It has undergone minor clarity enhancement — a permanent treatment used to reveal more brilliance without altering its natural composition. The enhancement is lifetime guaranteed and safe for daily wear.
Beauty and Value Combined
This 0.39ct stone embodies an ideal balance of size, quality, and affordability. The round brilliant cut — the most popular shape in the world — maximises sparkle through 58 precisely angled facets. Its bright white F colour allows the stone to pair beautifully with both white gold and platinum mountings, while still maintaining contrast against yellow or rose gold settings.
Whether chosen as a centre diamond for an engagement ring, part of a trilogy design, or a standalone collectible investment, this diamond represents enduring beauty and solid value. Its verified characteristics and natural origin make it an ethical, traceable, and valuable choice for any jewellery enthusiast or investor.
Detailed Description
With a carat weight of 0.39ct, this stone sits comfortably between smaller accent diamonds and more prominent solitaires, delivering excellent finger coverage without sacrificing comfort or price efficiency. The faint fluorescence contributes a subtle glow under ultraviolet light, enhancing its visual depth. The Good cut grade ensures light enters and exits through the crown for consistent sparkle, while the Very Good polish guarantees a mirror-like surface finish.
Its SI2 clarity rating means minor inclusions are present but not visible to the unaided eye, offering incredible brilliance for its value bracket. With medium girdle thickness and no culet, the structure is secure for a variety of jewellery settings — perfect for bezel, claw, or tension mounts.
Care and Cleaning Instructions
Because this diamond is clarity enhanced, certain care guidelines apply. Avoid harsh ammonia-based cleaners or ultrasonic machines. Instead, gently wash with warm water, mild soap, and a soft cloth. Never heat the diamond above 572°F. With correct care, the enhancement remains stable for life and backed by a permanent warranty.
