The Round Brilliant Diamond Necklace Holy Trinity was originally inspired by a request from a friend who wished to wear three half-carat round brilliant diamonds, symbolizing her husband and two children. I loved the concept so much that I created one for myself as well. This piece exudes an alluring yet elegant charm, making it perfect for both day and evening wear. The small plate can be customized with a personal engraving – I always enjoy adding that special, personal touch. We offer this necklace with three 0.50ct round brilliant diamonds (including GIA certificates), for a total carat weight of 1.50ct. For a slightly smaller version, we offer an equally delightful design featuring three 0.30ct round brilliants (also with GIA certificates), totaling 0.90ct. If you have a different carat weight in mind, simply send us a message, and we'll be happy to accommodate your request.
