Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow, drawing the eye along its tapered points. This semi-set platinum mounting awaits your choice of a 10 x 5 mm center stone, designed with subtle accent details that enhance the diamond’s dramatic shape without overwhelming it.

Crafted in platinum for durability and a cool, luminous finish, the setting features a low-profile design that sits close to the finger, ensuring comfort for everyday wear. The secure prong arrangement balances protection with visibility, allowing the marquise’s unique geometry to command attention while maintaining a sleek silhouette.

Each piece reflects our commitment to ethical jewelry through lab-grown diamonds, offering clarity and sparkle with a smaller environmental footprint. The mounting’s refined proportions suit hands that appreciate architectural elegance and a confident, modern statement.

Its slim band and modest height make this ring glove-friendly and ideal for stacking alongside wedding bands or other fine jewelry. Resizing is available to ensure a precise fit, crafted with the same care as the original design.
