0.90 Ct.Tw.Total Carat Weight Ruby Pair from Thailand

This matched pair comprises a 0.41 ct ruby and a 0.49 ct ruby, both cut to a round outline with mixed brilliant facet architecture, with dimensions of 4.39 x 4.38 x 2.47 mm and 4.37 x 4.31 x 2.98 mm respectively. The mixed brilliant cut combines a brilliant crown with a faceted pavilion profile optimized to retain weight while promoting crown dispersion, and these examples exhibit an excellent polish that produces clean facet junctions and crisp light return. Clarity is graded as very slightly included, evaluated at eye level, which indicates small natural inclusions that do not impede overall transparency or diminish the vivid color intensity, a key attribute of these Thai origin rubies. Both stones have been heat treated, a stable and internationally accepted enhancement that deepens hue and clarifies internal silk without compromising structural integrity. Measured proportions show a shallower profile in the 2.47 mm depth piece and a deeper pavilion in the 2.98 mm depth piece, yielding slight differences in face up spread and light distribution, yet the near equal girdle diameters maintain visual symmetry for paired mounting.

In a halo setting these technical attributes translate into exceptional visual performance, The Natural Ruby Company recommends settings that exploit contrast and light capture. A fine white metal halo will introduce high contrast reflection against the vivid red, enhancing perceived saturation and scintillation from the mixed brilliant crown facets, while a warm gold halo will reinforce the stones natural warmth for a richer overall tone. The halo of small melee should be selected with consistent diameter and low profile millgrain or shared prong mounting to preserve crown visibility and allow unobstructed light entry into the pavilion facets. Because the stones differ slightly in pavilion depth, a halo design serves to equalize apparent diameter and silhouette, masking depth variance while amplifying sparkle through multiple small reflectors. For maximum brilliance choose minimal prong coverage at the table and slightly elevated halo spacing to permit internal reflections to interact with the surrounding melee, this produces a lively, fiery presentation ideal for rings, studs, or clustered pendants. These rubies combine technical refinement and natural color intensity, and mounted in a considered halo they will command attention through precise contrast, engineered light return, and harmonious proportions.
