From aquamarine to tourmaline and all colours in between, the Fine Jewellery, Watches and Silver Sale on 13th July offers up coloured gemstones aplenty.
Aquamarine and Diamond Pendant
Alongside the excellent offering of substantial diamonds covered in our previous blog, we have all colours in the gemmology spectrum waiting to go under the hammer. To focus on a few; lot 2262 is a very attractive Aquamarine and Diamond Pendant. Converted from an Art Deco brooch, this stylish piece carries an estimate of £2,000-3,000 and is arguably much more wearable in its current form than it would have been when double the size, as a clip or brooch (all figures exclude buyer’s premium).
Pendant on Chain by Hirsh of London
Also in blue neckwear is lot 2273 the superb quality Pendant on Chain by Hirsh of London, set with vibrant blue sapphires formed in a cluster, in a geometric arrangement. This is estimated at £800-1,200, but previously lots from this desirable jewellery house have been strongly competed for.
A Tanzanite and Diamond Ring
Moving over to a purple hue is lot 2245, A Tanzanite and Diamond Ring. The trilliant cut is not commonly seen in gemstones, but tanzanite leads the way, as this cut exemplifies the trichoic nature of the stone. This is mounted over a diamond set band and with an estimate of £1,200-1,800 we anticipate lots of competition.
Pink Tourmaline, Emerald and Diamond Pendant on Chain, by Catherine Best
The jewellery section begins with lot 2179, which is a Pink Tourmaline, Emerald and Diamond Pendant on Chain, by Catherine Best. A stunning shade, the design of this pendant sets the principal gemstone off with style. It is estimated at £700-1,000.
Diamond Floral Spray Brooch
Also adding a splash of red is lot 2219. The Diamond Floral Spray Brooch uses rubies as an accent, to great effect. This lot has an estimate of £500-700.
18 Carat Gold Red Spinel and Diamond Ring
Probably the most famous red spinel is that which sits over the Cullinan II diamond in the Imperial State Crown. Believed to be a ruby for hundreds of years, it is now known to be a red spinel. Comparatively more modest, but enchanting nevertheless is the red spinel in lot 2188, an 18 Carat Gold Red Spinel and Diamond Ring. Red spinel is still quite rare in jewellery terms, and as such can be very sought after. This contemporary ring is estimated at £3,000-5,000.
Citrine and Diamond Cluster Ring
Yellow can be found in lot 2268, a Citrine and Diamond Cluster Ring estimated at £600-800. Part of the quartz family, citrine remains a popular choice for a yellow gem.
Emerald and Diamond Ring
Finally, something green. Lot 2305 is an impressive Emerald and Diamond Ring, consigned at one of our external valuation events in the North West. This superb example of an Art Deco ring carries an estimate of £5,000-7,000. Since consignment, it has been checked at a reputable laboratory that gave the opinion of Colombian origin, generally regarded as the source of the finest emeralds in the world.
