On Wednesday the 21st of June Roseberys are thrilled to present a strong sale of over 400 lots covering jewellery from the 18th century to the present day - with a very good selection of large diamonds and gemstones - as well as collections of pens and watches. Diamonds are a prominent feature of this month’s auction, and the sale culminates with an exceptional highlight in Lot 443; a stunning round brilliant-cut diamond single stone ring of 6.09 carats. Set between radiating baguette diamond shoulders, the diamond is accompanied by a report confirming that it is graded as G colour and VVS2 clarity.

Lot 440: A sapphire and diamond pendant, claw set with an oval mixed-cut sapphire

The sale also presents a number of impressive sapphires likely to appeal to those who collect, or simply appreciate for their rarity and alluring colour. Lot 440 is a sapphire and diamond pendant featuring a dazzlingly saturated blue Sri Lankan sapphire weighing 24.13 carats. The oval mixed-cut stone is accompanied by a laboratory report stating that no heat treatment had been detected. Sapphires of such gem quality that have not been heated to improve colour are rare. Lot 439 is an elegant pair of sapphire and diamond ear clips, in which each sapphire weighs approximately 9.0 carats. They are of a beautiful well-matched ‘Ceylon’ colour with good transparency and life. These ear clips also include a lab report stating that no heat colour enhancement had been detected. Lot 442 is a single sapphire ring of approximately 10 carats with a reported origin of Burma, the second most important locality for sapphires after Kashmir.

Lot 438: A rare Melo melo pearl and diamond ring

Several beautiful pearl pieces are sure to garner great interest from collectors, including lot 438, a rare Melo Melo pearl and diamond cluster ring. Melo Melo pearls (also known as Dragon Pearls) are believed to be the rarest in the world and cannot be cultured. They take at least a decade to form and are composed not of nacre, but calcite and aragonite, which gives the pearls their characteristic ‘flame’ and porcelain appearance. Another pearl highlight is lot 430, a pair of early 19th century diamond and natural pearl pendant earrings, dating to around 1820. The pearls in these earrings have a lovely lustre are well-matched and beautifully set off with old -mine and rose-cut diamonds.
