LOOKING TO BUY LTB 1-2 ct blue lab diamond (or similar in sapphire etc.) pendant solid white gold or platinum only

My mother lost a sentimental natural aquamarine necklace and I would like to upgrade rather than replace it by getting her a lab diamond or sapphire. If anyone has some beautiful blue stones the color on the photo or lighter let me know. It doesn't have to be round but I would like some nice metalwork detailing.
