Jewelry Designers Glossary, Part 6 - Din to Dy

Welcome to the latest edition of my jewelry designers glossary. In Part 6 we are taking a look at jewellery terms from "Din" to "Dy". The contemporary jewelry in this edition was made by members of Jewelry on Etsy (JETs) and members of Starving Artists - both teams comprise artisans specialising in designing stunning individually handcrafted jewelry. And I couldn't resist using two photos of beautiful old pieces from a couple of my favourite sources of vintage and antique jewellery here in the UK

A crystallized silicate of lime and magnesia , gem quality diopside is relatively soft and brittle and most often bottle-green in colour, although it is also found colorless, brown, black, violet-green, and blue. The two most well-known varieties of Diopside are the emerald-green Chrome Diopside and the Black Star Diopside. Chrome diopside contains chromium, which gives it a rich green colour, and is relatively soft and brittle. Violane is a rare manganese-rich variety of diopside, and is violet to light blue in colour

Black Star Diopside is an opaque stone, relatively soft and brittle, that is usually black but is occasionally green. It is unique in that is has needle-like inclusions that align to produce a white 4-rayed star asterism (see Asterism, Part 1), and sometimes needle-like surface crystalline inclusions are also visible. Black Star Diopsides are occasionally confused with Black Star Sapphires which exhibit six or twelve rays. Chrome Diopside is the variety most often seen faceted, whereas Violane is generally used for beads and inlay work. Black Star Diopside is invariably cut as a Cabochon to show the beautiful asterism present in the stone

Diva Fashion Brooch Bouquet

Also known as fire, dispersion is the prism of light refracted from within a finished diamond or stone. Technically, dispersion is the splitting of white light into its constituent spectral (rainbow) colours, when it passes through inclined surfaces such as those on a prism or faceted gem

The way a stone is cut can often determine whether dispersion (rainbow) or brilliance (white light) is more prominent so, for example, a diamond with more brilliance will show fewer flashes of colour or dispersion. Most cuts are optimized to maximize both equally wherever possible

A doublet is a layered gemstone comprising two layers cemented or glued together. Most frequently used to imitate valuable gemstones, the technique is also used with opals to create a stone from a thin vein of precious opal that would otherwise be too fragile to use. The bottom layer is usually an inexpensive mineral such as glass or a non-precious stone with the more valuable stone cemented on top. A layer of clear quartz is sometimes added to the top of a thin stone to protect its surface or to enhance its colour, and diamonds may be enlarged by cementing to a crystal base
