints are the most favoured. Cultured and natural pearls can be distinguished from imitation ones by a very simple test. Take the pearl and rub it (gently!) against the edge of a tooth. Cultured and natural pearls will feel slightly rough, like fine sandpaper, because of the texture of natural nacre. Imitations will feel as smooth as glass because the surface is moulded or painted on a smooth bead. They come in a range of colours, including white, yellow, cream, brown, black, and grey. Birthstone for June.

Citrine – Citrine collars range from light yellow to dark orange and brown. However, high-quality citrine gems have an intense golden hue, with fiery orange flashes inside.
