C. 1920 Vintage 1.75 ct. t.w. Diamond Dinner Ring with Synthetic Emerald Accents in Platinum. Size 7.5

PLATINUM: A rare precious metal cherished for its longevity and strength. Platinum is naturally white, durable, dense, and resilient to discoloration. Most platinum in jewelry is at least 95% pure since it does not require alloys or plating.

TEXTURED: A unique and varying finish with a tactile surface applied through various techniques, both by hand and with machinery.

Diamond: The hardest and most brilliant of all gemstones, a diamond can make the heart race with its pure and fiery spark. An ancient symbol of love, a diamond is the preferred gemstone for tokens of affection, such as rings, earrings, necklaces and bracelets. Diamond is the birthstone for April.

SINGLE-CUT: A gemstone cutting technique that dates back to the 1300s. Still used today, the single-cut usually features 18 facets that go in one direction without crossing each other.

Color Grade H-I: Near-colorless

CLARITY SI1-SI2: Slightly Included. Inclusions are noticeable under 10x magnification.

OLD EUROPEAN CUT: An old-fashioned gemstone cut dating back to the 1800s. With a round shape and 58 facets, it is considered the precursor to the modern brilliant-cut. However, it has a greater depth and smaller table than the brilliant-cut of today.

Color Grade G-H: Near-colorless

Clarity VS1-VS2: Very slightly included. Inclusions are observed with effort under 10x magnification, but can be characterized as minor.

SYNTHETIC EMERALD: A gemstone that is created in a laboratory to mimic the actual properties of a natural emerald. Commonly known as "created emerald," it features the same gallant green color and transparent radiance, but is significantly more affordable than an emerald found in nature.

TRIANGLE: A three-sided, pointed shape.
