  • 7.5Ct, Boulder Opal Bracelet, Tennis, Platinum On Sterling Silver, Size 7.5"

    Stunning tennis style bracelet in platinum overlay Sterling silver. This is such an unusual bracelet in style. Bracelet has 9 oval shaped natural Boulder Opals with a glorious display of colour play. Surrounding each Boulder Opal is a halo of tiny blue diamonds on what I think is a blue enamelled background. The main links to each opal are diamond cut sterling silver and containing tiny white diamonds. Each of the Opals are 8 x 6 mm and are each individual, unique in the colour play shown. Combined gem weight is 7.540 Ct. I presume that the 0.040 Ct is blue and white diamonds. This is quite a sturdy bracelet with sturdy secure fastener. Really gorgeous piece of quality jewellery. Please see my other items for other gorgeous jewellery and accessories.
