Description
Classic brilliance meets detailed vintage character in this 2.50TCW Round Lab Grown Diamond Vintage Engagement Ring by Unii Jewels.
The design is centered around a substantial 2.00CT Round Lab Grown Diamond, offered in the D-E-F color range and VVS-VS clarity range, with an Excellent cut and IGI certification. The symmetrical Round silhouette creates a timeless focal point, while its brilliant-style appearance makes it especially suited to a design built around sparkle.
Complementing the center are Round Lab Grown Diamond side stones totaling 0.50TCW, also offered in the D-E-F color and VVS-VS clarity ranges.
Together, the 2.00CT center diamond + 0.50TCW Round side diamonds create an accurate total diamond weight of 2.50TCW.
The combination of a substantial Round center, matching Round accents, vintage styling and a refined 2MM band creates a cohesive engagement-ring design with brilliance extending beyond the center stone.

The Design Story — Round Brilliance with Vintage Character
This engagement ring uses the timeless symmetry of Round diamonds throughout its composition.
The 2.00CT Round center diamond establishes the primary focal point, while 0.50TCW of Round side diamonds extends the brilliance into the surrounding vintage design.
Because the center and accent stones share the same shape, the ring maintains a visually coordinated diamond language:
2.00CT Round Center → 0.50TCW Round Accents → Vintage Styling → 2MM Band
The difference in diamond size establishes hierarchy without requiring contrasting stone shapes.
Why the 2.00CT Round Diamond Stands Out
The center stone represents 80% of the complete 2.50TCW diamond weight, while the side diamonds account for the remaining 20%.
This creates a strong center-focused composition.
At 2.00CT, the main Round diamond provides substantial visual presence while remaining proportionally balanced with the 0.50TCW of surrounding diamonds.
Its supplied specifications include:
D-E-F Color Range
VVS-VS Clarity Range
Excellent Cut
IGI Certification
0.50TCW Round Side Diamonds
The supporting Round diamonds contribute a meaningful 0.50TCW to the design.
Rather than functioning as extremely minimal accents, they provide enough combined diamond weight to extend visible brilliance around the center stone.
Their matching Round shape also creates continuity between the center and surrounding diamond arrangement.
Round-on-Round Diamond Design
Using Round diamonds for both the main and side stones creates a highly consistent visual composition.
Instead of introducing different outlines, the design repeats the same circular diamond geometry at different scales.
This creates:
Large Round Center → Smaller Round Diamonds → Vintage Detail
The visual transition from center to accents remains smooth and cohesive.
Vintage Engagement Ring Character
The supplied Vintage styling gives the ring a more detailed identity than a plain Round solitaire.
The Round accent diamonds add decorative brilliance while keeping the center diamond dominant.
This combination makes the design suitable for customers looking for the timeless appeal of a Round center diamond with additional vintage-inspired detail.
D-E-F Color & VVS-VS Clarity
Both the center and side diamonds are offered within the supplied:
D-E-F Color Range
VVS-VS Clarity Range
The 2.00CT center Round diamond additionally features an Excellent cut and IGI certification.
This creates a coordinated specification profile across the complete diamond arrangement.
Why the 2MM Band Works
The 2MM band width provides a refined foundation for the 2.50TCW composition.
It keeps the overall ring profile elegant while allowing the center and supporting diamonds to remain visually prominent.
The design hierarchy stays clear:
2MM Band → Vintage Details → Round Side Diamonds → 2.00CT Round Center
Metal Customization
This ring can be created in:
