18k Yellow Gold 1.59ct Lab-grown Marquise Diamond 6 Prong Solitaire Engagement Ring

Command attention with this striking 1.59 carat lab-grown marquise-cut diamond solitaire engagement ring. The elongated marquise cut, known for its elegant silhouette and dazzling brilliance, creates a graceful, lenghtening effect on the finger. Set in a refined six-prong solitaire setting, this timeless design lets the diamond take center stage.

The center diamond, ethically grown and graded D for colour and VVS2 for clarity, radiates exceptional fire and purity. Its crisp, colourless body and eye-clean clarity make it an extraordinary choice for those who value both sophistication and sustainability.

Crafted from premium 18k yellow gold, the warm-toned band beautifully contrasts the icy brilliance of the diamond, enhancing its natural sparkle. The six-prong setting adds a secure and balanced finish, allowing light to flood through the stone for maximum brilliance.
