Oval Labradorite. Labradorite gets its name from Labrador in Canada, where it was first “discovered”. The gemstone is a type of feldspar, a commonly occurring group of minerals; the much-loved Moonstone is another type of feldspar, and the above Oval Labradorite, with its colourless translucence and shimmering blue tone, is often called a “Blue Moonstone”.
The most commonly found Labradorite is opaque, with greens and purples and blues, the colours shimmering vividly, especially when polished, in an iridescent effect called labradorescence. This type of more commonly found Labradorite is more an “ornamental” gemstone and is rarely used in jewellery. The “Blue Moonstone” type of the above Oval Labradorite, however, has often used been in rings and pendants of Silver since the early 1900s.
The above Silver setting is completely handmade, very solid, a pleasant weight at just on 12 grams.

Note: the band is a uniform 7.6mm in width, domed to a depth, or thickness, of just on 2.5mm. The ring can definitely be re-sized but would require some genuine bench skill to properly effect.
