Jewelry Design Snowflake and Venus Jewellery Collection by VDA Group Ltd. Snowflake and Venus Collection showcase the endless possibilities that come with superior stone-setting techniques and precise hand-carving skills. This design was tested more than a hundred times to reach the level of visual appeal that VDA envisioned. VDA designers created 13 different sized-diamonds, which must be precisely mounted along an intricate frame, to assemble them in a way that imitates diamonds rated at 1 carat and about yet at a significantly lower cost for the customer.
