These platinum diamond stud earrings feature a matched pair of princess-cut diamonds with a combined total carat weight of 1.40 CTW. Set in solid platinum (950 or 900 platinum), they offer exceptional durability and a bright white metal that complements the natural brilliance of the stones.
The diamonds are graded VS2 in clarity, meaning inclusions are minor and difficult to detect even under 10x magnification, ensuring a clean, sparkling appearance to the naked eye. The I color grade falls in the near-colorless range, offering excellent value while appearing white in a platinum setting. Princess cut diamonds are renowned for their square silhouette and faceting pattern, which maximizes brilliance and fire.
Each earring is secured with a Guardian-style back, a screw-back or locking mechanism designed to prevent accidental loss โ an important feature for high-value fine jewelry. The pair is sold as a set and is suitable for everyday wear or special occasions.
