I purchased this ring on LT a couple years ago. I do not believe the sapphire is heat treated, but I am not positive. The stone measures about 7x9mm. It has no surface blemishes. The color of this sapphire is hard to capture. It is a very silky pink/lilac with some slight flashes of orange. The color shifts in different lighting. The first pic was taken in incandescent lighting. The other one was taken in natural light on an overcast day. It is marked either 14k or 18k (can’t see it that well). It is a size 7.75, but can be sized by your jeweler. No returns.

Brand New. Stunning Natural Colombian Emerald and Diamond Ring set in a Platinum halo setting. The Emerald in the center around 1/3 ct is AAAA quality in color and clarity probably VVS1 or even IF in clarity. I took it to a jeweler who confirmed that and said he never saw such a Beautiful Emerald and he also said it's probably Colombian. The Emerald is 0.32 ct in an Emerald Cut. And there are 6 Baguette cut Diamonds and 8 round cut Diamonds all of good quality with a total weight of .30 ct. very well set. The ring weighs 5.32 grams which gives it a much more luxurious feel than a lower weight gold ring. I use paypal.

This ring is an authentic Edwardian original, dating to the early 1900s. Its age can be closely estimated through its materials and craftsmanship. Laboratory-grown rubies were first successfully produced in 1893 using the revolutionary Verneuil process and quickly became a fashionable alternative to natural rubies in fine jewelry at the turn of the twentieth century. This ring also features an 18k yellow gold mounting with silver-topped settings behind the diamonds rather than platinum, reflecting a brief but distinctive period before platinum became the preferred precious metal for diamond jewelry in the early 1900s. Together, these characteristics place the ring within a remarkably narrow window of history—the Edwardian era right at the turn of the century—capturing a fascinating moment in both jewelry craftsmanship and technological innovation. This lovely period ring makes a stunning statement ring, a meaningful July birthstone ring, or a truly distinctive engagement ring. At its heart glows an impressive antique cushion-cut laboratory-grown ruby, displaying a rich purplish-red hue that immediately draws the eye. The vibrant center stone is beautifully framed by a glittering halo of authentic antique diamonds, creating a harmonious balance of color and light. The surrounding collection of period-cut diamonds adds exceptional character, featuring an enchanting combination of single cuts, Old European cuts, Swiss cuts, and rose cuts. Their individually hand-cut facets produce a soft romantic sparkle beautifully enhanced by the dramatic darkened patina of the silver. White and bright when new, the silver has oxidized with time to achieve this much loved aged beauty. Despite its impressive presence on the hand, the ring has been thoughtfully designed with a low-profile setting that sits remarkably close to the finger, making it as comfortable for everyday wear as it is striking. Reserve this ring today with our 0% Interest Layaway Plan www.HeritageJewelry.com Video available by request or by visiting our Instagram page VanessaatHeritageJewelry Details Era: Edwardian, Early 1900s Center Stone: Antique Cushion-Cut Laboratory-Grown Ruby Ruby Measurements: 13.50 × 11.00 × 6.35 mm Ruby Color: Purplish Red Ruby Clarity: Transparent Ruby Origin: Laboratory Grown Accent Diamonds: Single Cut, Old European Cut, Swiss Cut & Rose Cut Total Diamond Weight: Approximately 0.62 Carat Diamond Color: Average Near Colorless to Faint Diamond Clarity: Average I1 Metal: 18k Yellow Gold with Silver. The band is gold, diamonds are set in silver-topped settings**This is not a gold plated ring** Ring Size: 8.75 (Resizable) Profile: Low-Setting Design for Exceptional Everyday Comfort Please note that historic resizing has cleanly removed the original hallmarks from the inner band. However, the metal composition has been professionally tested and is fully guaranteed as 18k yellow gold with a silver-topped face. The authentic Edwardian craftsmanship, regional metal layering technique, and historic hand-cut accent diamonds completely confirm its early-1900s provenance.

Debating on selling - I'm not quite ready to let this gem go! This is a very lightly worn 14kt white gold ring with a fantastic trichoic 1.8ct tanzanite surrounded by .28ctw mined graduated diamonds. The pictures don't do the trichroism justice - you can very clearly see green teal, blue, and purple in the tanzanite at different angles. Worn literally twice out of the house and perhaps a handful of times inside the home to admire the ring. I love this ring but rarely reach for it. It's currently between a size 3.5 and 4, but can be easily resized. Shipping to USA only Insured shipping not included in price $3000 USD PP F&F, or PP G&S if you cover the 3% fee. I'm a private seller so no refunds. I'm cookiecat on PS.
