“We have more unheated goods than in previous tenders. We believe we have goods that will suit jewelry manufacturers, retailers and wholesalers” said Denning. Furthermore, for the first time at a Bonas tender, estimates on selected lots will be provided during the viewings. The indicative pricing for a number of lots will serve to create context for clients that helps them understand what the current market is.

Leading the sale is an exceptional unheated 8.88ct Kashmir ruby (Lot 456). The oval mixed-cut ruby shows no signs of heat treatment and described as pinkish-red according to the condition report from the GRS. Located in the north west of Indian Continent, Kashmir district has been known as one of the most famous localities for blue sapphire, however rubies from this region are particularly rare. Fine quality Kashmir rubies such as Lot 456 are highly valued in the market, and together with its rarity, this ruby is a notable offering of quality and distinction.

Other significant rubies should also attract plenty of attention. Two of which are of Burmese origin and certified by GRS. The first is an unheated “pigeon’s blood” ruby from the Mogok region weighing 5.22cts (Lot 308) and secondly, an attractive 8.29ct heated Burmese ruby (Lot 372). Lot 316 is a 2.99ct heart-shaped ruby of Tanzania origin, with no indications of thermal treatment according to its GRS report. This fine unenhanced natural ruby has been faceted into a heart-shaped showcasing a classic red color, with excellent clarity and lustre. Lastly, two notable unheated rubies from Mozambique are expected to attract spirited bidding given their quality. A cushion-shaped ruby weighing 5.11cts (Lot 454) with exemplary color and good clarity, and an oval cut ruby of 4.02cts (Lot 387) with a GRS report describing the color as vivid red.

The most significant Padparadscha featured in the tender includes a stunning oval shaped Padparadscha sapphire, one of the rarest varieties of sapphires named after the color of the “lotus blossom,” that features a delicate mixture of pink and orange. Unheated and weighing 23.74 carats, Padparadscha’s availability in large crystals is uncommon, making this piece (Lot 226) exceptional with its perfect mixture of color and alluring shade of pinkish orange.

Other unheated blue sapphires include Lot 59, a Burmese oval sapphire weighing 14.33cts and two of which are unheated, of Sri Lankan origin, and certified by GRS (Lots 58 & 61). Amongst blue sapphires, a fine unheated, natural purple-pink sapphire is also a star lot of the sale (Lot 285). It’s large size (12.76 cts), attractive shape and sultry purple hue combine to make this a desirable piece.

Precious Paraiba Tourmalines also figure prominently in the tender. Highly prized for its vivid glow, two neon-bright Paraiba Tourmalines of Brazil origin are accompanied by DSEF certification. Firstly, a Paraiba Tourmaline weighing 5.40cts (Lot 230) and a cushion cut Paraiba Tourmaline of 2.43cts (Lot 231), both examples would look sensational mounted as a ring or pendant.

She Wanted to Spend More Time with Her Kids. She Called Wilkerson.

Your children are precious. More precious than gold? Absolutely! Just ask Lesley Ann Davis, owner of Lesley Ann Jewels, an independent jewelry store that — until the end of 2023 — had quite a following in Houston, Texas. To spend more time with her four sons, all in high school, she decided to close her store. Luckily, she was familiar with Wilkerson and called them as soon as she knew she wanted to move on to bigger, better and more family-focused things. Was she happy with her decision? Yes, she was. Says Davis, “Any owner looking to make that life change, looking to retire, looking to close, looking for a pause in their career, I would recommend Wilkerson. Hands down!”
