Half-Moon Lab-Grown Diamond Pairs for Side-Stone Layouts
Half-moon stones are commonly used as mirrored sides, where flat inner edges, curved shoulders, exact dimensions and center-stone fit control the result.
Request half-moon options
Drawing and seat dimensions
Provide the required length, width, flat-edge length, outer curve, ratio and CAD seat. A reference image should be supported by measurable acceptance criteria.
Mirror orientation and outline
Mark the left and right stones and compare flat inner edges, shoulder curves, symmetry, facet pattern, color and clarity relationship. The pair should be reviewed together.
Center-stone relationship
State the center shape and dimensions, side-stone angle, gap, total layout width and prong clearance. Half-moons can frame oval, round and other centers differently depending on scale.
Custom-cut tolerance and timing
If existing options do not fit the drawing, a custom-cut review can define the first-piece approval and repeat tolerance. Feasibility and lead time are confirmed in the quotation.

Request Current AvailabilityHalf-Moon sourcing questions
Are half-moons ordered by total pair weight?
State whether the target is combined or per stone, then provide the physical dimensions and center-stone relationship.
Can half-moons fit an oval center?
Yes, when the dimensions, curve, angle and CAD seats create the intended transition.
Do half-moon pairs require identical reports?
The report relationship depends on the buyer's standard. Visual and dimensional matching still needs separate review.
