Signora Jewels sets the 6.50 mm heart between two 3.75 mm trillion diamonds, turning each triangle toward the center so the three outlines meet without looking crowded. The heart sits point-down, with prongs guarding its cleft, shoulders and tip.
The trillion stones pull the line outward before it meets the plain shank. Their sharp corners and brilliant facets throw quicker flashes beside the broader face of the heart.
All three diamonds sit in open baskets above the band. That leaves room beneath the stones for cleaning, while the polished lower shank stays smooth against the palm.

About Lab Grown Diamonds
A heart cut combines a cleft crown, rounded lobes and a pointed base. The trillion side stones use triangular brilliant faceting, producing smaller flashes that lead away from the center.
Lab grown diamonds have the same carbon crystal structure, hardness and optical properties as mined diamonds. They are graded using the same cut, color, clarity and carat standards.
Metal, Care & Fit
Choose silver, 9K/14K/18K gold in yellow, white or rose, or platinum. 9K has more strengthening alloy, while 18K contains more gold and carries richer color; compare them in the metal guide.
Order in your known US size. The three stones spread farther across the finger than a solitaire, so an accurate fit helps keep the heart upright; use the ring size and fit guide. Clean beneath each basket with warm water, mild soap and a soft brush.
FAQ
Is the center diamond included?
Yes. The ring includes one fixed 1.000 ct heart Lab Grown Diamond measuring approximately 6.50 × 6.50 mm.
What is the total diamond weight?
The ring contains approximately 1.390 ct across three diamonds. That total combines the 1.000 ct heart center with two trillion side stones totaling approximately 0.390 ct.
How are the side diamonds positioned?
One trillion diamond sits on each side of the heart with its point directed toward the center. The broad outer edges step into the plain tapered shoulders.
How is the heart diamond protected?
Prongs secure the heart around its upper lobes, sides and pointed tip. The tip receives direct metal protection because it is the most exposed part of the outline.
Will a wedding band sit beside this ring?
A straight wedding band sits close beneath the raised three-stone gallery. A slight gap can remain near the side baskets, while a gently contoured band follows the setting more closely.
How does a heart cut compare with a round diamond?
A heart cut has two rounded lobes, a central cleft and a pointed base, while a round diamond has one continuous circular edge. The heart outline gives this ring a more directional face-up shape.
What is the difference between 9K and 18K gold?
9K gold contains more strengthening alloy and has a harder surface, while 18K contains more gold and carries richer color. Signora Jewels makes this ring in both, along with 14K gold, silver and platinum.
