This elegant ring features a stunning emerald-cut Madeira citrine gemstone measuring approximately 12 x 10 mm, set in lustrous 14kt rose gold. The centerpiece Madeira citrine displays the characteristic deep, reddish-orange hue reminiscent of fine Madeira wine, ranging from golden yellow to rich orange tones that distinguish it from standard citrine varieties. This warm-colored quartz gemstone is named after the Brazilian word for "wood colored" and is prized for its saturated, vibrant color.

The ring is adorned with 0.25 carats total weight of diamonds in VS2 clarity and I color grade, featuring a combination of 50 diamonds in round brilliant and baguette shapes that create an elegant halo and band accent. The design includes 4 baguette-cut diamonds and 46 round brilliant diamonds that complement the warm tones of the rose gold setting and enhance the fiery brilliance of the Madeira citrine center stone.

Madeira citrine is a type I clarity gemstone with a hardness of 7 on the Mohs scale, making it durable for everyday wear. This semi-precious quartz variety typically forms through heat treatment of amethyst with a brownish core, resulting in stable and permanent coloration. The gemstone sources primarily from Brazil's Rio Grande do Sul state, Uruguay, Zambia, and Madagascar. The ring comes in size 7 and is sizeable within one size, though this service is not provided by Costco.
