First of all ...Asurazzy - Fabulous combination! Those Tahitians are gorgeous and those earrings...well they are amazing! They look wonderful!
Now .my two cents ..
It seems to me that ‘Harvest strand’ is a name that Josh used to describe the necklace design that used selection of all the different pearl shapes from his farm. Just like he uses Lagoon to describe the blue green silvery strands. It’s not an official term . It’s a design name that best describes aspects of the strand. Several companies that have made similar designs for years call them Cocktail strands. . I assume because it’s a mix of pearls in colour and shape. If you were to ask for a Harvest strand at the HK show , they wouldn’t know what you were talking about .
And, as someone who makes Cocktail strands and Harvest strands I can say it’s not that easy to get a nice balance of colour and shape and size. Especially if you don’thave buckets of pearls ! I tend to collect pearls specifically with a stand in mind . . Particularly the larger ones.
So for me , any strand with a selection of pearls of rounds , baroque, drops , circles and Keshi etc. could be called a harvest strand . I don’t know why they would have to come from one farm , it’s just a description. ( unless he trademarked it ..then it’s a different story) Strands that come from one farm would have their farm name in front of it to show its origin.
To wind up this long winded ramble, in my opinion you have , for example, a Kamoka Harvest Strand ...and regular Harvest strands ....and Cocktail strands that generally are different sizes but without Keshi. Again, just my outlook.
