Up for sale is a HPD New York setting Tiffany style ring mount in size US4.5. This ring has beautiful polish, has never been resized before and was rarely worn (retains a shinny polish without much signs of wear). It housed a 1.1 RBC diamond. (6.69 x 6.72 x 4.13mm) It is currently in size US4.5 and made with 950PT but can be resized easily. This setting was my dream setting for the longest time that I could remember. However I changed to a cathedral lower profile setting to fit my current lifestyle better. Even though I still do think the same :) I do have the original receipt and It was purchased in mid 2020. The original price I paid is $1800 and I am only asking for half the price :) Please kindly consider and email with any questions you may have. Lucyliu8023@yahoo.com

This is a platinum semi mount with baguette diamonds. I don’t know the weight of the baguettes but I would estimate 0.10 ctw. Very hefty setting. Size 9 and sizeable. Previously held a 6mm round brilliant diamond. One baguette is ever so slightly more tapered than the other - hard to notice unless you are staring at it but it is worth a mention. Open to offers. Price includes shipping to anywhere is US.

SOLD was 750...Clearing out the jewelry box because I do not wear my jewelry really anymore due to changing careers and becoming a nurse. Up for sale is one of my beloved rings. I am letting it go because it is not worn lately and I wear a different ring when I wear any at all. This was made to display and be enjoyed as I did. It is a Ritani semi mount ring setting from the masterwork series in their Bella vita halo settings which they do not make anymore. This comes from the elite rings from Ritani and what sets them apart in the halo rings from any average ring. Made in solid platinum to fit a 6mm round. I had my stone removed so it is ready for your stone and is desiged by Ritani to have minimal metal so your stone pops around the microdiamonds that are very high quality. Find a good jeweler to set your stone as bezel is harder to manage the metal and make sure they tighten the side baguettes. It is a 5,300 dollar semi mount that I managed to get for 2500 several years ago and I am letting it go because I will not wear it and I want to sell to someone who will enjoy this as well as the bargain but there is nothing wrong with this ring Model 1RZ3709btbr for .65-.75ct stone or 5.9-6.2mm the information said online for this ring. My stone was 5.99 or 6mm 80 micropave to make .24ct and 2 channel tapered custom cut baguettes on the sides to make .36ct in the color G-H and VS clarity. This information can be found on this ring. I bought it out of the display box at Bailey Banks Biddle when they had a store in Alabama..we fell in love with it in college and they had it there for 3-4 years and when they went out of business we bought it for the 2500 instead of retail. I wear a 5.75 to a size 6 depending on which finger and this fits both ring fingers. I had it sized to 5.5 and placed sizing beads at the bottom which can be removed easily to keep it from spinning so I am not sure what size to call it. This ring is sizeable but I am not sure how far up or down due to the side stones. I bought it as a 7 and sized it so I am sure a good jeweler can size it up or down a bit. 7grams on my scale- solid platinum-heavy Ebay had one of these for 1800 recently so this is an incredible bargain I am sure of it. There is no Ritani semi mount ring for this price on the internet that I could find. I am more than happy to email pics and answer questions the best I can--I consider this a fire sale-final sale to move it out --there are fees being taken out and considerable discounts here Shipping is included in the price- US only (too many past problems with international shipping) I have references here since 2007 as both a seller/buyer on the forums and on ebay since 2002 at 100%

Time to start cleaning out the jewelry box - have some vintage pieces that I don't wear, and should find a good home. I will most likely consign with Grace, but wanted to give it a short run here to see if there was any interest first. 1. Tiffany & Co 14K feather pin with small diamond. In pristine shape -- per my former mother-in-law, it was purchased by her mother from tiffany's many, many years ago (1960s?) and then given to her. Happy to drop by my local Tiffany's in Boston to have it authenticated, but it has been in the family since it was purchased. I will grab it out of the safe deposit box next week and can post an exact gram weight and measurements (I took these photos a little while, but did not post it for sale at that time). It is ~ 1.5 inches in length, 3/4 inch in width. 2. Art Deco semi-mount in platinum, size 5 (tight), 5.5 g, with 8 french cut sapphires and a handful of old single cut diamonds. It holds an 8mm round center stone. It was my engagement ring from a former relationship, and I had the stone remounted into a pendant last year. I finally decided to let the setting go as I feel I would not wear it again. Caysie of CVB ID unset the old center stone and preserved the prongs and said she felt it was in overall excellent condition. It was all original and was first purchased ~ 15 years ago in Georgia from a small antique jeweler (Lucy of Cameo Estate Jewelry, who has since passed on). Contact me for more photos - I have tons, and I am very happy to take more if you desire other angles, or tell you more about the pieces. Price will include insured shipping. As I am a private seller and these come from my personal collection, I cannot accept returns. ***update - LT email is not working, I can be reached at: akmongi at yahoo dot com --thanks

Gorgeous platinum Tacori-inspired engagement ring. Size 6-1/2 (sizeable), 950 platinum engagement ring/semi-mounting. Features an 8mm square radiant CZ center, with .56ctw of the most beautiful lemony sunshine yellow irradiated trillion diamonds. Truly a perfect canary yellow color. VS clarity. Setting also has 16 small round natural white VS diamonds set into the little scallops on each side of the band. 18k pen-plating around the yellow diamond settings gives a very subtle two-tone look. Truly a breathtaking ring. Center could easily be swapped for an 8mm asscher, princess cut, or cushion cut. Almost brand-new condition, only worn a few months before I remounted my center diamond in a different ring, and replaced the empty center in this ring with a CZ so it wasn't blank. Retail value is $3500 (even more if it were from Tacori or Verragio). Ring is not hallmarked due to previous sizing, but has been tested and is 100% guaranteed 950 platinum.
