Like a crown caught mid-sparkle, this round lab grown diamond ring lifts the center above an expressive tiara of pear and round diamonds.
Eleven accents rise around the upper half of the center and continue onto the shoulders, creating a regal silhouette without enclosing the diamond in a conventional full halo. At twelve o’clock, a pear-shaped diamond forms the crown’s highest point and draws the eye back toward the round center.
The center is shown at approximately 3.31 ct and can be customized from 1 to 4.5 ct. The basket and surrounding accents are proportioned to suit the stone you select, then the ring is made to order in your chosen metal.
Design highlights
- Round lab grown center diamond, customizable from 1 to 4.5 ct
- Pear-shaped diamond at the apex of the tiara halo
- Ten additional round diamonds arranged through the halo and shoulders
- Approx. 0.26 ct of accent diamonds included as shown
- Four-prong center basket for an open, light-reaching presentation
- Prong-set crown silhouette with an airy, asymmetrical upper halo
- Statement-scale design with a refined high-polish band
- Made to order in 11 metal and color options
The pear diamond at twelve o’clock is the signature: it turns the arc of round accents into a true tiara, giving the ring a recognizable crown profile from the first glance.

About Lab Grown Diamonds
A round brilliant is cut with 57–58 facets engineered to return light to the eye, creating the lively sparkle that makes it the most loved engagement-ring shape. The pear-shaped crown accent carries similar brilliant faceting in a tapered silhouette, giving the tiara a distinct point of light.
Every Signora diamond is lab grown — chemically, physically and optically identical to a mined diamond and graded on the same 4C scale. The difference is origin: grown rather than mined, offering a documented source, no mining footprint and more size or clarity for the budget.
Metal, Care & Fit
Choose Sterling Silver, 9K, 14K or 18K gold in yellow, white or rose, or naturally white Platinum. The photographed ring shows a warm yellow-gold shank with a contrasting white-tone setting; a specific two-tone combination may also be requested through our custom-design service.
Order in your known ring size; most metal options can be resized. Because the center and tiara sit above the band, pair it with a curved or contoured wedding ring for the closest fit. Clean with warm water, mild soap and a soft brush, then pat dry and store separately.
FAQ
Can I choose a different center diamond size for this tiara halo ring?
Yes. Select a round center from 1 to 4.5 ct, including the approximately 3.31 ct size shown in the render. The center basket and surrounding crown are scaled to preserve the design’s proportions around your chosen diamond.
What makes this a tiara halo rather than a traditional halo?
A traditional halo usually surrounds the entire center with a continuous ring of diamonds. This design rises around the upper half like a crown, finishing with a pear-shaped diamond at twelve o’clock and leaving the lower part of the center visually open.
What is the total diamond weight of the ring shown?
The photographed configuration contains 12 diamonds weighing approximately 3.57 ct in total. That includes the approximately 3.31 ct round center and 11 pear and round accents totaling approximately 0.26 ct.
How is the large center diamond secured?
The round center sits in an elevated four-prong basket, allowing light to enter from the sides while keeping the diamond securely held at four points. The tiara and shoulder diamonds are individually prong-set to preserve their outlines and layered crown effect.
Will a straight wedding band sit flush beside this ring?
The tiara setting and side accents create a sculptural profile, so a perfectly straight band may leave a small space near the center. A curved or contoured wedding band will usually follow the crown more closely and create a fitted bridal stack.
Are the lab grown diamonds real diamonds?
Yes. Lab grown diamonds have the same carbon crystal structure, hardness and optical properties as mined diamonds, and they are assessed using the same cut, color, clarity and carat standards. They are suitable for lasting engagement jewelry and everyday wear.
