Description

This untreated Ruby Pair from Johnson, Tanzania features two elegant oval cabochons in a 9 x 7 mm size and displays an attractive pinkish red color. Well matched in shape and overall appearance, this pair is especially suitable for jewelry designs that require balance, harmony, and the unmistakable character of natural ruby.

Pinkish red color with lively elegance
The pair shows a pleasing pinkish red color that gives the stones a bright and refined appearance. This tone offers a slightly softer and fresher interpretation of ruby color while still preserving the classic charm and desirability associated with natural ruby. In cabochon form, the color is presented smoothly across the curved surface, giving the stones a rich and elegant look.

Oval cabochon pair in 9 x 7 mm — classic and versatile
The oval cabochon cut emphasizes color, texture, and natural character rather than faceted brilliance. Combined with the elegant 9 x 7 mm size, this pair offers strong visual presence while remaining highly wearable and versatile. It is particularly well suited for earrings, toi et moi rings, pendants, bespoke two-stone jewelry, and other custom-made designs.

Untreated rubies with natural character
As untreated rubies, these stones are especially appealing to buyers who value natural gem material without standard enhancement. Their matching format, attractive color, and practical size make them an excellent choice for jewelry that highlights the authentic beauty and timeless appeal of ruby.

A fine untreated ruby pair from Tanzania, combining elegant oval cabochon proportions, attractive pinkish red color, and strong potential for refined custom jewelry.
