1.51 Ct. Ruby from Mozambique

If you are searching for a single gem that ends your quest for the ideal center stone for an engagement ring or a standout component for a bespoke jewelry commission, this Mozambique ruby from The Natural Ruby Company is a perfect solution. Many clients come to us wanting a stone that balances immediate visual impact with the practical realities of forging a lasting piece. You want a ruby that reads as vivid and alive when worn, that sits comfortably and proportionately on a ring or pendant, and that adapts easily to the varied design directions you might consider. This round 1.51 carat ruby delivers that balance, combining a classic silhouette with the size that reads boldly as a solitaire, but still fits harmoniously into halo, three stone, or delicate cluster designs. The clarity, polish, and cut work together to produce a face up presence that will satisfy both a romantic expectation and a maker's requirement for a gem that behaves predictably under light and in settings.

Technically the gem is a transparent round shape weighing 1.51 carats with dimensions of 6.34 x 6.27 x 4.26 mm, cut in a mixed brilliant style to optimize both scintillation and depth of color. The clarity grade is very slightly included evaluated at eye level which means that the stone reads very clean to the eye with only minimal internal characteristics when inspected closely. Color is the jewel's story, and this ruby shows a vivid intensity that reads rich and saturated in both direct and ambient light. The polish is excellent which ensures crisp facet junctions and smooth surfaces that return light efficiently. The ruby has been heat treated a common and accepted enhancement in the trade that enhances the stone's clarity and color without detracting from its natural beauty. Origin is Mozambique, a source known for producing rubies with deep, warm tones and good crystal transparency. Taken together these factors make this stone an exceptionally practical and beautiful choice for custom work because you are getting predictable face up color the kind of optical performance a designer can build around and dimensions that suit a wide range of mounting styles.

From a design perspective the round shape and the roughly 6.3 mm diameter make this ruby one of the most versatile starting points you can choose for custom jewelry. For an engagement ring the size reads like a confident statement on the hand without being oversized, and the round geometry allows for perfect symmetry in prong mountings, low profile bezels, and more elaborate vintage inspired settings. The mixed brilliant cut gives lively sparkle on the crown and retains depth in the pavilion that helps the color appear saturated at the table, which is particularly desirable when pairing the ruby with white diamonds in a halo or side stone configuration. If you prefer warmer metal tones the vivid red will sing in yellow or rose gold while white gold or platinum will accentuate contrast and sparkle. Because the stone is essentially eye clean the designer does not need to overcompensate with heavy settings to conceal inclusions, which allows for more elegant, less obstructive mounting choices that let the ruby remain the visual hero of the piece. For necklaces and pendants the diameter is ideal for a single drop that moves freely and becomes a focal point without overwhelming the neckline, and for custom earrings matched pairs are easily approximated using similar size stones from our inventory if you wish to expand a suite.

When you commission a custom piece from The Natural Ruby Company you are not only purchasing a singular Mozambique ruby with excellent polish and vivid color, you are accessing our expertise in placing that gem into designs that maximize its strengths. We will advise on prong profiles that protect the girdle while allowing maximum table exposure, on bezel wall heights that preserve the face up color, and on complementary stone choices that will enhance rather than compete with the ruby. If you are creating an engagement ring we can show you proportions that flatter different finger shapes and lifestyles, and if you are designing a pendant or brooch we can arrange the setting to ensure light enters the stone for optimal brilliance. This ruby's size and round format reduce fabrication complexity and keep production timelines efficient, while its eye level clarity and vivid saturation reduce the need for heavy metalwork that can hide the gem.
