Blue Sky Spark — 3.09ct Oval Lab Diamond Platinum Ring

The Blue Sky Spark is a 3.09ct oval lab grown diamond platinum ring, part of a series where a single colour becomes the personal identity of the design. This one takes its colour from exactly what its name suggests: a clear, vivid blue, set to catch and hold the light around a single central stone. At its centre sits a 3.09ct oval lab diamond, D colour, VVS2 clarity, IGI certified. It is graded Excellent polish and Excellent symmetry and measures 11.67 x 8.14 x 5.18 mm Either side, two round vibrant blue lab diamonds - four in total (0.26ct combined) provide the stylish flash of colour, finished by a round white lab diamond on either side where the setting meets the shank (0.13ct combined). Total diamond weight: 3.48ct. Set in 950 platinum, hallmarked, and carrying Christine Sadler's own sponsor's mark as a signature of authenticity. Like every piece in the Spark series, the Blue Sky Spark exists once. When it sells, it joins The Archive — its design becomes the starting point for a future commission, but this exact ring will never be made again. This is a ring that will only belong to one lucky lady to treasure and pass on one day.
