Marquise Green Lab Grown Diamond Three Stone Pavé Ring

The Side Pears Should Transition the Marquise, Not Compete With It

FLGR-08 is built around a 1.00 carat Fancy Vivid Green marquise lab-grown diamond. A matched pear-shaped diamond sits on each side, followed by a narrow diamond-set shoulder in 18K white gold. The result is not a halo and not a plain solitaire: the two pears act as the visual bridge between the long center stone and the slim shank.

For a B2B order, that transition is the part worth controlling. If the side pears are too broad, the ring loses the elongated marquise character. If they are too small or sit too low, the center looks isolated from the shoulders. The approved sample should therefore record the face-up relationship between all three principal stones, not only their combined weight.

Start With the 1.89 Marquise Ratio

IGI report LG678599800 identifies the center as a 1.00 ct Marquise Modified Brilliant measuring 9.07 x 4.79 x 3.22 mm. Its length-to-width ratio is approximately 1.89, which gives this sample a distinctly elongated center outline.

The diamond is graded Fancy Vivid Green and VS1, with Very Good polish, Excellent symmetry and no fluorescence. The report records CVD growth and indications of post-growth treatment.

These grading facts apply to the inscribed center diamond. They do not grade the approximately 0.52 ct of accent diamonds or certify the finished 18K white gold mounting. If another marquise is selected, its actual length, width, depth and point positions should be checked before the side-stone seats are copied.

Pair the Side Pears by Outline Before Carat Weight

The two visible pear side stones should be treated as a matched pair. Compare their length, width, lobe fullness, point length and face-up orientation before they are released to setting. Equal weight alone does not guarantee that the left and right sides will look balanced beside a narrow marquise.

The inward-facing ends should meet the center at comparable distances, while the outer curves should hand off smoothly to the smaller shoulder diamonds. This is especially important in repeat orders, where a new side pair may technically fit the setting but still change the ring's face-up spread.

For related colored center options, the Lab Green Diamond Ring collection provides the closest finished-jewelry comparison. This model should remain the marquise-and-pear three-stone route rather than borrowing halo or convertible-ring positioning from other pages.

Approve Three Widths in CAD

Instead of describing this ring only as a “three-stone style,” record three measurable widths in the production file:

1. Center width: the face-up width of the marquise at its widest point.
2. Three-stone span: the total visible width from the outside of one pear to the outside of the other.
3. Shoulder width: the width where the smaller diamond-set shank begins after the side pears.

These three numbers make it easier to scale the concept for another center size without simply enlarging every component by the same percentage. They also give a private-label buyer a practical way to define finger coverage before the first sample is produced.

If the target spread needs to change, use the custom ring CAD process to adjust the side-pear dimensions and shoulder taper together. Changing only one pair of stones can disturb the center-to-shank transition.

Do Not Treat the 0.52ct Accent Total as One Parcel

The sample records approximately 0.52 ct of accent diamonds. Visually, that total serves two different areas: the two principal pear side stones and the smaller diamonds set along the upper shoulders. Those groups should be listed separately in the repeat-order stone schedule.

This separation matters when a buyer wants to keep the same three-stone face while changing ring size or shoulder coverage. The pear pair can remain visually fixed while the melee count is recalculated for the revised shank.

QC the Transitions, Not Only the Stone Centers

A front-view QC image should confirm that the marquise runs on the ring centerline, both pear side stones mirror each other in height and angle, and the shoulder diamonds begin at comparable positions. The two marquise tips should also show even protection and clearance.

An angled QC image should check that the side pears do not sit noticeably above or below one another and that their prongs do not crowd the center setting. Keep both views with the approved three-stone span and sample weight for repeat production.

Questions Buyers Should Resolve Before Sampling

Can the pear side stones be enlarged without changing the marquise?

Yes, within a redesigned shoulder transition. Larger pears increase the total face-up span and may require new seats, different prong positions and a wider connection to the shank.

Can another 1.00ct marquise use the same side-stone layout?

Only after comparing its actual millimeter dimensions and point positions. Two marquise diamonds of the same weight can have different ratios, which changes the gap and angle beside the pear stones.

What should be fixed for a repeat private-label order?

Keep the approved center dimensions, pear-pair measurements, three-stone face-up span, shoulder width, ring size, sample weight and front/angled QC images with the order record.

Start the inquiry with the width you want the customer to see. In the FLGR-08 development request, send the target ring size, center preference and either a desired three-stone face-up span or a wearing reference. The first CAD can then balance the pear pair and shoulder taper around a defined visual width instead of copying a generic three-stone template.
